Wait a minute…. you’re telling me to restrict blood flow while resistance training?  Doesn’t that lead to blood clots, embolus, etc.?  You’re out of your mind man.”  We hear this conversation far too often when discussing a novel technique used to induce muscle growth.  When considering resistance-training variables, everyone traditionally mentions drop sets, supersets, different periodization models, etc.   Now that you’ve incorporated and tried those techniques, it is time to add a new tool to your repertoire.  Lets examine what BFR is and how you can incorporate it into your training program.


Blood flow restriction (BFR) {sometimes called occlusion training}, as the name implies, involves decreasing blood flow to a working muscle, by application of a wrapping device, such as a Kaatsu device, blood pressure cuff, or knee wraps.  This technique is typically used in conjunction with lighter weight (30-50% 1RM) and performed on the legs and arms, although some research suggests that there may be benefits for other body parts as well (Yasuda et al).  Interestingly enough, some research shows that even walking while BFR can increase muscle size!! (Abe et al)  Thus, the real question becomes:  How in the world is this happening?!?



There are several mechanisms through which BFR may work but we will touch on the 3 primary mechanisms:

1)     Increased Muscle Activation/Motor Unit Recruitment

Typically lifting 30-50% of your 1RM trained to non-failure would only target the Type I (slow twitch fibers).  However, with BFR + exercise we see that even 30% of your 1RM can target the larger, Type II fibers that are important for muscle growth and size.  Interestingly enough, Yasuda et al (2010) found greater muscle activation in the chest muscles when wrapping the cuffs at the top of the arm and performing a bench press movement.  This indicates a possible benefit for muscles other than the ones that are purely “restricted.”

2)     Increased Metabolic Stress

Don’t fear.  Acute metabolic stress, such as that seen when training can actually be a good thing.  One of our colleagues Dr. David Gundermann found that the plasma lactate response seen during BFR at 30% 1RM was significantly higher than high volume workouts using 70% 1RM!  Why does this matter?  In fact, research indicates that increased metabolic stress was linearly associated with changes in muscle cross sectional area.  As if that wasn’t enough, Dr. Gundermann did an experiment where he took muscle cells and exposed them to lactate.  Just exposing them to lactate alone drastically increased downstram targets of mTOR which we all know is the master regulator of protein synthesis.

3)     Increased Cell Swelling

Arnold used to say he “trained for the PUMP!”  Maybe he was on to something because there appears to be evidence that intracellular metabolites cause cell swelling which may activate anabolic pathways.

Stop lifting heavy weights.  Everything you have been doing has been a lie.  Just kidding again.  It’s important to remember that this is a TOOL to use in addition to your regular resistance-training regime.  You can use it as a finisher, but you can also use it if you’re flat out tired, injured, or just want to train on Saturday yet you still feel like you got hit by a truck from a Friday night out.  Some important considerations to consider:

1)     Scheme Typically Used Is: 30-15-15-15 reps with 30 seconds rest:

Keep rest periods short.  Its all about pumping them out and keeping that metabolic stress and cell swelling up.

2)     Its Not about Damage:

One of the kings of BFR, Dr. Jeremy Loenneke, did an interesting study that showed that the concentric portion of the contraction seemed to be more important than the eccentric.  The goal with BFR isn’t to create muscle damage.  Pump out the reps with proper form…proper form aka don’t be the guy at the gym doing the hip thrust – bicep curl combo workout.

3)     Wrap at a moderate, snug pressure:

If you can imagine 10/10 being as tight as humanly possible, our lab has found that at about a 6-7 out of 10 is ideal.

4)     Device:

You can use knee wraps or even plastic tourniquets:

5)     Keep your Wraps On:

It will be painful and it will hurt but keep your wraps on the entire time (30-15-15-15).  Now if you start turning blue/purple, that might be a time to release them and rewrap.

Our lab and as well as others (Leubbers et al) found that doing your supplemental work with BFR can result in significant gains in muscle size.  So as a take away, you can use BFR when you are injured, as a finisher for your workout or as an entire workout itself on a day when you feel pretty crappy, yet still want to get some work in.

Variable resistance training, or VRT, has been a fixture in powerlifting for decades. In this context, VRT specifically refers to resistance training with elastic bands or chains attached to a barbell, mostly in the squat, bench press, and deadlift exercises. These are not thera-bands or machines with lumpy cams; we’re talking about real-deal exercises with bands or chains creating load in addition to the traditional plates. It is referred to as VRT because the resistance changes throughout the movement, increasing as the lifter approaches the lockout. VRT can also be called accommodating resistance, as the resistance is accommodating the “strength curve,” meaning the resistance is greater in the range of motion which the lifter is usually stronger.

You might be thinking, “but if I’m already stronger in that range of motion, why the hell am I training it? I don’t get stuck at the top!” There are two components to power generation, force and speed. We all know force is necessary for moving serious weight, but speed, and momentum, is often overlooked. If you get stuck about 3 inches off the chest in the bench press, then that 3 inches can be used to generate momentum to help press through the sticking point. VRT emphasizes maximal power generation through the entire range of motion – you have to work harder at the bottom to get through the top. This can be achieved by working both sides of the power equation, force and speed.

Speed training, or dynamic effort training a la Westside Barbell, uses submaximal loads with the goal of fast bar speed, and it is an underutilized tool for many intermediate level lifters. Everyone knows lifting heavy can make you stronger, but few realize lifting fast can make you stronger too. The first research study I ever conducted compared a traditional 6-week strength and conditioning program to the exact same program with bands added to the squat and bench press exercises once per week on the dynamic effort day. The group with added bands had greater increases in strength than the traditional training group.  More recently, Soria-Gila et al. found that in 10 out of 11 studies researching VRT, the VRT group experienced greater improvements than traditional training.

So how do we use bands or chains? First, load is important. Somewhere around 30% of 1RM from band tension currently seems ideal for speed training with 40-60% 1RM as traditional free weights. When I say 30%, I mean 30% at the top, or at the bands longest length during the lift. At the bottom of the lift, the band or chain ideally is providing very little to no tension. However, you do not want the band to go slack more than 1/2 inch from the bottom of the range of motion. If you do not know the tension of your bands at particular length. You can pull a MacGyver and figure it out by hanging a weight from the band and measuring its length with a tape measure. To fine tune the tension, you can wrap the band around the bar a few times. Second, great gyms will have squat racks and benches with band pegs, but other times you can secure them to a dumbbell or the bottom of the rack. Make sure it’s a heavy dumbbell; if it comes off of the floor, that’s called crazy bells, and that’s fun, but it’s not what we’re doing – get a heavier dumbbell. On the bench press, you can also wrap the band underneath the bench. It’s a bit more precarious and awkward, but it gets the job done. Third, always remember that this is SPEED TRAINING. Move the freaking bar like you mean it. For 2-5 reps, 3-8 sets.

For strength training (i.e. max effort method) with accommodating resistance, add 10-25% 1RM as band/chain tension to 80-95% free weight. 3-5 sets. 1-5 reps. This is the same setup, just a different application. For strength adaptations, both bands and chains are great, but I favor chains or chains with a light band. Conversely, I will always use bands over chains for speed training due to their multiplicative nature. Let me explain. Bands will get harder faster, and chains will get harder at a constant rate. For example, for every inch a band is stretched, it will increase in resistance by 1lb for the first inch, 1.5lbs for the second inch, 2.5lbs for the third inch, 4lbs for the fourth inch, etc. but chains will always add 2lbs per inch it is raised from the floor. Don’t quote me on the exact numbers, but you get the point. I also like bands because you can use them against gravity as well as with gravity.

What I’m talking about is called reverse bands. Not only does this get your ego yoked, but it’s a great tool for getting mentally and physically comfortable under near-max loads as well as work on power development out of the hole in a manner more akin to heavy lifting. It similarly accommodates a strength curve, but instead of adding variable resistance in the concentric, it variably removes load as you descend. For reverse bands, it should be obvious from the name, but you attach the bands to the top of the rack instead of the bottom. Then you toss another plate on the bar and legally change your name to Billy Badass. Use bands this way if you fail in the hole, off the chest, or off the ground. This means you suck at changing direction in the squat/bench or at initiating the pull in the deadlift and can help fix it with the reverse band exercise. That being said, if you have bad technique, then reverse bands will not help you much – fix your technique! The reverse band exercise is also great for improving bar speed with heavy loads, and leading up to a 1RM test or meet for building comfort with heavy, supramaximal weight.

Now we know VRT can help you get stronger and more powerful, but what about bigger? I’ll change the exercise here to meet a bodybuilding application and discuss the leg press. We all had a friend or classmate growing up that thought it was awesome to half-rep a few hundred pounds on the leg press. If you didn’t have one, you might need to check your range of motion next time you leg press. Anyway, the point is that the top half of a leg press is easy-peasy. As a result, we don’t really need to keep pressing very hard once we get out of the bottom to complete the lift, and in fact it is discouraged to press so hard that the sled flies off of our feet. What can we do? I think you know. We can accommodate the strength curve. Using bands, we can increase the load selectively at the easy range of motion to make it harder at the top and get a better contraction in the quads.

In short, bands make you faster, stronger, and bigger, and you should really start using them in your training.

If a little exercise is good for you, more must be better – right? Possibly, but sometimes it’s not. In the pursuit of better health and fitness, it might be difficult to take a break from exercise. If exercise is leaving you more exhausted than energized, you could be suffering from overtraining syndrome.

The goal of exercise is to challenge your body so that it will adapt. Whether that adaptation is the ability to run a marathon or lift 500 pounds, exercise causes a significant amount of stress to create this adaptation. The time it takes for your body to adapt to exercise is dependent on a multitude of factors. These factors include: volume/intensity of workouts, nutrition, sleep and any other stress in life. This stress only becomes a problem when you reach a certain threshold. When this happens your body loses the ability to adapt. The threshold occurs when the body can’t recover from exercise, which is when prolonged maladaptation occurs. This is calledovertraining syndrome. By using the expression “syndrome,” I want to emphasize the multifactorial etiology and acknowledge that exercise  is not necessarily the sole causative factor of the syndrome.

Overtraining syndrome(OTS) is of growing concern in an era when athletes push themselves to get an edge on the competition. Likewise, the ambitious college student can even have trouble with training too much. It has become clear that proper exercise prescription is important to avoid pushing your body past its limit. The easiest way to avoid this is by periodized training. Simply put, periodization allows variation and includes phases of high training and planned periods for recovery. This strategy of training applies to elite athletes as well as to individuals exercising for general health.  While going over the details of how to periodize your training is beyond the scope of this article, you can find more information here and here.

Nutrition also plays an important role in recovery. If your nutrition is insufficient it will become even more difficult for your body to recover. There is not a specific nutrition program that will prevent OTS, but eating adequate amounts of protein, carbohydrates and fat will ensure that your body has the substrates to recover. It is thought that the fatigue and under-performance associated with OTS are partly attributed to a decrease in muscle glycogen levels. Glycogen depletion results in higher circulating levels of catecholamines, cortisol, and glucagon in response to exercise while insulin levels are very low. Such hormonal responses will result in changes in substrate mobilization and utilization. Other than carbohydrate depletion, dehydration and negative energy balance can increase the stress response which further increases the risk of developing  symptoms. Thus, to reduce the symptoms and reduce the risk of developing OTS during periods of intensive training, individuals should increase their fluid, carbohydrate, and energy intake to meet the increased demands. Additional carbohydrates should not be at the expense of reduced protein intake because there is some evidence that insufficient protein can also result in increased risk of OTS.

This syndrome reflects the body’s attempt to cope with physiological and psychological stressors. If you find that your strength, size or stamina have plateaued for an extended period itmight be that you’re not giving your body enough time to recover. Currently, several markers (hormones, performance tests, psychological tests, and biochemical and immune markers) are used, but none of them meet all the criteria to make their use generally accepted to serve as a test for OTS. Therefore you must pay attention to signs from your body to know when to reduce workouts. The only way to recover from it is to rest and then slowly begin workouts again. The  emphasis needs to be on prevention of  OTS and on early diagnosis, which at least in principle might shorten the recovery time. If you find yourself in a situation where your body isn’t responding well to exercise, it might be a good time to taper off or take a break.

Overtraining syndrome — an accumulation of training and/or stress resulting in long-term decrement in performance capacity with or without related physiological and psychological signs and symptoms of maladaptation in which restoration of performance capacity may take several weeks or months.

Individuals who exercise excessively are risking more than poor performance, they’re risking their health. The general symptoms for overtraining from the American College of Sports Medicine include:

  • Decreased performance.
  • Agitation, moodiness, irritability or lack of concentration.
  • Excessive fatigue and malaise. 
  • Increased perceived effort during normal workouts.
  • Chronic or nagging muscle aches or joint pain.
  • More frequent illnesses and upper-respiratory infections.
  • Insomnia or restless sleep.
  • Loss of appetite.
  • Chronically elevated heart rate at rest and during exercise.

You’ve seen this motto since you were in high school. You may have even perfected the training and eating part, but what about sleep? How can it affect your body? How many hours do you need?

In the past few years, a drop in the duration of sleep time has become evident in the population, especially in colleges and among those ages 18 – 39. Whether this is from an increase in video games or a boost in online television streaming, it doesn’t really matter. What does matter is that this sleep deprivation leads to impaired cognitive, metabolic, and hormonal functions.

Stop destroying your body by not sleeping enough.

From a metabolic view, almost all human studies show that sleep deprivation favors an increase in body mass. Not the good kind of mass either – rather, an increase in fat mass. These studies show that this is caused by an increase in appetite. You would think that it would be the opposite, since you’re awake more you burn more calories. However, this isn’t the case.  Short sleepers have more time to overeat and also show a preference for fatty foods.

The two hormones that control appetite are leptin and ghrelin. Ghrelin works to stimulate appetite and increases with less sleep.  Leptin works in the opposite way, inhibiting appetite and it is decreased with sleep debt. This causes a ravaging system that actually makes you want to eat more. That’s not the whole story though.

Other hormonal changes induced by a lack of sleep occur in the Hypothalamic-Pituitary-Adrenal axis. This leads to two distinct outcomes: increased secretion of cortisol and significant changes to anabolic hormones. As you probably remember, cortisol causes muscle breakdown, fat deposition and even decreased immune function. To optimize muscle growth and performance you want to reduce your overall levels of cortisol. Now, it’s as simple as sleeping.


Insulin resistance has been reported in young people with sleep deprivation. Furthermore, IGF-1 is rapidly reduced under conditions of sleep deprivation. This creates a catabolic atmosphere. One study showed that subjects on a 14-day diet had similar reductions in body mass as those who slept 5.5 hours per night. However, the subjects who slept 5.5 hours had a much higher loss of muscle mass, as much as 60%. This tells us that muscle mass is regulated by a distinct pattern of hormones and requires sleep to maintain itself.

Sleep plays an important role in muscle recovery, whether the damaged is caused by exercise or injury. Sleep debt damages the muscle by an increase in protein degradation (muscle mass) which helps muscles to shrink, not grow.


The Muscle Clock

Muscle, much like every other tissue in the body, has circadian rhythms. Circadian rhythms are oscillations in biological processes over a 24 hour period. These oscillations are important because they allow you to anticipate changes in the environment.

These rhythms modulate the expression of a huge number of genes in skeletal muscle, many of which aid in muscle recovery and protein synthesis. The rhythms may be synced by cues such as light, time of feeding, and time of activity. However, if the rhythms are disrupted or asynchronous, it can cause major problems. This leads us back to not sleeping enough. When you shift your biological clock by going to bed at 2am instead of the normal 11pm, your body tries to adjust. Now, if you were to continue that pattern it would adjust normally within a week or two, but if you have a sporadic sleep schedule the body can’t resynchronize. It’s like having jet lag all the time. Basically, you’ll feel like shit.

The expression of genes involved in metabolism has been shown to oscillate in muscle. In fact, one of the largest groups of oscillatory genes consists of those in substrate metabolism. Since muscle is a key metabolic tissue, it is important that these be properly synchronized for normal metabolic function.

Testosterone levels follow a circadian rhythm, which bottoms out in late evening and starts to ascend during sleep with a peak in the morning around 8am. Though there appears to be a limit at which sleep duration does not accumulate more testosterone. This limit appears to be 9.9 hours. Importantly, sleep duration and disturbances affect testosterone levels as well as muscle mass and performance. This indicates that sleep plays an active role in the regulation of sex hormone function.

Changes to the circadian rhythm are set once you’re an adult, but during the teen years it undergoes significant changes. This occurs when most teens experience a sleep phase delay. This shift causes teens to feel alert later at night, making it difficult for them to fall asleep at a decent hour. Compounding this problem, most teens start school early which can make it difficult to for them to get the sleep they need, an average of 9.25 hours.

So how many hours do you need? Contrary to what some people believe, you need 7-8 hours of sleep. People may say they only need 5-6, but this just means they aren’t functioning at their full potential. Plus, they will eventually have to make-up that sleep debt or suffer an increased risk of chronic diseases.

There are many sleep-deprived people due to demanding lifestyles or medical conditions (shift-workers, insomnia, and other sleep disorders) or even just being a teenager. Don’t let sleep be the limiting factor for your performance and cognitive goals.

Women need to lift.  It’s as simple as that.  Not only to look better and be stronger, but also because it’s good for us.  It’s good for your bones, increasing bone mineral density and protecting against osteopenia and osteoporosis.  It increases lean mass, which in turn increases your resting metabolic rate, or the number of calories you burn on a given day just laying around doing nothing.  It’s good for your self-esteem, and can improve both body image and overall perceptions of well-being.

So what is a girl to do who is looking to start a weight training regimen but has no idea where to start?  Well, for one, get off the treadmill and into the weight room!  Check out what the guys in the gym are doing, at least the ones who look like they have a clue.  Chances are, if it works for the guys, it will work for us too.  But don’t worry, you aren’t going to get huge if you lift like a man – guaranteed.  That’s just not possible.  We don’t have the testosterone levels and never will.  You will get stronger though, and particularly if you squat regularly, you’ll end up with a firm, rounded posterior that will be the envy of all those cardio queens.  If you want to be stronger than ever, have more defined muscles, and an athletic physique, then look no further.  This 4-week intro to strength training program will put you on the right track, because let’s face it ladies, strong is the new sexy!

Below is an example of how you might train each week.  You don’t have to do MWF, but you should lift on non-consecutive days since you’ll be hitting all of the major muscle groups each time you lift.  48-72 hours between lifting sessions is sufficient, but don’t be alarmed if you are still experiencing some muscle soreness from the previous workout, especially if you are a beginner.  When in doubt, consult a certified personal trainer or strength and conditioning specialist to advise you on form and technique. Or just ask one of the gym rats, they’ve been wanting to talk to you anyway.

Start with a light warm up set before moving into your work sets.  That is, use the empty bar or a light weight you can easily lift for 10-15 repetitions just to get the movement down and prepare your muscles to do work.  Mondays will involve sets of 10-12 repetitions of each exercise (for one arm row, that’s 10-12 per arm) with a weight that just allows you to finish the prescribed number of reps, but not more than that.  This will take some trial and error initially, but you’ll figure it out pretty quickly and build from there.  Rest 60 s between exercises/sets.  Core work will always be a higher number of repetitions (15-20 per set) for any given workout, as you want to develop local muscular endurance in this region that will improve core stability and help with the rest of your lifts.

Wednesdays are sets of 8 repetitions with 1-2 minutes rest between exercises/sets, using a moderately heavy weight that just allows you to complete 8 reps but no more than that.  Fridays will be your heaviest weight lifting days, don’t be afraid!  You’ll only be doing 6 repetitions, but it should be challenging, i.e. don’t use the same weight you used Monday.  You get to rest for 2-3 minutes, which is plenty of time to recover even though the weight is heavy.  Be certain to focus on proper lifting technique and breathing.

Use the 2 x 2 rule for increasing weight on a particular exercise (don’t know the 2 x 2 rule?  Check it out on MPSSI’s website: ) so that you continue to build strength each week.  As long as you’re making progress (increasing the amount of weight lifted on a given exercise) you may choose to repeat this 4-week cycle using 3-4 sets once you’ve finished the initial one.  Want to mix things up?  Try switching between dumbbell, barbell, and cable variations of exercises.  The key is to stick with it!

Concurrent training is inclusion of both resistance and endurance training within the same training program. For example, if you lift weights on Monday and run a few miles on Tuesday, then repeat this pattern throughout the week or in the same day, you are training concurrently. This can be advantageous for reducing body fat compared to resistance or endurance training alone, as strength training typically does not yield decrements in body fat, and endurance training reduces lean body mass, strength, and power in trained individuals. However, concurrent training does not produce as great of an increase in muscle mass or strength as resistance training alone, nor does it produce as great of a loss of body fat as endurance training alone.

Progress may be halted by the large volume of work necessary to perform both modalities simultaneously by pushing the athlete into an overreached or overtrained status. However, those accustomed to higher workloads should be able to handle high volume. Therefore, it is more likely that stalled progress is due to competing adaptations. Wherein, resistance training adaptations (i.e. increased muscle mass, strength, power, and maintained oxygen consumption) compete with endurance training adaptations (i.e. reduced muscle mass, strength, power, and increased oxygen consumption). Much of this difference can be attributed to muscle size. It is advantageous for strength and power athletes to have large muscles, as larger muscles have higher force output, yet they also increase the diffusion distance for oxygen, making it more difficult for the mitochondria to receive oxygen to produce ATP (energy). Thus, it is beneficial for endurance athletes to have smaller muscles to oxygenate, and the longer duration you perform steady state cardio, the more muscle and strength you lose! Reduced muscle also reduces basal metabolic rate, making long term fat loss more difficult. At this point, you might be wondering, “what the hell do I do then? Concurrent training is bogus!”

For primarily anaerobic athletes such as football players, or those who just want to be huge and ripped, it is not worthwhile to perform much steady state cardio for the reasons listed above. Instead, cardiovascular activity for these sports should be primarily of very high intensity (90-100+ %) and short duration (10-30 sec) with fairly long rest periods (2-4 min). This type of cardio (also known as HIIT, or high intensity interval training) will impede resistance training adaptations less than steady state cardio. Of course, these athletes should weight train often, 3-7 days/week depending on training status.

For anaerobic and aerobic athletes such as basketball or soccer players who are active for a long duration, but also intermittently sprint, limited steady state cardio can be helpful. Although keep in mind that it will blunt increases in power from resistance training – don’t overdo it; once per week is sufficient for most individuals. The cardio train doesn’t stop there. Perform HIIT 2-5 days/week in addition to the steady state cardio depending on your sport and training status… then run through people like a train (this requires 3-5 days/week of resistance training).

For purely aerobic athletes such as marathoners, concurrent training is highly preferred! Rejoice! However, long duration steady state cardio should still only be performed once or twice per week with a focus on technique. HIIT, and other forms of higher intensity training such as fartlek and pace training, alone is very capable of increasing endurance, not only via increased oxygen consumption, but increased lactate threshold and/or lactate clearance. The maximal lactate steady state (MLSS) is arguably more important than maximal oxygen consumption for endurance athletes. MLSS can also be positively influenced by resistance training. Moreover, resistance training increases muscular tone. Increased muscular tone, when running, reduces energy lost to “rebounding” off the pavement, for example. In lax muscles, energy is required to absorb the force of contact with each step, yet tense muscles will absorb the force without expending as much energy. Weight training will also not blunt endurance adaptations if performed at a high intensity with low volume (i.e. without inducing muscle growth).

In summary, concurrent training reduces increases in strength, power, and muscle associated with resistance training. On the flip side, it enhances strength, power, muscle, and basal metabolic rate for endurance training alone. HIIT is recommended to reap the benefits of concurrent training without the drawbacks associated with steady state cardio.
