By Bret Contreras Robert A. Panariello MS, PT, ATC, CSCS Professional Physical Therapy Professional Athletic Performance Center New York, New York In recent years the gluteal muscle group has received much notoriety in the physical rehabilitation, fitness, and sports performance industries...

By Bret Contreras Every once in a while a study comes along and alters my understanding of biomechanics and sports science. Effects of weighted sled towing with heavy versus light load on sprint acceleration ability by Kawamori et al. was published ahead of print earlier this year in March...

By Bret Contreras I came across this study last week and chalked it up as “interesting.” All research is useful, but often you have to simply file it away in it’s place until more research is conducted. The study was published ahead of print in The Journal of Strength & Conditioning Research...

You know when you’ve been in a deficit for a while, and things start to feel a bit sucky? Hunger is high, you have the energy levels of a sloth on Xanax, you’re irritable, and you start to question whether this dieting stuff is even worth it. Well, friend, you’re in luck! I’m about to tell you...

A couple recent studies have shown that HMB – a legal supplement – works better than moderate-dose steroids. Is it the next wonder-supplement or just hype? I’ve been debating for a few days about whether I should write about this HMB controversy or not. I’m quick to call out ideas that are...

The most reliable way to make progress is to do more. It’s certainly not the ONLY way to make progress. Exercise selection plays a role, intensity plays a role, frequency plays a role, proper periodization plays a role. But the primary contributor – hands down – is training volume. It’s been...

Can you build muscle on a ketogenic diet? Yes. Is it the fastest way? Not for most people. In fact, there’s no compelling evidence to show that keto offers any muscle-building benefits that you don’t get with a higher-carb diet providing adequate amounts of protein and fat. If you’ve got some...

Food Sequencing for Metabolic Health Food, Fat Loss, and Credibility There are many different ways to think about food and fat loss. Unfortunately, the view that calories are all that matter dominates most discussions. Anyone who says calories don’t matter for fat loss is either ignorant of...

The next time you see someone using one of these training implements, do them a favor and shove them off. Here's why. TAGS TRAINING Despite what we've learned about the ridiculousness of most instability training for athletes, there isn't a training day that goes by when I don't see some yutz...

You may think you're training hard, but are you really selecting the right weight for the rep range you're working in? This study highlights the important differences in weight selection in people who train by themselves versus those who train under the supervision of a coach or personal...

THE LEG DAY DILEMMA It's leg day and you have a decision to make. You're really not feeling it today. You take a look at your workout plan and groan. What do you do? As a dedicated lifter, you're not going to miss a scheduled workout. So should you stick to the program you've been following and...

LESS REST FOR SIZE, MORE REST FOR STRENGTH? The advice regarding inter-set rest periods has long been that rest and intensity are inversely related. In other words, if you did a lighter weight, higher-rep set, you rested for anywhere from 45 seconds to a minute. If you did a lower-rep heavy set...

Let's say you injured yourself. Maybe your thigh collided with the Frankensteinian head of some gi-normous Australian rugby player during a scrum from hell, or you just wanged your shoulder on the door jamb while racing back from the kitchen with a bag of Doritos to catch the next big reveal on...

Eat More But Lose Fat and Gain Muscle Bodybuilding’s holy grail, its equivalent to the quest for nuclear fusion, has always been the diet that allows you to put on muscle while cutting fat. Oh, some of the keto people will tell you they have that covered with their diet, but aside from being...

BAD SCIENCE A few years ago, researchers from the University of Texas Health Science Center reported that diet sodas made people fat. In fact, they got pretty damn specific about it. They said that every can of soda you drink increases your chance of being overweight by 41%. I'm not even sure...

The ketogenic diet is one of the hottest diet trends at the moment. Not fat-adapted yet? Not putting sticks of butter in your coffee? Welp, you can't sit with us! (A sarcastic reference to Mean Girls, in case you missed it.) I don't know what's more disturbing – putting sticks of butter in...

YO-YO DIETING Dieting is a chancy undertaking. The sad truth is that most people who attempt to lose weight end up gaining it back. In fact, at last count, there are only five people on the entire planet who have permanently lost weight, but even that pathetically small number is suspect...

Vickie stays lean all year long. She always looks like she's a few weeks out from a figure competition. Everyone hates the bitch. No, they don't hate her, but they all want to know her secret. When asked, she just says she eats "clean." But it's not a willpower thing. Vicky just doesn't like...

While Joe Weider often gets the lion's share of credit (or blame) for popularizing bodybuilding supplements, Vince Gironda, aka "The Iron Guru," was the true father of supplementation (along with a whole lot of nifty training concepts). Gironda also popularized being kind of an SOB. I...

Vitamin D deficiency is common. Fewer people are getting outdoors, and those who are vitamin D deficient will get even less during winter months. As you know by now, this has numerous health implications. But new research by Jung et al. found that vitamin D status can influence performance as...
