Train smarter with science.

Easily interpret and apply the latest strength, hypertrophy, and nutrition science with Monthly Applications in Strength Sport (MASS).

1,000+ new exercise science and nutrition studies are published every month. 

You know that keeping up with the latest science is crucial to being the best athlete or coach you can be.

Even if you just lift for fun, you want to be sure you're getting the most out of your time in the gym.


Trying to learn more about science-backed training and nutrition strategies can be extremely frustrating, especially on the internet.

Anybody with a little chutzpah and time to kill can start their own website or YouTube channel and start presenting themselves as a "fitness authority." The information they're presenting is typically of dubious quality at best.

Trying to gather information in the gym isn't much better. You could ask the biggest dude in the gym, but there's no guarantee that he got jacked because of his training, and not in spite of it. You could ask the overeager trainer, but they're just going to blindly recite whatever they heard at the last seminar they attended. Finally, there's the grizzled veteran who'll tell you what they did in the "good old days," but who hasn't kept up with recent advances in training and nutrition science.

But since you know it's important to keep up with the latest science, you try to do it all yourself.


Going through the studies each month is extremely time-consuming. Spending time figuring out how to apply them all is difficult. Having access to all the different journals is expensive. Interpreting research and figuring out which studies are trustworthy and applicable to you is frustrating.

You want the benefits of knowing the latest science and want to stay on the cutting-edge of training and nutrition, but you don’t have the time, energy, and money to sift through the journals, pick out which studies are applicable, analyze their design for trustworthiness, critically read them, and figure out how they apply to you training or your client’s training. Doing that for just one study is quite a task. Now imagine doing it for 1,000+ studies across 50+ different journals. For most people, that's just not feasible.

So what happens if you can't keep up with all that incoming research?

One of two things usually happens when someone doesn't keep up with the literature.

If you’re depending on headlines to keep you up-to-date, it’s super easy to get swept away in a fad because you don’t understand how new findings fit into the overall body of scientific literature. You’ll constantly be chasing the next new thing, but never actually getting anywhere.

On the other hand, you could end up sticking with a training or nutrition concept that’s been abandoned and updated with new, more relevant findings. You end up stuck in old ways of doing things and not taking advantage of evolved and improved discoveries.

So you know you need to keep up with the science, but you also know that – up to this point – doing so required time, energy, and money that you just don't have.

The three of us (Greg, Eric, and Mike) have committed our careers to helping alleviate this problem. Now, we're coming together to smash that problem for you once and for all.


Be an expert in strength and physique sport without wasting any time, energy, or money.

Introducing, Monthly Applications in Strength Sport (MASS). 

If you're serious about getting the most out of your time in the gym, and you're fed up with the confusion of trying to sift through the conflicting information that's out there, MASS is for you.

MASS is a shortcut,  a “secret weapon” to put you head and shoulders above the rest. An athlete or coach who knows and truly understands the latest great research has a huge advantage over his competitors.

Every month, we sift through 50+ journals and 1000+ studies to handpick the cutting-edge research that's most relevant to you, and will help you build muscle, gain strength, and get leaner.  All three of us are athletes and coaches as well, so we know how to separate the truly valuable and applicable studies from the novelties that are never going to make it out of the lab and into the gym.

If you're tired of wasting your time reading a dozen conflicting opinions about every facet of training and nutrition, you don't have 40+ free hours every month to keep up with the scientific research for yourself, and you're serious about learning how to optimize your training, nutrition, and recovery practices to get the best results, MASS is the best investment you can make.

MASS is one of the best investments an intelligent lifter can make. So many people want to know what the research REALLY says but don’t know who to trust to tell them the truth. MASS takes the guesswork out of it by distilling down the hardcore, cutting edge science into a palatable form that is easy for anyone to understand and implement practically into their own training.

As a coach, the pressure to stay on top of the latest research findings can be overwhelming, as it is something my clients and readers count on me for. So when my colleagues Greg Nuckols and Eric Helms told me they were putting together a research review with Mike Zourdos I was immensely happy. These are two of the smartest and most analytical gentlemen in the industry and I trust their opinions entirely. Better still, they are humble, which is something rare in our fitness industry which is full of big egos. They are not tied into any dogma, and I know I can trust them to update their opinions and advice when research comes out that justifies it.

More and more trainees and coaches are seeing the value in taking an evidence-based approach to their training, nutrition and coaching. While this is almost certainly a great thing for the industry, it does carry it’s challenges for those who want to base their practice on actual research… How does the average strength trainee accurately pick apart primary research studies? How does a full-time coach find the time to dig through the 1000’s of new studies that continue to emerge? How do we know if our interpretation of a research paper is accurate? Well, that’s where MASS is worth its weight in goldGreg, Eric and Mike do all the initial leg work for you! I honestly can’t think of three other guys on the planet that I’d want to break down a strength training study for me. Their knowledge and practical expertise is only matched by their integrity and objectivity. So to me, this is a no-brainer for any strength coach, training enthusiast, powerlifter or bodybuilder who is serious about what they do; you should 100% be subscribing to MASS and absorbing all this info every month.

Monthly Applications in Strength Sport (MASS) looks to be just what the strength coach needs in this burgeoning time of increasing research specifically for barbell & strength sports. Most coaches don’t have the time, access to journals, or the scientific background to break down complex studies and see the practical applications. MASS tackles effect sizes, population considerations, p-values and the like with ease, letting you know how applicable varied studies are. Each issue feels hefty, packed with veritable powerlifting gold. From hypertrophy and volume to lifting technique and nutritional concerns, nothing important to the strength athlete is left out. Thanks to the hard work of Eric Helms, Mike Zourdos, and Greg Nuckols, we’re privy to a beautifully presented and well digested blend of study reviews in both written and video content. Who else does video?! And I mean lengthy videos with slide presentations, clear and sequential ordering, and a breakdown of complex topics in lay terms. The studies themselves are presented with key points, findings, and most importantly, expert interpretations. From three industry-leading experts in strength sport come this companion to the coach or inquisitive athlete—a resource to turn to again and again as you build your skills and strength.

As someone who loves to consume the most up-to-date training and nutrition science, but doesn’t always have the time to read research, MASS provides an incredibly valuable shortcut to high-quality literature and its practical application. MASS ensures that every month my knowledge base is completely up to date so that whether I am coaching a client, conducting an interview or creating online content, I’m confident that I’m up to speed with what is at the cutting edge of our community.

I hate reading research. Right behind people who don’t turn right on red. When people smarter than myself are willing to hang out on PubMed, dissect things, and put them into tinier morsels of information that will not only help me stay on task with current, evidence based trends in strength & conditioning, but also save me time….I am all for it.

MASS is the perfect resource for athletes, coaches, and general fitness enthusiasts alike. Sifting through the infinite amount of fitness related information at our disposal is time consuming and frankly confusing in order to determine which sources to trust and rely on. MASS makes science-based fitness research accessible, easy to understand, and applicable, which is invaluable in the day of unlimited access to information that may not be always accurate or of value. MASS serves as a tool for those interested in a solid foundation to apply to their own lives and the lives of others.

When I was first introduced to MASS, I loved the concept and knew it would be highly applicable to myself as a coach and an athlete. After reading the first issue, I was blown away by the quality of the review, the straight forward writing style and how contextual it was to the target audience. If you are a physique or strength athlete, coach or just someone who loves the science behind training, you will not find a better research review. I can’t speak highly enough about this review!

You may be wondering...

How is this different from other research reviews? 

MASS is the research review for strength and physique athletes and coaches.  Other research reviews in our area do a great job keeping you up to date with research into general health and fitness, nutrition research, and research relevant to S&C coaches that work with athletes from other sports, but no research reviews focus exclusively and specifically on people who want to gain muscle, get stronger, and improve their body composition.

If you're a powerlifter, weightlifter, strongman, CrossFitter, bodybuilder, physique competitor, or a coach for a strength or physique sport, you'll open your issue of MASS every month to see 7 articles and 2 videos that are very relevant to you, helping you get an edge on the competition. If you fall into one of those groups, MASS is perfect for you.
