Keeping up with the 1,000+ new studies published per month is crucial, but quite challenging.

You want the benefits of knowing the latest science-backed training and nutrition advice, but 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.

MASS does the hard work for you.

We break down the latest research in plain English, so you can apply it to your training and nutrition ASAP.

You can be an expert in strength and physique sport without wasting any more time, energy, or money sifting through studies.

An essential part of interpreting research is figuring out how new findings fit into the understanding of an entire body of scientific literature on the topic. As the scientific community learns new things and discards old practices, we’ll help you stay abreast so you can grow and evolve without chasing your tail with every new fad or staying stuck in your ways and being bound to tradition.

Learn in whatever style suits you.

We have two types of articles (comprehensive and briefs), audio episodes, video lectures, plus tons of infographics in each issue.

Escape the confusing jargon of scientific literature with our concise, easy-to-understand writing.

We’ll tell you what you need to know while cutting out most of the jargon, acronyms, and confusing language so often found in studies. With precise and pithy writing, interpreting research is simple and accessible to all.

Nerd out, if that’s the kind of thing you’re into.

As an added benefit, our interpretation will aid your ability to dissect additional research which you choose to examine on your own. By reading our monthly reviews, your critical thinking and ability to decipher research will be enhanced to further benefit your capability to improve your training.

"The level of information is astounding, the topics covered are perfect, the interpretations of the research are applicable, and the writing is the perfect combination of articulate and understandable. ... If you want your training, nutrition and coaching to all be based on the latest reliable science, then now you can do so by have the MASS team do all the work for you!"
Danny Lennon
MSc. Nutrition Science. Founder & Head of Content Production at Sigma Nutrition
"Keeping up with research that is relevant to a professional powerlifting coach is a huge task. And if you're a coach, you likely don't have the time (or let's be honest the skillset) to do all of this yourself. MASS is not just interesting to me as a fan of iron sports training. It helps me to be a better coach than I'd otherwise be."
Mike Tuchscherer
World Champion powerlifter, founder of Reactive Training Systems
"MASS is one of the best resources for fitness enthusiasts as well as professionals for reliable, science-based information in easy-to-understand summaries. MASS does the heavy lifting, making it easy for coaches and athletes to reference the information to influence the greater good of the fitness community."
Katie Anne Rutherford

Honestly, the value is pretty insane.

Our MASS archive is going to be a treasure trove for you if you’re looking for up-to-date, evidence-based advice or commentary on programming, nutrition, supplements, recovery, sports psychology, biomechanics, muscle physiology, and more.

And with an easily searchable, meticulously categorized member website, finding articles and videos on the topics you’re interested in will be a breeze.

One subscriber named Luis said MASS has become the “library of evidence-based research” for his consulting and coaching business.

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 6 articles, 5+ Research Briefs, 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.

Here are a few other things that make us different:

MASS is a great monthly value. Each monthly issue of MASS is longer than those from most other research reviews (ours are normally 100+ pages). You get more content per dollar you spend.

Every article published in MASS is rigorously peer reviewed. MASS is created by some of the smartest people in the industry. Each article is peer reviewed by all other members, meaning you get more nuanced, well-rounded information. We also include audio conversations discussing the findings of each study we review.

MASS has a sleek, professional design. MASS is beautifully designed and easy to read. Every issue contains around 40 infographics to help you interpret and understand each study quickly and easily.

You have the option to skim or dive deep. We include summaries and key takeaways for each study we review, so you can easily skim everything, then dive deep into the topics that interest you.

We include audio episodes every month. Prefer to listen? We record short audio conversations about each article we review, so you have options for how to get the information.

Every issue of MASS includes unique video content. Every monthly issue of MASS also contains two video presentations that aim to give you a broader, concept review of some of the most important topics in strength, physique, and nutrition research.

We’re never late. We’ve published a new issue every month for several years now. Every single issue has been released right on schedule. On the first of every month, you’ll have MASS in your inbox – guaranteed.

Absolutely. When you subscribe, we’ll send you a receipt email with a link to a page where you can manage your subscription. You can unsubscribe at any time quickly and easily.

You only need to enter your payment information once, and then we’ll automatically bill you on the same date you signed up. For example, if you choose the monthly subscription and purchase on April 30, we’ll bill you May 30 for your next month.

  • Competitors in any strength or physique sport
  • Coaches who work with clients in any strength or physique sport
  • Trainers whose clients are primarily interested in gaining muscle, losing fat, or getting stronger
  • Nerdy fitness enthusiasts

We’ll send out a brand new issue of MASS on the first of every month via email. We’ll also post the new issue in the membership website you have access to so you can easily download and read from there, too.

Yearly and lifetime subscriptions come with a guarantee that if we ever close up shop and stop making MASS (though there are certainly no plans to do so in the future), you’ll never pay more than what you otherwise would have paid for a monthly subscription.
