Get information specifically curated for strength sport athletes, coaches, and enthusiasts.

Save the time and money necessary to read 1,000+ studies per month.
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.
But...
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.
However...
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 100+ 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 a monthly digest to help people like you bring their A game.
- Extremely relevant and focused. Our focus is narrower than other research reviews, focusing solely on strength and physique athletes, coaches, and enthusiasts. This means that every month, we’ll review only the research that’s the most relevant for you and your results.
- Application is dead simple. Each article begins with a bulleted list of key points and ends with another list of applications and takeaways. Both aim to tell you exactly what the newest research means for you training or nutrition so you can start applying the latest science right away.
- Meticulously researched and curated. Every month, we sift through 53 journals (and adding more all the time) and roughly 1,000 articles, identifying the research that’s essential for you or your clients. The result is a review full of the highest-quality, most relevant content, with none of the false positives or ill-advised fads.
- Easy-to-understand writing that skips the jargon. We’ll tell you what you need to know without using the jargon, acronyms, and confusing language so often found in studies. With precise and pithy writing, interpreting research is simple and accessible to all.
- Findings put into context. 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.
- Additional resources for subscribers who want to go more in depth. 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.

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.
Can I unsubscribe at any time?

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

Customer Reviews
You're doing fantastic, and I love the summaries. I have progressively less time to dedicate to the field, and I need the best bang for the buck. With MASS I can be assured that I'm not missing anything while having top-notch content every time.
Tiago
We all want to say we're "evidence-based," but it's rare to have the time (or the abilities) to stay up to date on the vast amount of research being done in the field of strength and physique sports. Fortunately, there's a service that does that for us: MASS. Each month, Greg, Mike, and Eric put out material that is thoughtful, insightful, and easy to digest. The "A" in MASS stands for "applications," and the content lives up to the name; every single article has practical takeaways from the study being discussed so you have an easy-to-reference guide on how to apply the research to yourself and your clients.
Daniel
Furthermore, when you subscribe, you are supporting a group of people who genuinely care about the education of trainers and athletes, as evidenced by their active participation in the private MASS Facebook group. I have reached out to more than one of the authors to follow-up and/or clarify points in their writing so that I can use their ideas in the context of my own work, and every time, I have been blown away by the generosity they display with their time and expertise. This is a good group of people who really go the "extra mile" for their clientele.
If you're on the fence about subscribing to MASS, I get it: there are countless "educational opportunities" being marketed to trainers, and it can feel like everyone wants to take your money. This one, however, is one of the few that are truly worth the investment. Sign up for MASS and be a better, more thoughtful trainer (or athlete) for it.
As a trainer and coach, I honestly can’t look past this as the number 1 resource for staying up to date with the current research, topics and trends. The info is provided in formats that cater to all learning styles. From the written articles, through to the round tables and video lectures, MASS is a resource every coach should be subscribing to.
Sean
As an owner of a consulting and coaching venture where we coach +400 clients a month, I can surely tell you that your resources are on our basic “library” of evidence based research.
Luis
We use your information to continually improve and review our protocols and thus, deliver the best results to our clients.
My last 6 months lifting have been my most productive ever, and MASS has played a huge role in that.
Alex
Strength and Conditioning is an interesting field because personal experience and academic research need to be used together to develop the best methods. MASS provides an invaluable resource; it is rare to find experts with tens of thousands of hours of practical experience (coaching and their own training) AND the academic background to evaluate the latest research. The practical recommendations that come out of that combination can help the beginner and the expert. If you want to elevate the level of your coaching or training you would be doing yourself a disservice by ignoring MASS.
Steven
At 56 years of age and raised on the bro science mantra of “No Pain No Gain” which included rupturing both bicep tendons (a year apart) and a torn rotator cuff I decided I needed a smarter approach. I’ve since listened to every single 3DMJ podcast twice, read both of Eric’s pyramid books and joined MASS a couple of months ago and have since devoured everything in every issue and eagerly await the next issue. Now at 59, I’m 13 weeks away from my first contest, OCB Classic Physique in the Masters 40 class but far more important, I feel like I’m 40 and ready for the 2nd half of my life! MASS is the icing on the cake!
Al
As someone who has been geeking out about training & nutrition science for years & now pursuing a career path in doing what you guys do myself, MASS is one of the extremely rare things I'm more than happy to spend money on because it provides me an unprecedented condensed source of exactly the content I want to bite into from some of the people I regard most highly & hope to call colleagues in the future.
Tanya
Doing extraordinary things for people like me who are still in uni. Helps keep up to date, especially since unis often teach relics.. oh and it's easy to digest.
L
I’m very happy and I love the audios became I don’t always have time to sit down and read a really digest everything. I love how the articles are categorized too
Steven
MASS put me on a whole new level of knowledge. I’m just a software engineer sitting down 8hrs a day on a chair, decided to take action and be active, I became a fitness enthousiaste, now I’m a health obsessed
Anas🤷🏻♂️ training smart, and having real strength and fitness goals. That’s what MASS have done for me. Started my fitness journey 2 years a go at the age of 31. I needed this kind of knowledge to make up for the time lost ... and by the way guys having MASS shouted out by Stan Efferding... is just mind blowing! Mark BELL ... i mean the work you do is priceless ! Thank you from the bottom of my heart
The biggest source of utility from mass to me has been the video series and whenever in the study reviews, the relevance to a bigger picture is drawn.
Kim
The video series however have been very helpful and almost worth the sub alone. Definitely keep, or even expand, that feature!
I love MASS, honestly just gives me the new research in the field and I love the summaries, because when i’m pressed for time I can just read the summary and understand the findings of the research
Jordan
I am fairly new to the MASS world, but I will share my experience so far.
Brandon
In terms of format, I appreciate the use of articles in conjunction with the audio roundtables. This is my first research review subscription so I'm not sure if others do this as well. I particularly like how the article and discussion complement each other as opposed to just being the exact same content in different formats. The videos are great additional resources due to their comprehensive nature.
One of the coolest things about MASS was the article on interpreting research. That showed a commitment to connecting people to what the research means which I would hope leads to the audience being more cautious about jumping to conclusions. It seems as if MASS is meant for us to not just be mindless consumers of content but to be an actively engaged community.
Lastly, I would say that I am so happy to finally have the one right answer to every topic on training and nutrition...just kidding! This team does a particularly outstanding job of taking research in context of all the other research that has been done on any given topic as well as presenting their anecdotal experiences with that topic. There is considerable time spent talking about both what an individual study means and the bigger picture of how it fits with other research or experiences. In addition, the team always rounds out the conversation by talking about what it means for athletes and/or coaches. These practical takeaways are ALWAYS presented in a non-binary way which shows the team's commitment to understanding.
Thank you for taking the time to produce the content in this way.
MASS is the best monthly installment coming out of my account by far! Thanks guys!
