    #11 High Efficiency Hypertrophy Training - Dr. Eric Helms

    There is a lot more to program design than linear straight sets. There is much debate on whether specialty set methods and pairings can be used to grow more muscle. A lot of this has to do with what constraints you have on training time and effort. In the right context, supersets, drop sets, paired sets, rest pause and more can be ways to get gains in less time, or more gains when time is limited. Coach Kassem has been teaching a comprehensive approach to these things at N1 for quite some time and today he sits down to discuss them with Dr. Eric Helms Eric has been using these methods to make progress as an advanced lifter and pro bodybuilder who is also constrained on time. He has a history with the methods both in practice and in the research field. The best way to keep up with Eric is to join is Research Review at https://massresearchreview.com

    #10 Dr Desouza: Are Lengthened Partial Reps Overhyped?

    In Part 2 with Dr. De Souza, we get a sneak peak into a study that hasn't been published yet, but contrasting to the "52 weekly set" paper, this one did not find higher volume to be better for hypertrophy. In the second hour, we take on the topic of lengthened partials in a bit of a debate format, where Kassem takes on the position to defend the lengthened partials, and finishes with his actual nuanced thoughts on lengthened biased training and training variability.

    #9 Dr. Desouza: Hypertrophy Studies VS Just Smashing Weights

    Part 1 of 2 with Dr. Eduardo De Souza whose lab has been doing ton's of studies on volume including the famous 52 weekly sets study. We start the discussion with a much needed preface of how confident are we actually in measuring hypertrophy outcomes. Then we progress into the validity of studies on high volume. In part 2 we will continue the discussion on volume including discussing some yet to be published work that may surprise you, and we will finish off with a debate on long muscle lengths and lengthened partials. This is where your favorite influencers and coaches get their information and inspiration.

    #8 Dr. Eric Helms - Science Communication in the Fitness Industry

    Dr Eric Helms returns for another episode of The N1 Experience. This time exercise science is on the ropes and Kassem challenges Eric to white pill him on the current state of exercise science communication. This episode really peels back the curtain on exercise science, and some of the harsh realities consumers face navigating social media and when trying to know who to trust.

    #7 "Stop Blaming Science, Bro" with Dr. Pak

    Should you trust someone because they have a PhD? Real Doctor, Dr. Pak (@dr__pak) is on to defend science and all her glory. I challenge the quality of "science-based" content, and the use of science as a marketing hype by "bad actors". What's the difference between a sports scientist and an exercise scientist, and how well do the understand the foundational science for the field or training (anatomy, biomechanics, physics etc). As a bonus we also discussed his recent publication "Optimizing Resistance Training Technique to Maximize Muscle Hypertrophy: A Narrative Review". with Dr Milo Wolf, Max Coleman, Ryan Burke, Alec Piñero, Jeff Nippard, and Brad J. Schoenfeld,

    #6 Is Exercise Science KILLING your GAINS? Or "science-based" content creators? with Alexander Bromley

    Recently Alex published a video titled "Exercise Science is Killing Your Gains" This prompted a lot of discussions, one with Dr Pak and Dr Milo Wolf that "went nowhere" - to quote Eric Helms, as well as Eric's own reaction on Iron culture Still I think a lot of people, myself included were left wanting to dig deeper into the rise of anti-science sentiments in the fitness community while simultaneously there is more so called "science-based" content popping up than ever. So I sat down with Alex, Dr Pak, and Dr Helms for about 2 hours each to peel back the layers on this topic, and at the end I will give you final thoughts. If you are like me and you enjoy these somewhat philosophical conversations about our industry, and how to navigate it and make it better, then you'll get value out of the next hours of discussion.

    #4 Squats vs Hip Thrust Part II

    On this Episode of the N1 Experience Kassem sits down with Daniel Plotkin, the lead author of the 2023 study comparing the squat vs the hip thrust for glute hypertrophy. Also on todays episode is Milo Wolf, who is at the forefront of the research on range of motion for hypertrophy. Together they give a much needed breakdown of the current research on glute training and what if anything this new study changes in how they approach programming for glute growth.
