Episode 25 - Iron Culture Epilogue

Does this title make you puke a little in your mouth?If so, you should definitely listen. In this episode we jam on…For trainers or health professionals that struggle with the idea of selling what’s the play?If someone’s business is location dependent or geogeaphically limited what should they focus on to gain new customers? Is it even worth it to spend time on social media for business purposes?According to SmallBizTrends 83% of new business comes from word of mouth referrals. How key are word of mouth referrals in this new online fitness business space?The power of polarization and why no one cares about tooth brushes. If you’re for everyone you’re for no one. How key is defining your client avatar?If our goal is getting more clients why do so many of trainers try to look cool in front of our fitness friends and clients with fancy vocab and arguing about the minutia when we should be offering solutions to problems our current and potential clients care about?How has COVID changed the fitness landscape? Is the best play to follow the masses and start offering online programming? A subscription monthly newsletter? Razorblades! Or would we be better off swimming the other direction, thinking outside the box, and opening microgyms or buying a u-haul and filling it with equipment and driving around town?Or maybe we all just start mowing lawns?How do you avoid burn out working online?What still gets you excited about this fitness and nutrition space?

Episode 24 with Kyle Dobbs - The Business of Fitness

In fitness and nutrition, minute details can drive us apart, but looking practically at this beautifully intricate question of getting more bigger can help bring us together. Metabolic stress is masochistically fun and mechanistically complicated.And yes we don't really know if these strategies will have an independent effect outside of the mechanotransduction model. BUT around 30-40% of 1RM is very likely going to equate on a set volume basis to higher loads in terms of hypertrophy so you don't have much to lose outside of weight on the bar in lower rep ranges and may potentially have a lot to gain by differentiating your training stimulus. Therefore, if you are extremely "risk" averse and want to only train in the muscular tension bean counter rep and weight model go for it! If you want to NOT even "waste" some portion of your training year experimenting, having fun, and playing with different strategies you can be very confident that you will not shrivel up and die...in fact at the very least you may even be able to build a better pump and you may potentiate your ability to drive more adaptation via the mechanotransduction model. References:https://pubmed.ncbi.nlm.nih.gov/29564...https://www.ncbi.nlm.nih.gov/pmc/arti...  Coach Kassem of N1 Education also has some fantastic charts and tools that he uses to break this complex subject down into logical pieces and fun practical applications.

Episode 23 with Kassem Hanson - Metabolic Stress as a Potentiator of Hypertrophic Gains

This episode is a banger and we get right into it. You may want to read through the questions and the Trello board first before listening. Ryan and I are just dumb enough on this topic to ask the right questions. Trello Board provided by Evan. https://trello.com/b/nir9R2O0/bro-res...Outline of the Episode:What is wrong with the classic reductionistic view of energy system training? Ie: less than 10s=phosphagen system; 10s-2mins=glycolytic, 2mins=oxidative what is really happening?What is the true role of lactate? Why do you think Shulman’s glycogen shunt hypothesis didn’t go viral in the early 2000s? It’s hardly cited which is quite odd to me. Is this conventional mode view of energy systems even helpful to use for programming purposes? How does this new model change how you train your endurance athletes?Hypertrophy “athletes”?How do you respond to those who NIRS without doppler measurements of blood flow is not very useful and NIRS is may only be getting superficial readings?There seems to be a push recently to avoid “glycolytic” training as it is proposed to be more “damaging” and less adaptive when compared alactic and aerobic methods….thoughts? Thoughts on why some Crossfitters get huge and how their limitations may explain their hugeness A case for local hypoxic (BFR) training for hypertrophyBjorsen, 2019--Type 1 fiber hypertrophy w occlusion training.

Episode 21 with Jeb Johnston and Dean Guedo - How to be an Ethical FitFluencer

Or is the squat a decent exercise to develop the quads and glutes until it’s not?What is the muscular limiter for the barbell squat? Is it even a muscle?Episode 20 Notes “From these data, it is unclear if strengthening a single muscle group (e.g., knee extensors) would increase squat strength, as the strength of one muscle group does not appear to relate more strongly to squat strength than another…Net joint moments observed during the squat do not approach 100% of what each joint can produce in isolation…The relationship between individual joint strength and multi-joint strength may be highly nonlinear and paradoxical, owing to the increased degrees of freedom of multi-joint movements…Humans may be less than the sum of their parts when it comes to multijoint force production”Vigotsky et al. 2018It seems like counter to what people think that by putting the barbell further away from the center of mass you are probably allowing for a more upright torso…until you aren’t. Meaning we actually see more and more erector spinae activity as you move the bar further out so the likely limiter here is just your ability to hold the position under increased fatigue and loading. https://journals.lww.com/nsca-jscr/Fu... and we probably can’t trust our eyes here for telling when people lose lumbar “neutrality” anyways.https://www.ncbi.nlm.nih.gov/pubmed/2...The glutes aren’t really working much in the bottom of the squat (the hardest part of the lift) in their lengthened position…it looks like that is primarily adductor magnus. So the glutes really wouldn’t be the limiter to extend the hip ever in the squat and wouldn’t even be used much until after 90 degrees and their force output above 90 is likely way more than anything we could put on the bar anyways. https://www.ncbi.nlm.nih.gov/pubmed/3...https://www.ncbi.nlm.nih.gov/pmc/arti...https://www.ncbi.nlm.nih.gov/pmc/arti...https://www.researchgate.net/publicat...https://www.ncbi.nlm.nih.gov/pubmed/2...Could the muscular limiter in a barbell squat variant ever really be the quads?We generally see people tip forward as they start to fatigue out later in a set. Regardless of

Episode 20 with Kassem Hanson - Is The Squat the Best Exercise For Quad Hypertrophy?

Is 9,8,8,8 across four sets of your 10 rep max better than 10,7,6,5?If so I know at least one thing the difference is not going to show up in an 8-week study on recreationally "trained" subjects.I also don’t think you would see a difference in hypertrophy at even 16 weeks in highly trained individuals...you might see a significant difference in dropouts or injuries, but that is just conjecture on my part.But, I still think the majority of your training on compound lifts should be done in this manner. On isolation lifts you probably have more leeway to break out the fancy shit.Let’s face it, you can always do more volume. You can drop the reps and/or drop the weight and in theory train forever accumulating all the "effective" sets ever. But, there has to be a point where it just becomes junk reps and junk volume, where what you are doing is potentially worse than nothing...blasting up your RPE in the name of increased recovery time.We also don’t really know if you equate hard sets if actual work volume completed is critical or if so how critical, but given the research on strength and exercise order, it likely has some implications over the long-term in highly trained lifters.Therefore, we at BroResearch are willing to take the stance on albeit tumultuous ground that if you are training with the primary goal of increasing muscular tension it is likely best to structure your training in a way where you have the least amount of rep drop-offs at the highest training weight for your target rep range (especially on multi-joint high-skill movements).*It is worth stating that this total work volume over the session may not matter and likely none of this matters for untrained subjects because they have more or less cooked the system at one or two sets closish to failure per muscle group. References for Episode 19https://pubmed.ncbi.nlm.nih.gov/28965198/https://www.ncbi.nlm.nih.gov/pubmed/29112055https://journals.physiology.org/doi/full/10.1152/japplphysiol.00775.2016https://www.ncbi.nlm.nih.gov/pubmed/26308090https://www.ncbi.nlm.nih.gov/pubmed/14715039https://www.ncbi.nlm.nih.gov/pubmed/22510801https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4763829/https://www.ncbi.nlm.nih.gov/pubmed/23438229https://www.tandfonline.com/doi/full/10.1080/17461391.2020.1733672https://pubmed.ncbi.nlm.nih.gov/31188644/https://www.ncbi.nlm.nih.gov/pubmed/27941492https://www.ncbi.nlm.nih.gov/pubmed/30248269https://www.strongerbyscience.com/effective-reps/

Episode 19 - Does Work Output Even Matter?

In this Episode of Bro Research Radio Ryan and I jump into the nuances of Exercise Order and definitively answer exactly zero of the following questions.·         Bench before Squat or Squat before Bench? ·         Training to Failure vs. Not?·         Compound before Single Joint Exercises or Single Joint before Compound Exercises?·         Exercise Order by Priority?·         Dumb lifts second?·         Antagonist Supersets. Means to increase rest without while decreasing overall workout time without sacrificing productive volume . If you minimize rest you will likely sacrifice reps on the back end.  ·         What if you don’t have a life and thus don’t have to choose?

Episode 17 - Metabolic Stress

In this Episode Tommy and Ben dive into a recently published paper on glucose disposal post-exercise and finish up with a discussion on the fallacy of simple predeterministic stories based on genetics and Tommy's in review paper on the actual phenotypic expression of certain popular geneotypes in the healthosphere. For more reading on this topic the links to the majority of the mentioned studies are below. https://www.ncbi.nlm.nih.gov/pubmed/31033904https://www.ncbi.nlm.nih.gov/pubmed/31082986https://www.ncbi.nlm.nih.gov/pubmed/30239554

Episode 16 with Dr. Tommy Wood - Glucose Disposal and Environment vs. Genetics

In this Episode, Ryan, Pat, and I continue the deep dive discussion revolved around delineating the Squat and the Deadlift. In the next hour we dig into the following questions. • What are your costs and benefits involved in maintaining a counternutated sacrum while squatting? • What are the other most common errors you see with big patterns and what are the potential objective benefits of fixing them if you don’t have any pain and are currently performing well?• Do you want to more stretch in the hamstrings on the RDL? What do you want people to feel on this exercise?• If you didnt grow up in the era you grew up in would you even use the barbell?• What the deal with the air?  Give us the deets. • Eccentric overloading?• Drop sets?• Favorite Keiser machine?• How do you drive adherence in one of the most hedonic and novelty seeking populations out there?

Episode 15 with Dr. Pat Davidson - The Squat and The Deadlift

In this Episode of Bro Research Radio Ryan and I discuss the nuanced topic of Training Frequency and Recoverability. You can’t really think of training frequency in a vacuum and training frequency is normally the best means to add volume if you are looking to do it in a manner that minimized per session and program RPE. The more advanced you are, the more often you can train the better (to a hypothetical point, but likely not a logistical one), but to me this has more to do with your life, your personal preference, and your per session work capacity than training frequency itself. For example, take the three volume equated training programs below: a 4 day Full Body, a 4 day Upper/Lower Split, and a 6 day Upper/Lower Split. See here https://www.dropbox.com/sh/7vqxek1xngrk4i4/AADpEuDp2sczx8VWkHjJhpgca?dl=0I would make the argument that the 4 day Upper/Lower split will result in the best pumps, but possibly a lot more junk volume than the 4 day Full Body. The 6 day Upper/Lower looks more attractive to me personally than the other two, but I like training every day as it anchors and supports my daily activities. However, imagine you took that same 4 day Full Body and broke it into two-a-days and 8 training sessions. Bangerang, I would say that hands down that would be the winner if you are trying to maximize muscular tension and effective reps, BUT you are now training 8 times a week.Check out the episode, we digress a bit but we do cover…• Training Frequency if you are just starting lifting vs. an advanced trainee. • Advanced trainees may have muscle groups with high training ages and muscle groups with lower training ages. • How long does it take highly trained subjects to recover from different stimuli? Does recovery = adaptability? • Training frequency less important than overall training volume BUT allows one to dissipate the training load over the week and thus reduce per session RPE and overall program RPE and likely increase productive volume across the training career. • High training frequency programs will likely need to be heavy in rotating accessory work to prevent over-use injuries. • Acute to chronic load ratios and maintaining high chronic training volumes being protective against injury. • The upcoming acute study design and where it will fit into the current body of literature.Here are some of the studies we reviewed during this episode:https://www.ncbi.nlm.nih.gov/pubmed/28716692  https://www.ncbi.nlm.nih.gov/pubmed/10929214 https://www.ncbi.nlm.nih.gov/pubmed/30621334 https://www.ncbi.nlm.nih.gov/pubmed/28965198 https://www.ncbi.nlm.nih.gov/pubmed/30779596

Episode 14 - Training Frequency and Recoverability

In this this episode, Ryan and I talk about... Why food volume matters. Humans evolutionarily not adapted to higher density foods especially fat+ carb hyperpalatable hyper ED combinations. Humans are inaccurate in their judgments of how many kcals high ED food have (above 1.5 kcal/g). Children show a linear relationship between food preference and energy density. Over a five day period a spontaneous decrease or increase in kcals with ad-lib intake of low or high ED foods in childrenRCTs generally show better weight loss and weight maintenance and less hunger with lower energy density diets. Not the end all be all, but makes a lot of mechanistic sense especially for weight regain. Low ED pre-loads are a viable strategy to try while dieting. We also discuss confounders of food volume and how they matter in research, but not so much in real lifeNutrient Density/Diet QualityEating timeWater contentFiberSugarFatDoes this food volume adaptation potentially go hypothetically go both ways?!If you increase your food volume and do you now eat more high energy dense food?Food volume, food quality, and weight gainSkeleton of high quality meals of real food and then use higher ED foods to meet increased kcal needs. 

Episode 13 - All Things FOOD Volume

In this Episode Ryan, Ethan, and I talk shop on the nuances surrounding some of the more technical issues in the training world. We don't give concrete answers and we all have different opinions, but if you love the extremely important yet granular details of the weight room and programming you will love this conversation. Tracking Volume and RPE/RIR1 to 1 for agonists and synergists? Sets to a 6 RPE vs. sets to a 9 RPE?Accounting for different strength curves in exercise selection and volume tracking?Accounting for position in exercise selection and volume tracking?Progressing Volume Do we oscillate volume or do we ride it until it is broke and then move up or deload?Can we just play the tension game for decades and work around and work to prevent over-use injuries or would we be better off utilizing different macrocycles within the training year?Utilizing strength and loading as the primary driver of volume?
