Another great Podcast on @ExerciseScience this week . Featuring Brad Schoenfeld on some of the major myths still floating around the gym . At 40 minutes its perfect length for anyone trying to do 20 minutes of resistance training followed up with 20 minutes of HIIT

Do you need to go to failure? Our experience - with 1000s of clients pace.mcmaster.ca/ - is no! Consistency of practice (regular attendance) and knowing what goals are important are far bigger levers. journals.lww.com/acsm-esm/fu…

I’m not saying you have to go to failure for gains. Quite the opposite. But you have to go there to understand what ā€œRIRā€ is!

High effort IMO Drew. People learn quite quickly how to do it with the 'intensity' that equates quite quickly to 1-3 RIR

#1 in the list: adherence. "Intensity" here means effort, not heavy load. The review is clear that hypertrophy "can be obtained across a wide range of loads," and the recent ACSM Position Stand found growth wasn't meaningfully affected by load (30% to 100% 1RM) or by training to failure. Volume and consistency mattered more. So how should most people gauge it? By effort, not a %1RM target: take sets close to failure (about 1 to 3 reps in reserve, or use an RPE scale), pick any load you can train hard with, and add volume over time. The message isn't "lift heavy, or it doesn't count," it's "show up and train with good effort."
Replying to @mackinprof
From your recent review, intensity matters, not just going to the gym and moving some weights. How do you suggest the 95% gauge intensity? pmc.ncbi.nlm.nih.gov/article…

My dad in 2012 at Omaha Beach cemetery honoring his fallen comrades. My dad landed with them - and three years ago died and joined them. Taking the trip with my dad in 2012 was a highlight. Thanks to the #greatestgeneration

BIG picture... Most people don't go to the gym. Decent message, not quite accurate, but I love that we're talking about lifting! journals.lww.com/acsm-msse/f… "Deviating from previous guidelines, we propose that individualizing programs to increase RT participation is, from our perspective, more important than conforming to specific RTx criteria." "Completing sets to fatigue (momentary muscular failure) does not enhance gains in strength, hypertrophy, and power, and so is not necessary for benefits to occur."
Most people I see in the gym miss this, leaving gains on the table.

"Zach you should have a debate with someone about low vs high carb" I am more than happy to have this converastion with anyone who can grant this one point. We both need to be able to assume that if we are discussing world class performance at events like the marathon, cycling, or Olympic distance endurance (essentially endurance competitions performed above aerobic threshold) we agree that if an approach works for performance improvement, or is neutral to other approaches, and is stress tested with these groups, it will show up on competitive podiums over time. That is so important because it controls for variables we cannot measure in a lab. It is the ultimate outcome, because the only bias is consistant winning outcomes. The question at the center of this would be, has keto been put through that filter to the degree we can say it has been stress tested out of this system? I believe it has, and typically the people who don't, simply believe it has not been tried at the professional level, and therefor assume keto would be a novel approach yet to be stress tested by these groups. If we get to an aggreement there, we can have all sorts of other fun conversations like, what are the potential use cases for keto and low carb, what are the potential tradeoffs for low and high carb (they both have tradeoffs), who may benefit from it, and why do some people improve when they engage with these styles of eating. There are so many fun questions like this that are probably more interesting to the average person, but we cannot get to them without a proper understanding around the above.

Mechanical tension appears to be the primary driver of muscle hypertrophy. šŸ“šcurrent evidence suggests that high tension within muscle fibers is the key stimulus triggering growth. Train for progression, not soreness pmc.ncbi.nlm.nih.gov/article…

Here is the truth. If we really want to understand what influences performance either positively or negatively, we will not get there by creating a study that measures something that is basically unrecognizable compared to real world performance. Here is an example. The two sub 2 hour marathon performances. Both Sawe and Kejelcha had a team of professionals studying the demands of what they were trying to do, and testing the inputs specifically for the goal of performance. They didn't need to read up on Noakes 10g/hr claims, because they had all the performance lab data they needed to know that was a dead end for the goal they were trying to reach. They let results from the actual performance demands being studied guide their program and ended up at 100 g/hr on race day, and we saw both go sub 2 hour.
Wait wait wait, if we are going to be talking about performance claims, we should go right to the core where and when it happens, not some underpowered misrepresentation of what performance actually looks like. The strawman being attacked here is formally studying the wrong thing in the wrong context if performance is the goal.
