What r/AdvancedFitness is:

  • A place to discuss fitness, health, nutrition, and training programs beyond the beginner or introductory stages.
  • A place for you to ask questions and learn from others on the above topics.
  • A gathering place for enthusiasts, athletes, researchers, and everyone in between to discuss shared interests.
  • Somewhere where intelligent discourse and thoughtful questions are the norm, not the exception.

What r/AdvancedFitness isn't:

  • A place for you to spam your crappy products.
  • A sub that will dispense medical advice. If you have a condition that is affecting your lifts, you need to talk to a medical professional.
  • AF is not a place where information will be spoon fed. If you want a 'tl;dr' or 'ELI5' you're in the wrong place.
  • This is not a place for memes, rage comics, image macros, or things that provide no value.
  • This is not a place to post threads where the only discussion to be had is congratulating the OP.

Concerns with cryotherapy and fractured bones healing? [af]

Hey all, does anybody out there have any knowledge or experience on if cryotherapy can negatively impact bone growth?

Background: I was in a serious accident 8 months ago that resulted in a shattered femur, stress fractures, torn labrum, multiple partial tears, and lots of nerve / soft tissue damage. I am at the point where I’m cleared to start weight bearing again (for the 3rd attempt) and my muscle recovery is finally starting to go well enough I can actually do basic lifts like quad ext on the machines again.

One thing that has drastically helped me in previous (non broken bone) injuries is working cryo into my routine to help with pain management and inflation, especially as I pushed the PT. I would like to start back up again, but my femur is still in 2 pieces (with about an inch gap) and I’m not sure if there would be negative consequences. Unfortunately I am still fairly limited in what I can do myself (foam rolling, massage gun, etc.).

Thanks in advance!! I couldn’t find any real good information on the internet and the guys at any of the cryo places I have called really don’t have any idea.

[AF] Key Points from Chris Williamson’s Podcast: Exercise Scientist’s Masterclass On Building Muscle - Dr Mike Israetel

Recently found a popular episode about Exercise on Chris’ channel. So, I wanted to share some of the best takeaways I found. Hopefully, you will find them helpful if you did see the episode but forgot or simply never saw the episode.

You can view a full summary here.

Biggest Mistakes of Training for Muscle Growth 00:57

  • Lack of consistency is the biggest mistake people make when training for muscle growth.
  • Consistency is important, but it's not the only factor.
  • If you're going to be consistent, you might as well do it well.
  • Optimizing on the margins is important when you're committing a lot of time to something.

If Mike Could Only Keep 10 Exercises 13:04

  • Dr. Mike Israetel, an exercise scientist, recommends 10 exercises for effective muscle building.
  • The exercises target different muscle groups:
    • High bar squats for quadriceps, adductors, and glutes.
    • Overhead barbell press for midline bracing and overall strength.
    • Barbell skull crushers for triceps development.
    • Overhand chin-ups for back muscles.
    • Barbell bent rows from a deficit for hamstrings, spinal erectors, and glutes.
    • Stiff-legged deadlifts for hamstrings.
    • Cambered bar bench press for chest development.
    • Incline cambered bar bench press for further chest development.
  • Dr. Israetel suggests a full-body workout routine with these exercises, emphasizing personal motivation and enjoyment.

Is Motivation Scientifically Reliable? 01:45:15

  • Motivation, which includes inspiration, motivation, habit, willpower, and passion, is essential for going to the gym.
  • To increase motivation, set clear and achievable goals, surround yourself with positive influences, make the gym easily accessible, and choose exercises you enjoy.
  • Consistency is key, so develop a habit of going to the gym regularly, even for short workouts.
  • Gradually increase the intensity and duration of your workouts as you become more comfortable and experienced.
  • Ensure progressive overload by increasing weights or reps to promote muscle growth.
  • Assess your recovery status and adjust training intensity accordingly.
  • Prioritize sleep (6-9 hours per night) and ensure adequate nutrition to support muscle growth and recovery.
  • Follow a well-structured training program that includes progressive overload, proper recovery, and sufficient sleep.
  • Muscle building requires a combination of progressive overload, adequate nutrition, and sufficient rest.

[af] How valid is the stimulating reps model?

The stimulating reps model has become very popular especially in TikTok with fitfluencers stating quite adamantly that it aligns with what we know about physiology.

I believed it true but I’ve had my doubts about it. It doesn’t help that it’s biggest proponents either regrugitate it or are unwilling to properly engage with its criticisms.

Greg Nuckols pointed out how motor unit firing rates decrease as a result of fatigue with greater decrease with greater set durations. Therefore single fibre tension as we approach failure will be significantly lower in low-load compared to high-load conditions.

My other issue is that high-load training produces greater voluntary activation increases than low load training yet we observe the same muscle growth despite exposing more high threshold motor units to stimulus in the high-load conditions.

Moreover if you look at measurements of peak force in sets towards failure you observe a decrease in peak force (https://pmc.ncbi.nlm.nih.gov/articles/PMC11057621/) with an increase in sEmg(which roughly correlated with motor unit recruitment). So the assertion that single-fibre tension increases with closer proximity to muscular failure because of slowing contraction speed ignores the effect that fatigue has on force production.

With that being said, what then happens that makes reps close to failure more stimulative than reps before ? For the above reasons I don’t think we can make the claim that it’s because of higher single fibre tension with slowing contraction speeds.
