What about the old gym adage "training to failure is failing to train" - is there any physiological basis for this, or is it mental, or just a myth?

That’s a Pl/Oly mindset rather than a BB/hypertrophy mindset. Totally valid advice in the right context.

Long story short, failed reps get much more risky and problematic as the weight you’re lifting approaches your 1RM.

It holds true, but with some caveats.

Generally training to failure is completely fine for say a set of tricep extensions. Generally safe.

However, training to failure on compound lifts like a deadlift or benchpress, or involving sensitive muscles like a shoulder press, isn't.

Technique generally suffers at the point of failure. Making a habit of doing thousands of repetitions in the next decade at the point where technique fails, on an exercise that can mess up your back permanently, or your shoulders, is bad advice.

For these exercises it's better to stop 2 reps short of failure. This is more safe. Also it requires moderate recovery getting you back in the gym quicker, meaning you can compound more incremental improvements in a given training period (say 5 years).

Even then, some still cautiously go to failure to keep an understanding of what their failure point really is. You could go for a PR once or twice a month for example and go to failure, with a proper warmup, spotter etc. But purely for hypertrophy there's not really a point, this is more for strength training.

Generally people that say they train to failure mean 2 reps in reserve. Training to absolute failure on all muscles is very rare and generally advised against.

  • True. Generally, the more isolated the exercise and the smaller the muscle the "safer" it is to train-to-failure at a higher duty-cycle.

    Put another way, you can do crunches to failure every single day, but you'll want to keep some reps in the tank for squats and you'll want to plan on at least 12-24 hours of recovery between squat sessions.

not an expert, 2 years of serious lifting, but this is probably a good adage for the average person from my current understanding

training to failure puts you at higher risk of injury and there are diminishing returns as you approach your 1 rep max and/or failure

hypertrophy can happen with more reps or more weight

strength gains are usually just focused on progressive overload

though, of course, hypertrophy will happen either way and contributes to increased strength, but this seems to be further confirmation that you can gain muscle size either way

It's definitely way more nuanced than that. You have to approach exhaustion to get the body to eventually build strength. But you need to carefully time your rests/deloads and handle plateaus with more volume.

  • i definitely agree it is more nuanced! might not have communicated it well that in the context of untrained people and beginners that these guidelines will work for quite a while and most of the nuance applies much more once you get past the easy beginner gains

    for example, if someone new starts with low weight to work on proper technique and form, and adds weight each week they will continue to both get stronger and to gain muscle

    i'd imagine the average person who is casually lifting might not even get to this point and could easily spend a couple of years before really hitting a spot where the nuance is more important

  • Where could I find more information on proper set timing?

    • I like Mehdi's description over here as a good starting point:

      https://stronglifts.com/stronglifts-5x5/intermediate/#rest-p...

      Has a paper from 1976 but this seems in line with what I've read elsewhere

      basically, 2-3 minutes is probably good for most of your lifting, you could go to 5 minutes if you are doing your heaviest lift of the day

      this is also a reasonable way to make sure your workouts aren't going to take 3 hours at a time

      some people really mix max this though if they're focusing on super heavy lifts. i remember being at the gym and watching people take 8-10 minutes between sets when they were putting up 400-500lbs on a squat. they also arrived before me and weren't done when i was leaving and, i'm assuming, they were interested in powerlifting competitions

      i've actually started looking at reactive training system with mike tuchscherer who has a lot of interesting things to say about training, rest times, etc. been startin to build his stuff on RPE and fatigue percentages in to my training and it has already been super insightful and helpful

    • Honestly from a personal training/lifting coach. When I could spend serious time in the gym there’s a lot to just having someone with expertise for 30 minutes to give perspective. You can do a lot of it over video today as well.

      In general YouTube is a good resource. There are a lot of respected coaches that also produce content.

    • It ends up being personal, but you want enough time to catch your breath and be “ready” to go again, but no more.

I’ve never heard that, it’s usually the opposite- people do strip sets and the like to reach failure

Failure also taxes your nervous system and joints which don’t take as kindly to stimulus as muscles do and take longer to recover (or accumulate damage in case of joints)
