Isn't training till failure a really bad plan? It'll cause damage that's really hard to heal from.
Training to failure is a pretty great idea for beginners and something that should be done often at any training age. Main reason being you need to take a set to within 3 reps of mechanical failure to get a proper growth stimulus. So you need to lean where the line actually is, and remind yourself often.
The vast majority of people have no idea how to push a set hard enough. That’s not my opinion btw, 80% of the people you see walking around the gym get this wrong.
Doesn’t cause any notable damage. You will be extremely sore however if you rush into it. But once you’re accustomed to it you can pretty much train a muscle every 2 or 3 days if you wanted, as long as your sleep and nutrition are on point.
Certainly agree from my experience with a personal trainer. Never got so sore working out by myself.
Training to failure doesn't increase strength or hypertrophy according to Jordan and Austin (both medical doctors) at Barbell Medicine. https://forum.barbellmedicine.com/t/training-to-failure/11792
But they do use RPE where you estimate how close you are to failure in order to perform a number of reps for that set.
If it's taking really long to heal, you're going well beyond failure. There's a heightened risk of injury, but again, that's not failure.
The bigger issue is that training to failure does less for strength or endurance. It's more about muscle size. And the benefits are seen if you train to just below failure. Actually crossing that limit is mostly meaningless, as far as your muscles are actuslly concerned.
Training to failure has its benefits, particularly in strength/weightlifting areas, overtraining can cause rhabdomyolysis and other issues but that's usually from a combination of factors like nutrition, rest, sleep, proper form etc it happens more often in HIIT exercises where someone might be training at an extreme pace
FWIW I'm just some guy who exercises, take this with a grain of salt
