Failure on a 10x10 is very different from failing on a 5 rep max. Fatigue failure is good, CNS stalling is not.One will have bad effects on your recovery.
Power lifters and Olympic lifters rarely lift to failure. At one point of their cycle of course they test their limits. Bodybuilders are constantly bombarded from the HIT crowd that if they didn't rep out to failure they are wasting their time. No one can train week in and week out pushing every exercise to failure without reaching exhaustion and the need to take time off from training due to mental and physical exhaustion. Call it CNS over training or just tired it's a fact and it will happen.
Bench press, heavy = pec tearsSquats = low back injurydeadlift = low back injury.If people do the exercises sensibly they are fine, they tend not to, hence the risks.
I have different rep ranges for different muscles and exercises. Big thing I've changed in last year or so is upping volume, especially reps. Kept getting tears and injuries in 5-8 rep range despite using perfect form. I'd have to lift too heavy (for me) to feel anything in a set which lead to injuries. I've stopped counting reps in some exercises and just try to burn out muscle, machine preacher curls is one example. Why stop at 15 if you can still lift?
Going to failure in exercises with long TUT will burn you out. Powerlifters don't go to failure because of that. It has nothing to do with CNS tho, it's just your muscles getting sore and that's it.
Just pointing out that Olympic lifters and Power lifters don't do their sets to failure why do bodybuilders preach that you should all the time?
