You can correct me if I’m wrong, but no matter the rep scheme, the primary driver of muscle growth is mechanical tension. Metabolite accumulation/metabolic stress is only a byproduct of working out, and can hinder muscle growth. I’m not saying higher reps are worse, but the mechanisms in this video are explained slightly incorrectly.
Well that’s one way of looking at it, and ultimately it all comes down to progressive overload. To build muscle you must push your muscles close to failure with either more reps at the same weight, or through lifting heavier weights in the same rep range. This will give your muscles a reason to grow. So yes you’re right, time under tension is important, and that must be compensated with more sets at lower reps. And although this can be achieved with light and heavy weights, the reason I’d lean more towards heavier weights in a moderate rep range (8-12 Reps) rather than lighter weights, in a higher rep range, is that other factors such as muscle fatigue, and cardiovascular capacity make it harder for most people to push their muscles close to failure, to allow them to build muscle.
