I am wondering i there're any specific benefits to pushing yourself extremely hard vs. just pushing yourself a little hard. Does pushing harder create more muscle? Make you stronger?
To simplify, imagine someone works out hard, and doesn't get injured; and now imagine someone pushes themselves EVEN harder and still doesn't get injured.
Disregarding any potential injuries or halting in the process (let's assume pushing yourself EXTREMELY HARD will still not be considered "overworking" yet).
Does pushing harder have any extra benefits vs. just pushing a little hard?
Like fighting for every next rep vs. just stopping altogether when feeling a bit tired. Is that extra push and "drive" beneficial vs. someone who may not otherwise fight or go as hard/long?
Again, assuming NEITHER one sustains injury nor impedes progress, would pushing yourself to your hardest be anymore beneficial than just going at it until feeling a little tired and then stopping?
Does pushing harder make it more likely that you'll break past plateaus? Stimulate nuclei better? Work the muscle better? Expect results sooner/later? Stimulate the nervous system in a different way?
Imagine someone on a rep curling and they have it half way up, but the force is tough and they're tired and just let it go down without exerting the force -- but another person stays halfway for 20 extra seconds, giving every bit of might and mental power they have to get it up one last time.
Would that person who killed themselves trying to fight and exert every bit of mental fortitude they have benefit from anything vs. the guy who works hard, but doesn't kill himself to get that one last rep after 10-20 tough sets of arms? Basically, does pushing yourself very hard have any upsides, assuming it's not hard enough to impede progress, but hard enough to take a mental/physical toll?
Just picture the guy that worked hard, but sweat a little -- and that other guy that worked harder, and is trembling for hours due to pushing his nervous system beyond his "comfort zone," but still doesn't impede or "overwork." I put quotes around "overwork" because people think doing extra 5 sets is overworking, when overworking means excessively exercising for prolonged periods of time and lacking in diet, sleep, or adequate "downtime." Most people never reach "overworking" because most people do not work hard enough to have a chance at getting there anyways. "Overworking" is not just pushing yourself extremely -- it's a constant, ongoing fatigue and lack of attention to your health.
