I never get to train long enough

[fiddlesticks]

It’s not, the body has a natural fail safe if you will to prevent injury. For the average senditary joe,They would be lucky to elicit more than 85-90% of the full muscles potential. With training and psychology then a person can get closer to 90-93% ish. The numbers very in the literature somewhat. That’s why Sports Psycology got so big in the 90’s and early 2000’s as everyone was trying to “hack the system” and get more and more motor unit recruitment out of athletic movements.

Interestingly, there are pharmacological agents that help with that. Caffeine being the most commonly know and of course PCP making people “super human” strong. Most of the system resistance has to do with the nervous system holding back recruitment of all motor units. I had a lab partner who’s thesis work was using things like Russian stim to increase power output on anaerobic tests like the Wingate. Or one rep max on knee extension and so on.

David Archiletta (spelling?) had a cool draft day video years ago with him working with his private strength coach using Russian stim or variants of it.

What I meant was It is possible to utilize the muscle more in certain positions, e.g bicep curl bottom portion is much harder than top. You are always able to perform 3-5 baby reps once the full rom reps have been complete
