Many with Left side tighter than right?

Interesting,as this is precisely what I was referring to when I mentioned the Force Time Curve in response to your question about load.
Everything related to the ARPwave and POVsport technologies and to the System which backs them up is related to velocity,and maintains velocity as the mainframe of the whole System (precisely as speed is in CFTS).

Now my question for you becomes: starting from where you mention above,is progressing to “harder exercises” and loads really…a progression? What is your end goal in doing that? Can that goal-whatever it may be - be accomplished without such a “progression”?

Also: wouldn’t putting (and keeping) the whole system in a situation where it HAS TO respond maximally and as a whole,without even allowing the possibility of “some muscles not responding” beforehand,be a more efficient strategy ?
