much slower than someone observing you. is that what they said in terms of superfast travel, i wasnt really paying attention
i equate contraction with higher speed of vibration "i guess could be the opposite)
ok
now a speaker likes to raise its amplitude by having another speaker
so what if we could raise the amplitude (lack of words) of our workout with sound
like if you are trembling , super flexing really hard, that can be amplified with a low tone on a music constant keyboard tone., it would raise the volume of the sound your muscles are making . muscles do make sound, of course everything is 'sound' but the type of sound your muscles make when they are flexing very hard could be amplified by an outside source like with a musical instrument
