Man this one has my forearms really sore! My question is this if you practice this exercise how many months would take to reach the speeds this young man has playing 16th notes at 180bpm.
I'm doing it really slow at like 80 bpm and that's comfortable to me mainly because I'm trying to clean up my doubles,I recently learned it's all about the fingers the wrist will conk out at a certain speed alone. But I'm wonder just how long it took him to get these chops?
