How hard do I pull
Pretty simple question without getting into a great discussion. How hard on a level of 1-10 do you pull during a stretch, and is any stretch over 60 seconds just going to end up hurting your unit? Is it better to stretch for 30 seconds than 60? After doing a full rotation of stretches, how long should you wait before doing another set of left,right,up,down,out, all around? Also, when I try to fowfer stretch where you hold under your butt, I feel something, like a vein maybe, start to hurt in my scrotum :O
