I hear you about the touching while you are working but the safety factor? I get a bit freaked about that stuff because some dude died in a local gym doing the same thing. Be safe bro!
and one other thing, after watching your video a few times you are wiggling around quite a bit. This is not meant to break your balls but if you got a strong,set, firm base you wouldn't waste as much energy trying to balance yourself as you are pushing. Find that spot and post your feet to the floor and then try to push them through it.
But you are one strong hombre regardless. Just a thought.
