hahaha, dude, u got me confused now.
im pretty sure that i just use the same grip width as my flat bench press. like 2 or so feet apart?
def. dont have the bar touch ur shins, u want it close, but not that close. just close enough so that u get a good stretch with the negative motion. dont let the weights slam off the floor each time u lower it. it should always be controlled. then explode up. when raising the weight, u should use ur lower back, hamstrings, upper traps, etc.
push up with ur whole foot.
some people just take longer to get the form down, dont worry itll come to u. but i def would stress that u need to practice proper form cuz u will bust ur $hit up pretty good.
