i think it can work cuz like krzysoulja sed you can feel your muscles contracting just thinking about handling. I tried it in church with shooting and it was pretty crazy. thisll work especially well with people with injuries.also i dont know why people are putting this down so much, cuz nba players do this as much as they can. Phil Jackson hired a psychologist when he was with the bulls just to get them to a mental workout. so if ure saying this isnt important your just ignorant.
