hey, i was wanting to know if anyone knew any good speed or reflex drills. also, is there anything to help me practice this? i've seen in movies where they have the wooden pole that has like arms and when you hit it it swings and comes at you but i've neve seen one in real life. if i can't find one i'm just gonna get my brother to swing at me and let me try to dodge and block but before that i would like to increase my speed/relexes. thanks alot
