chris, where are you going to study? also, you can go into any local fitness store and get the straps you need....like fitness experience or american home fitness.

voodoo, it's great that you aren't actually holding anything in your hand. attaching it at the wrist is key. nice job. where are you going to attach the other end? also, did you get a strap hat will allow you to attach it to your bicep/elbow? that will work the shoulder more. but either one is good. Personally, I do both... ie, attach at the wrist and then at the elbow for full effect. one more thing, for more power, double or tripple up on the cord. just make sure you do it plyometrically to work the fast twitch muscles. that'll give you the power and speed you need.
