OC-

There are a number of other important things going on like working on fast twitch fibers and trying to get them to all fire together and to build them up so you have strength at a high/ballistic(accelerate to escape velocity)speed.I would recommend you review the stuff at setpro on overload/overspeed training and neural recruitment.Swinging heavy and light loads into the bag/tire works well.
