Generally speaking, I think you're playing with fire in mesing with ankle/wrist weights on exercises that already high impact. If you want to develop more exploiveness in your sprinting, sprint up hill instead of using weights. Ditto aerobic running -- this is an activity that's already hard on the joints. I also wouldn't recommend doing bagwork with wrist or ankle weights, if you want more resistance consider using an elastic stretch band between your ankles (for more resistance on footwork) or one of those vests with elastic bands that attach to your hands (for more resistance on punches). Same with shadowboxing. Note that when you spar with wraps, tape, and 16 oz. gloves, you've got nearly 1.5 pounds hanging off the end of your hand anyway, so I assume you're talking about weights that are heavier than that. |
