Does anyone here know if wearing weighted handgrips (or boxing gloves) while doing kickboxing will aggrivate shoulder tendonitis? I have been thinking of buying the weighted gloves to add a little umph to some of my kickboxing workouts, but I wasn't sure if that was a good idea given the speed of the movments (punches) and the fact that I have chronic tendonitis in my shoulders (from swimming not kickboxing). I just don't want to do something that will make it worse.
