I recently purchased a 4lb orange weighted jump rope through Power Systems. Wow, talk about a big disappointment. It actually hurt my wrists. Not like muscular sore, like this will hurt my wrists if I keep doing this. I did about 30 revolutions and decided it would cause joint problems. The ball bearing in the handle was complete garbage.
I had a buddy of mine try it without telling him anything about it. First thing he said after doing a few reps was that it hurt his wrists. The good thing was Power Systems said I could return it.
So without a doubt, pass on the weighted jump rope.
