Using Dumbbells for Punching

[marbleheadmaui]

Thanks for your replies... all been helpful with your views for it.

I wasn't going to use heavy weights, maybe 3-4 kg... helping with my endurance and keeping the weights up like a guard effect to get use to control weight for perhaps 4 rounds of light jabbing and left/right hooks combos or mix it up etc... just a boost to strengthen my upper body keeping the weights by my face as a guard etc and as an endurance benefit, wont be rapidly punching with weights as it will cause injury... call it a benefit boost to generate a strong guard, and crisp up the combos etc thanks for the help much appreciated

That's WAY too heavy. Punching is about speed. You want some endurance work? That's fine. But you shouldn't be using dumbells over 1 pound, not a kilo, a pound.
