Using Dumbbells for Punching

[FacePuncher]

In my experience it CAN help with technique and muscular endurance.

I don't see it doing much for your power because it's applying vertical resistance to your punches but you are trying to deliver force on a horizontal plane on most occasions.

Your deltoids will get beast though.

Ps. Only use small weights.. boxing is not a 10 rep sport.

Hi iron-man, I have seen guys do that at the gym with very light dumbells (3lbs)... I think it will build some strength overtime if you added it into your workout rountine... make sure you DON'T screw up your punching technique... I actual have been practicing punching under water at the pool...it's very different, but I'm just trying to shock my muscles a new way and trying to develope faster hand speed. I think there are training gloves that you can actually put small steel bars in the kuff area to load some weight on the gloves instead of using dumbells in your hands(ringside brand gloves I think) Cruiser

I'd recommend three pounds, as that's worked the best for me. It has kept my speed on par over the years.
