Query: 4 lbs of burn!

I upgraded to these when my 1 lb ea. gloves died (or refused to be washed anymore). The design of the glove is the same as my old ones, with the weight on top of your hands; they are heavy and become a little loose after about an hour...but I can't think of a better design that allows your fingers and palms to be free (so you can keep them on when doing pushups). I use them for Turbo Kickboxing and Shadow Boxing classes and love 'em. Biggest difference between the 1 lb and 2 lbs - light arms @ workout end! You feel like you can fly away. After using these for another month, maybe I will.
