I have 1 lb. and 1.5 lb. weighted gloves. Honestly, sometimes I find using 1 lb. to 2 lb. handweights easier to use than the gloves. I love that they are easy to put down and pick up again, depending upon the combos. during fast moving punches, I sometimes prefer to put them down. With weighted gloves it takes a little more time to take them off, and I don't always put them back on, whereas with dumbbells, it's so easy to just grab them again. Don't underestimate the power of those little 1 lb. weights. Believe me you will feel them. As far as using 3 lbs. weights. I would only use them on a slower KB workout, where you have more control over your punches. Anything fast, you're better off going lower weight.
