I definitely agree with Catherine. I do use weighted gloves, or 1 lb dumbbells when I'm doing a workout that isn't too fast, but I took the advise of my cardio kickboxing instructors. They are Tae Kwon Do instructors, and the cardio kickboxing they teach us is super fast. They don't recommend the use of weighted gloves. Now I know why. Now I only use them when I'm doing a slower paced kickboxing workout. I would use them with something like Rumble, but I don't think I'd use them with Kick, Punch & Crunch. Also, I find 1 lb. is really my max. The ones that came with my turbo jam workouts tend to get too heavy for me to workout safely.
Enjoy your new gloves. I myself am looking for a comfortable handwrap. I love the ones Cathe and crew used in Kickmax.
