The Hand Speed Trainers [$79.95] are a washable set of neoprene training sleeves designed for your forearms. Slots in the sleeves hold eight and four ounce weights that can be manipulated for an exact fit to resist your muscles while in action and build upper body strength and flexibility while you perform your daily routine or sport specific movement. Because of the snug fit from the neoprene design and the location between the wrist and elbow, you can turn any activity into functional strength building.
