Vertical RocketGet ready to blast off with these rockets! Small hands? Big hands? Strong hands! These are great for training your vertical lifts, and translate well to sports that require a firm grasp of tubular handles, such as racquet sports, hockey, golf, baseball, etc. Get the smaller diameters for your day to day working sets and grab a couple of larger diameters when you're ready to challenge your open hand strength! Even hang them in pairs for doing pull ups.
