Get the most out of your new StairMaster TwistLock Adjustable Dumbbells with the new TwistLock Dumbbell Stand. The heavy duty steel frame allows you to mount your TwistLock Dumbbell cradles to the stand at the optimal height for quick and easy access to your TwistLock dumbbells.The design of the stand was carefully considered in order to allow the user to get between the dumbbells so that proper lifting form could be followed. This means less strain on your back since you can lift the dumbbells out of the rack with your legs instead of your back.
