The New StairMaster TwistLock Dumbbells are the most space efficient and easy to use home dumbbell system available on the market today. The patented cutting-edge technology allows weight adjustments with the simple twist of the dumbbell handle. You never have to take your hands off the dumbbells - no knobs to turn, pins to align or levers to slide. You simply place each dumbbell into the cradle and twist the handle to your desired weight selection. Twist and Go! 

The TwistLock design looks like a dumbbell, feels like a dumbbell and delivers results like a commercial gym dumbbell set. Unlike many other adjustable style dumbbells on the market, the perfectly balanced TwistLock dumbbell delivers the same basic sizes as gym style dumbbells as you increase the weight. Whether you are using a 5 lbs or 50 lbs weight, the size of the dumbbell closely resembles the size of the same weight you would use in the gym. 

Paired with the custom stand (sold separately), the StairMaster TwistLock Dumbbells are convenient and attractive in the home setting and incorporate numerous thoughtful features with your performance and comfort in mind. The contoured and textured dumbbell handles provide a comfortable and secure grip during your workouts. For added safety, the TwistLock weight adjust system can only be made when the dumbbell is docked with the beautifully designed cradles that hold the dumbbells.
