The NEW 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.

Patented TwistLock Design fast and easy weight adjustment with the simple twist of the handle to keep your workouts effective and moving.
Soft Grip Handle Design contoured handle that is textured to provide a comfortable and secure grip.
Durable Plate Design engineered to last with over molded high impact plastic body.
Dual Sided Weight Selection Windows highly visible weight selection windows located at each end of the handle for quick weight selection.
5 lbs Starting Weight w/ 5 lbs Increments weight increments accommodate users of all fitness levels.
Aluminum Weight Cradles are Included easy access and secure storage of the dumbbells. Plus with the open-end design of the cradles, they can be easily picked up and moved when needed.
Free Exercise Guide 20 distinct dumbbell exercises enabling a total-body workout for users of all fitness levels.
Parts Warranty 2 years (Residential Use Only)
