StairMaster TwistLock Adjustable Dumbbells

To replace 550 pounds of traditional gym dumbbells, home exercisers need only pick up two: StairMaster's TwistLock set. The adjustable dumbbells start at 5 pounds and climb by 5-pound intervals to 50 pounds, up to 100 pounds combined, so beginners, intermediate, and veteran circus strongmen alike can use them to get a solid workout. The dummbells adjust quickly and without removing their hands from the handles: users place them in cradles, twist to the new weight level, lock, and go. This user-friendly design appears in many details: the ergonomic, soft-grip handles, the durable plates, and even the fact that the dumbbells resemble traditional weights, so using them feels natural.

About StairMaster

Since 1983, designers at StairMaster have proudly built fitness machines that users "love to hate." Their demanding products deliver results: improved physical fitness and a healthier body. Their original machines stimulated stepping up, toning the lower body particularly well. On more modern models, a stairway actually unfurls as users move, mimicking the act of climbing stairs or dwelling in a middle tier of purgatory even more precisely. Though the brand remains dedicated to their original design, they've expanded their fitness line to include other fitness gear.
