Steel. Chrome. And a touch of foam. This is recipe chosen to create the perfect adjustable dumbbells! Our Ultra Compact Synergee Dumbbells are sold in pairs and are available in 3 different weight options; and each individual dumbbell is equipped with 4 levels of weight adjustments. Choose between 10 lbs, 15 lbs, and 20 lb options. The 10 lb dumbbells can each be adjusted to 5 lbs, 7 lbs, 8 lbs, or 10 lbs. The 15 lb dumbbells can each be adjusted to 7 lbs, 10 lbs, 12 lbs, and 15 lbs. And the 20 lb dumbbells can each be adjusted to 10 lbs, 14 lbs, 16 lbs, and 20 lbs. The design of these dumbbells is genius: weight adjustments are made with a simple spin of chrome-coated steel plates. Each plate locks into place so there is no need for collars! The handles are coated in foam to provide a comfortable grip. Underneath that foam is strong steel that will last rep after rep. The weight plates’ chrome finish increases longevity and durability. From strength training to Pilates to barre, these dumbbells can be adjusted for all your workout needs!
