This Elite 90 set adjusts from 5 to 90 pounds in 5-pound increments, in effect doing the job of 28 pairs of traditional dumbbells. In essence, you'll be storing 2,565 pounds of free weights while taking up the space of just one dumbbell air (each 90-pound dumbbell is only 16 inches in length). And if that's not enough for your workouts, you can expand the set to 130 pounds per hand using the 8-11 Elite Big Block kit. Boasting black powder-coated weight plates in a traditional square shape, the free weights are ideal whether you're trying to build muscle mass, firm and tone your physique, or get rid of unwanted body fat. The Elite 90 dumbbells measure 16 by 6 by 6 inches (W x H x D) each and carry a 10-year limited warranty.
