These neoprene dumbbells are comfortable to grip. A smoothly coated neoprene coating prevents your hands from slipping, no matter how many reps youβre doing or how much youβre sweating. This will make your hands not get so tired and improved control over you exercise. Just like vinyl dumbbells, theyβre color-coded, so you can tell how much weight they are at a glance and such wonβt destroy your floors. Perfect for those cardio, toning, rehab sessions as well as anyone training with lower weight but for longer.
