The Everlast 2.5lb (1.13 kg) wrist and ankle weights are a great choice if you want to take your cardio workout to the next level. Not only will they help burn extra calories but they will also tone and strengthen numerous muscle groups including the biceps, triceps, thighs and quads. The double grip strip as well as contoured shape provide a secure fit and a thumb loop adds extra lifting support. The weights are one size fits most and come in a pair.
