These color coded weighted balls are small enough and flexible enough to grasp with one hand yet big enough to hold with two hands. These hand-held weights are a great alternative to using traditional dumbbells as they have all of same benefits but are easier to hold. Available in 6 weights ranging from 1.1lbs to 6.6lbs (0.5 kg to 3 kg). Each ball measures 5” in diameter and can be inflated or deflated with a bicycle pump to make them easier or harder to hold.
