Although this listing is for 1 (one) 17 pound dumbbell, the Life Fitness dumbbells are available up to 20LB in weight. Exercisers can intuitively pick the dumbbell that matches their fitness level and goals. The anti-roll head was designed to be set down without rolling away, but rounded enough to be pushed aside to make space. The high-quality urethane protects both your dumbbells and floors from any nicks, scuffs or streaks. The construction of each dumbbell features a 5 inch long contoured ergonomic handle with an embossed gripping pattern and 1.25 ince diameter for comfort.
