SteelBells are a top Dude Gift for an Athlete and Gift for a Man pick. The diameter of a 10-pound SteelBell is 9", while a SandBell of the same size weighs just 4 pounds. Rogue Fitness describes the difference between SteelBells and traditional free weights as "the difference between picking up a sleeping child and one that is flailing." A 20-pound SteelBell will feel and respond like a much heavier weight compared to SandBells or regular free weights. The steel shot-filled SteelBells are available in weights ranging from 5 pounds to 125 pounds, with Amazon stocking a range of 10 to 40 pounds. These smaller, more dynamic versions of free weights by SteelBell creator Hyperwear add training intensity, build core strength through constant stabilization, and reduce injuries and floor damage during workouts. The extra-thick neoprene casing of SteelBells holds a horde of steel shots that move faster than sand, increasing instability and requiring users to grip harder, focus on balance and coordination, and engage core muscles. In comparison to SandBells, SteelBells' shots move more like water than sand, making them a unique and challenging workout tool.
