Meet the YBell Arc weight: a 4-in-1 fitness tool that works as a dumbbell, kettlebell, medicine ball, and push-up stand. It is neoprene coated for a comfortable workout. You will simply have to change your grip to switch mode.
By grabbing the YBell by the center grip, you can use these as dumbbells. Switch to outer or top grip for kettlebell training or push ups.
