Ab Roller Wheel

A dual-wheel ab roller with a 7-inch-wide wheelbase that tracks straight instead of wobbling, so you can hold a rollout under control rather than fighting the tool. The wheels run on a sealed bearing over a knurled steel axle, and the contoured grips take a hard pull without twisting in your hands. A wide non-marking tread grips wood, tile and mat alike and will not skid out at full extension. One of the hardest and cheapest pieces of core training there is — from knees for most people, from the feet once you are strong. Comes with a foam kneeling pad. Rated to 300 pounds of user weight.
