The SKLZ Core Wheels Ab Roller has a unique design, with two yellow wheels surrounding a foam handle. SKLZ claims that this design improves safety and ground control. These ab rollers are recommended by SKLZ to develop pillar strength (strength in the shoulders, torso, and hips) by enhancing traditional plank and push-up exercises. Both wheels are 9.5 inches long by 6 inches wide and 9.5 inches tall.
Reviews of the SKLZ Core Wheels are mostly positive. Users felt that these wheels had solid construction and rolled well. Some reviews also noted that the unique design helped target their abs more than their arms.
Buyers did wish the two wheels rolled independently to allow for users to make an arcing motion. A common complaint was that the wheel had poor durability. Some users also thought these rollers were not great for beginners and that using the rollers required an established level of core strength.
