Designed to improve the effectiveness of ab exercises and helps to engage and strengthen muscles in the back, chest, arms, and core. The carbon steel spring mechanism provides resistance while rolling out, increasing the activation of core and abdominal muscles.
Resistance Rolling Out - The mechanism offers a small amount of assistance when rolling back to the starting position, which allows users to extend farther while minimizing pressure on the lower back. Works On The Deep Core - Isolates and strengthens deep core muscles, including the important muscles that connect the pelvis and the spine. Improved core strength increases balance, improves posture and decreases low back discomfort caused by sitting.
