How it works – assisted ab wheel motion

The built-in spring mechanism stores energy on the rollout and assists your return. This helps you maintain proper form, extend your sets and strengthen the core faster.

Stability & safety

Four wheels with non-slip rubberized surfaces and a wider stance keep a stable path even on smooth floors. The construction distributes load evenly, so your abs work more while your arms compensate less.

User comfort

Wide, contoured elbow supports and the included soft knee mat let you train longer without discomfort. The phone holder keeps your smartphone secure — follow your plan or a video coach.
