GREAT AB AND UPPER BODY TONING – Strengthens abdominals, shoulders, arms & back all at once, so you get an efficient toning workout. As your abs work to keep you balanced, your arms and back muscles engage as they work to keep you stable and controlled
BETTER STABILITY – Dual wheels allow for greater stability than models with just one wheel, so you can focus more on safely strengthening your abs and less on trying to control the movement with your arms
EASY GRIP – Two easy-to-grip handles are designed with slots for your fingers for improved comfortability that won’t easily slip as you roll back and forth
