ROW YOUR WAY

Specifically designed to isolate the upper back, the A400 Biaxial Upper Back differs from anything else. It guides you through a range of motion that optimizes the effect on all of the muscles of the upper back. It’s unilateral movement promotes symmetry by preventing the strong side from helping the weaker side. Unlike conventional machines that use iron, the A400 Biaxial Upper Back’s low‑inertia design gives you a smooth resistance. And it’s perfect for people at any fitness level.
