SUPERIOR UPPER BACK ISOLATION
Specifically designed to isolate the upper back, the A350 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 A350 Biaxial Upper Back’s low‑inertia design gives you a smooth resistance. And it’s perfect for people at any fitness level.
Avoid repeated shock loading: The A300 Biaxial Upper Back has virtually none of the sudden excess forces you get from iron.
Protect your joints: With almost no shock loading, you avoid much of the risk to joints and connective tissue over time.
Less pain when you work out: Without the shock loading of iron, you get all of the benefits of strength training with significantly less pain.
