Keiser A400 Biaxial Upper Back
The A400 Biaxial Upper Back is designed specifically to isolate the upper back. It guides you through a range of motion that best reaches every muscle of the upper back, while the unilateral movement promotes symmetry because the stronger side cannot help the weaker one.
The low-inertia design delivers smooth resistance instead of the shocks of iron weights and suits users at any fitness level.
Key benefits
- Unique axis of rotation allows greater range of motion in natural planes of movement
- Smooth Keiser Dynamic Variable Resistance
- Fully adjustable to accommodate a wide range of users
- Durable construction engineered for years of use
- Large digital display with resistance and counted repetitions
Keiser Dynamic Variable Resistance
Keiser's Dynamic Variable Resistance is designed to provide a smooth, consistent force curve at any training speed. Each machine has its own resistance curve, tuned for the muscles used in that particular exercise. For the user it means training at maximum efficiency at whatever speed they work.
