Keiser A400 Lower Back
The A400 Lower Back is built to strengthen and protect the lower back. Unlike weight-stack machines, its low-inertia pneumatic resistance reduces joint stress and removes shock loading, and with it the risk of injury. That makes it suitable for every fitness level, from older adults to elite athletes.
With the built-in A400 technology the machine tracks performance in real time and syncs with the Keiser Metrics App, so training can be guided by measured data.

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.
