Keiser A400 Arm Curl

Keiser A400 Arm Curl

Safe and effective biceps development: the unilateral movement promotes symmetry because the stronger arm cannot help the weaker one, while smooth pneumatic resistance allows precise control and a safer movement pattern.

The elbow is easy to align with the pivot of the exercise arm, and the grips adjust automatically to forearm length. The A400 technology tracks performance in real time and syncs with the Keiser Metrics App.

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.
