Keiser A400 Military Press Pro

The KEISER A400 Military Press Pro is engineered for high-performance shoulder training — delivering a significantly higher resistance ceiling than the standard model through a natural, slightly arched path of motion that replicates a free-weight overhead press while providing the joint safety, precision adjustment, and data intelligence of KEISER's pneumatic technology. The definitive overhead press machine for elite overhead athletes, strength coaches, and rehabilitation specialists.

• Advanced shoulder safety — virtually zero shock loading protects the sensitive rotator cuff and labrum from the jarring forces inherent in traditional weight-stack overhead pressing
• Optimised strength curve (DVR) — Dynamic Variable Resistance provides lower resistance at the start of the press, where you are mechanically weakest, increasing to full extension, where you are strongest — matching the human overhead strength curve precisely
• Independent unilateral arms — prevent  the stronger shoulder assisting the weaker, ensuring perfect bilateral symmetry development and enabling precise left-right imbalance correction
• Load-velocity profiling — critical for overhead athletes, including pitchers, quarterbacks, and throwers who must maintain high-velocity output throughout training sessions
• Performance drop-off alerts — set custom power thresholds; the machine alerts the user when output drops below the target percentage to ensure every rep is performed at maximum intent
• Quick-adjust seat and back pad — accommodates users of all heights in the correct posture and overhead reaching angle instantly
• Precision thumb-button adjustment — 1 lb / 1 kg increments for exact resistance management mid-set or between sets

Stocked at FSC Mayfair because overhead strength built on KEISER's pneumatic technology is safer, more precise, and more measurable than anything a barbell or weight stack can offer.
