Keiser A400 Lat Pulldown

The KEISER A400 Lat Pulldown is the high-performance, data-integrated evolution of the traditional back machine — using pneumatic resistance to enable high-velocity pulling movements that are impossible with a standard weight stack. No cable slack, no jarring at the start of the movement, no momentum helping you at the bottom — just pure, consistent muscular engagement through the entire range of motion.

• Independent exercise arms — unlike traditional single-bar lat pulldowns, each arm moves independently to prevent the stronger side compensating for the weaker, and allows a more natural converging path of motion
• Dynamic Variable Resistance — resistance increases as you pull lower, precisely matching the natural strength curve of the human body for a more efficient and effective stimulus
• Zero-inertia training — no weight stack means no momentum assisting the bottom of the rep, forcing continuous muscle engagement throughout the full range of motion for superior fibre recruitment
• Adjustable quick-release thigh rollers — accommodates users of all heights, keeping the user securely locked in during heavy or explosive pulls
• Mid-set resistance adjustment — thumb-button controls on the handles allow instant resistance changes without breaking form or interrupting the set
• A400 velocity and power drop-off monitoring — particularly valuable for swimmers, overhead athletes, and climbers who need to maintain explosive pulling power throughout a set

Stocked at FSC Mayfair because the A400 Lat Pulldown delivers a back training stimulus that no weight-stack machine can replicate — and the athletes who use it feel the difference immediately.
