Keiser A300/A400 Functional Trainer

The KEISER Functional Trainer is the industry standard in pneumatic cable machines — available in two configurations to suit different facility requirements. Because it uses air rather than iron, it has virtually zero inertia, allowing users to perform explosive, high-velocity movements without the shock loading to joints that occurs with traditional weight-stack cable machines.

Choose the A300 for the definitive pneumatic cable training experience, or the A400 for a data-driven environment requiring real-time velocity, power, and range of motion feedback on a 15.6" touchscreen.

• Zero-inertia pneumatic resistance — enables explosive, joint-safe movements at any velocity; impossible to replicate with weight stacks
• Full cable travel: 140" (3,556 mm) unilateral / 70" (1,778 mm) bilateral — accommodates the full range of cable exercises across all planes of movement
• Thumb-button resistance adjustment — A300: 1 lb / 1 kg increments | A400: 0.1 lb / 0.1 kg increments for elite precision
• A400 15.6" colour touchscreen — real-time tracking of velocity, range of motion, and power output for data-driven performance coaching
• Freestanding or floor-mounted — configurable to suit any facility layout

Stocked at FSC Mayfair because no other functional trainer delivers the precision, smoothness, and versatility of KEISER's pneumatic technology — and the A400 takes that further with data that changes how coaches train athletes.
