Keiser Performance Exercise Machines - Pneumatic Resistance Machines (For Performance & Rehab)

Keiser Strength Training Machines use Dynamic Variable Resistance which safely builds strength at any speed; which is the key to building maximum power (Force x Velocity). Keiser strength machines enable you to develop power, and Power is the key to Performance.

With Keiser Pneumatic Technology, the muscles remain active and engaged throughout the entire range of motion and velocities, with reduced shock loading to muscles, connective tissues and joints, which allows for workout regimens that can safely improve physical performance in ways not seen with traditional strength-training methods.\


How It Works
Keiser Strength's singular, foundational focus on improving human performance has resulted in the development of products designed to revolutionize fitness and wellness. Iron and weight stacks have shown results, but they have reached their limits. Keiser represents a fundamental change in approach for challenging and exceeding the status quo.

  • Power - Power = Force (strength) x Velocity (speed). Training can only be considered functional if it is done at speed. Keiser has created the technology that allows users to train at speed, on every machine, for every movement.
  • CNS/NMS Training - Keiser helps retrain the user’s central nervous system and neuromuscular system, allowing for slow training/slow performance or fast training/fast performance.
  • Versatile - Keiser’s equipment solutions and programs are developed with the full spectrum of users in mind, from the performance athlete to the older adult.
  • Safer - Keiser maximizes muscular and neuromuscular output while minimizing stress on the joints and connective tissue, resulting in a reduced risk of injury.
  • Solutions - Keiser equipment provides solutions for a range of different markets including: sports performance training; medical rehabilitation; low impact training for older adults; armed forces & emergency service training.
