Pneumatic air resistance
Smooth resistance that can be adjusted quickly without heavy stacks or plates.
The Keiser Difference
Keiser is not just gym equipment. It is a strength, power and healthspan technology system.
Pneumatic resistance helps facilities train strength and speed with smooth, measurable loading for older adults, athletes, clinics, schools and premium wellness environments.
Low inertiaLess shock loading than traditional mass
MeasurablePower, velocity and range feedback
Broad useHealthy ageing through elite performance
Technology made usable
Simple points decision-makers can understand quickly.
Low-impact loading
Reduced shock loading to muscles, connective tissue and joints compared with traditional mass-based resistance.
Strength and speed
Train controlled strength, faster movement and power without the inertia of iron.
Dynamic Variable Resistance
Resistance that supports movement intent across a wide range of users and speeds.
Safe for older adults
Approachable loading for longevity, balance, confidence and strength-for-life programmes.
Powerful for athletes
Fast, precise loading and feedback for performance environments.
A400 data and feedback
Real-time power, velocity and range-of-motion insight for training and rehabilitation conversations.
Education-led adoption
Demonstrations and handover support help teams use the technology properly.
A400 technology
Data that makes strength and power easier to discuss.
A400 technology provides real-time visual feedback and performance insight, including power, velocity and range-of-motion data. That helps coaches, clinicians and operators turn each session into a clearer conversation about progress.
