The Keiser Advantage
Keiser PRT
Conventional Iron
Strength
Power
Speed
Do more, more effectively.
Keiser's Pure Resistance Technology™ (PRT) is more effective than iron across a wider range of training themes.
More effective at faster tempos to improve velocity and power.
Just as effective at slower tempos
to improve strength.
Thumb-Button Resistance Control
Eccentric and Isometric overload made easy.
Change resistance at any point during a rep with push-button convenience and digital precision. Get into a starting position, then increase resistance for eccentric or isometric training.
A400 TECHNOLOGY
Next-Gen technology. groundbreaking Performance Insights.
A400 technology offers visual feedback and performance insights in real time.
And you can export A400 data for use in your analytics or records platform, whether it’s custom or off-the-shelf.
Power
See mean and peak power for each rep.
Velocity
See mean and peak velocity for each rep.
Range of Motion
See data for both concentric and eccentric phases for each rep.
Unilateral Comparison
See velocity and power data for left and right side by side on unilateral machines.
Custom Performance Drop-off
Know when reps become less effective. Optimize training time and reduce risk of injury.

Every workout can be a test.
Get testing data from every workout. Make program changes in real time to optimize workout time and continue to progress.
Quantify progress automatically.
Capture vast amounts of performance data in the weight room or clinic. A400 makes it easy to capture force, velocity, power, and range of motion to track progress.
Maximize performance with real-time, visual feedback.
Research indicates real-time visual feedback can increase athlete intent. A400 technology provides the feedback that inspires improved performance. .
Performance drop-offs show when to stop.
Set custom performance drop-off levels (e.g. 80% of peak power). See when more reps would produce diminished returns. Know when to end a set to save time and reduce risk.
