TINY BUT POWERFUL
Using the A400 rack for Velocity-Based Training unlocks the full potential of foundational lifts like the squat and bench press. These multi-joint movements are ideal for measuring force and speed because even small changes in bar velocity directly reflect an athlete’s power output and neuromuscular readiness.
The A400’s pneumatic resistance provides smooth, consistent load through the entire range of motion, unlike traditional weights that lose tension at certain points. This lets athletes safely accelerate every rep, making it perfect for building explosive power and refining technique.
Real-time velocity feedback on the rack turns each lift into data-driven insight: track fatigue, optimize intent, and ensure every rep is performed at the right speed for the desired adaptation.
- Ability to combine Keiser Dynamic Variable Resistance and iron weight resistance
- Keiser Dynamic Variable Resistance pulls straight down on the bar (just like gravity) and follows the bar as the bar moves horizontally
- Train at any speed, from controlled to explosive, developing Power and Stability
- Ability to do heavy negatives at the touch of a button or foot operated pedal
- All-in-one system to accomplish more in less space
- Optional custom paint, platform, and logo at additional cost
