PRESS INTO A NEW STANDARD
The A400 Seated Calf was engineered to develop explosive lower-leg power, originally designed for world record holders Willie Banks (triple jump) and Mike Powell (long jump). Featuring unilateral movement, it ensures balanced strength development by allowing each leg to work independently. The machine automatically pre-loads and adjusts for leg length, providing a customized fit for optimal performance. Unlike conventional weight-stack machines, the A400’s low-inertia, pneumatic resistance delivers smooth, controlled movement, reducing stress on joints and minimizing shock loading. Integrated with Keiser’s advanced A400 technology, it tracks real-time performance metrics and syncs seamlessly with the Keiser Metrics App for data-driven training optimization. The A400 Seated Calf offers a safer, more effective way to build lower-leg strength and power.
- Offers unilateral movement, each limb can be trained symmetrically
- Increased resistance range for more intense functional workouts
- Smooth Keiser Dynamic Variable Resistance, fully adjustable to accommodate a wide range of users
- Large digital displays with resistance and counted repetitions
- Resistance range : 0 – 369 kg
A400
- Intent: Research indicates real-time visual feedback can increase athlete intent. A400 technology provides the feedback that inspires improved performance.
- Velocity: In addition to Power, work now with Velocity based methodology
- Range of Motion: Identify imbalances between left and right limbs that can lead to underperformance and injury (on unilateral machines only). Train or rehab for symmetry.
- Load Velocity Profile
- Data: Quantify progress in load, velocity, and power automatically. Then, bring it into your analytics or records system so you can track everything.
