EXPLOSIVE, BALANCED POWER
The A300 Seated Calf was originally designed for world record holders Willie Banks (triple jump) and Mike Powell (long jump). It features unilateral movement to help develop balanced explosive lower leg power. The machine automatically pre‑loads and adjusts for leg length. Unlike conventional machines that use iron, the A300 Seated Calf’s low‑inertia design gives you a smooth resistance. The result is a workout unlike anything else on the market.

Why choose the A300 Seated Calf?
Lower risk of injury. Pain-free range of motion.
The A300 Seated Calf uses more resistance where you’re stronger and less where most vulnerable to injury. And the low inertia of our resistance eliminates dangerous shock loading on muscles, connective tissues, and joints. This significantly lowers the risk of injury and pain during exercise.
Achieve your training goals faster
Our machines increase resistance where you’re stronger and decrease resistance where you’re weaker. This allows your muscles to work at their full potential through every point in the range of motion.
Keiser’s machines focus on efficiency. The goal is to maximise your workout with fewer reps, so you spend less time working out and more time living.
Train at any speed — unlike conventional equipment
Training with conventional equipment is often most effective at slow speeds. Your brain remembers the speed patterns of those slow movements. To be fast, you must train faster. Keiser’s low‑inertia resistance is effective at any speed.
Unmatched versatility to achieve any goal.
Our machines maintain their ideal resistance at any speed. That lets you train for strength, speed, power, and endurance. And Keiser’s digital controls make eccentric overloading faster, easier, and more precise. You get five ways to train instead of only one — giving you a unique advantage in achieving your goals.
