THE LARGEST MUSCLE MASS IN ONE MACHINE - PUSHING THE LIMITS OF HUMAN PERFORMANCE
The A300 Leg Press was designed with a higher foot plate to increase hip flexion and decrease knee flexion. This maximises glute activation by causing them to work harder at the beginning of the movement. The decreased knee flexion reduces shearing forces, preserving the health of your knees. The separate foot plates allow you to train each leg independently, the way we function.
Features you won’t find in conventional machines. Unilateral movement means each limb can be trained symmetrically
✅ Large digital display that shows resistance, sets, repetitions, and peak power
✅ Thumb buttons let you change resistance without changing position — even during exercise
✅ Fast, easy, and precise eccentric overloading
✅ Change resistance in increments as small as one pound
✅ Industry-leading lifespan and uptime for years of use
✅ Unique versatility; five ways to train instead of only one
✅ Fully adjustable to accommodate a wide range of users
Why choose the A300 Leg Press?
Lower the risk of injury. Pain-free range of motion.
The A300 Leg Press reduces resistance where you're most vulnerable to injury. And the low inertia of Keiser's resistance system eliminates shock loading, sparing your joints and connective tissue from harmful forces.
Achieve your training goals faster.
Keiser's machines increase resistance, there 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. Kaiser'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.
Keriser's maintain their ideal resistance at any speed. That lets you train the strength, speed, power and endurance. And Keiser's digital control makes eccentric overload faster, easier, more precise. You get five ways to train instead of only one - giving you a unique advantage in achieving your goals.

- Change resistance during exercise without stopping.
- Convenient resistance controls are perfect for quick, precise, eccentric overloading.

POWER DISPLAY
Get instant feedback for testing and evaluation. The Power Display shows:
- Resistance level in (lbs. or kg)
- Sets
- Repetitions
- Peak power produced on each repetition
- Percentage of peak power
- Adjustment positions
Six-repetition Peak Power test calculates the resistance at which you achieve maximum power. Clear, one-inch numbers can be seen from a distance.

CHIP SYSTEM AND INTEGRATED TECHNOLOGY
Your electric workout card remembers and displays your previous workout:
- Resistance
- Sets
- Reps
- Adjustment Positions
Use Keiser Chip System with the Keiser Integrated Technology to download your workout on your phone, tablet, or computer.
