Keiser A400 Leg Press

Keiser A400 Leg Press

The A400 Leg Press targets lower-body strength with smooth pneumatic resistance. The higher foot plate increases hip flexion and decreases knee flexion, which maximises glute activation at the start of the movement while reducing shearing forces and so protecting the knees.

Separate foot plates allow each leg to be trained independently, mimicking natural movement patterns and building balanced strength. The machine tracks performance in real time with Keiser's technology.

Key benefits

• Unilateral movement - each limb can be trained symmetrically
• Resistance range for intense functional workouts
• Smooth Keiser Dynamic Variable Resistance
• Fully adjustable to accommodate a wide range of users
• Bilateral movement for body symmetry training
• Large digital display with resistance and counted repetitions

Keiser Dynamic Variable Resistance

Keiser's Dynamic Variable Resistance is designed to provide a smooth, consistent force curve at any training speed. Each machine has its own resistance curve, tuned for the muscles used in that particular exercise. For the user it means training at maximum efficiency at whatever speed they work.
