KIESER EXERCISE MACHINE

Infimetric Leg Press

The i-B6 leg press is a proprietary infimetric exercise machine – no weight stack, but maximum effect. Instead of moving weight, your legs work actively against each other: one leg pushes, the other resists – controlled and precise. This generates an intense stimulus on your leg muscles – for targeted muscle growth, more stability, and highly effective training.

Why is that important? Your leg muscles are the largest muscle group in your body. They ensure your mobility, posture, and force transmission. Regular training strengthens your performance – and protects you from falls, pain, and age-related strength loss. Intensive leg training also activates your metabolism – with positive effects for your cardiovascular system.

A New Kind of Intensity

With the i-B6, you generate resistance yourself – by actively pushing with one leg and simultaneously resisting with the other. This allows for finely adjustable load – even with existing conditions – and consistently intense training throughout the entire range of motion. With the introduction of the infimetric training principle in 2018, Kieser established a new form of muscle strengthening: no weight stack, no rest for the muscle – but maximum control and stimulus. Ideal for anyone who wants to build their leg muscles in a targeted way and noticeably increase training intensity.

A new kind of intensity

Greater range of motion – more mobility, more performance

Rotation mechanism – targeted relief for the knee joint

Sensorimotor feedback – brain meets muscle

A key feature of the i-B6 leg press is the integrated rotation mechanism of the footplates. In the last ten degrees of knee extension, the shinbone automatically rotates outward by five degrees – biomechanically effective and purposefully integrated to ensure proper loading of your knee joint. This rotation supports an even distribution of force in the joint and can reduce harmful stress on your ligaments.

The result: safe, controlled leg training without weights, with full effect on your thigh muscles and minimal stress on your knee structures.

Weight alone doesn’t determine whether your training is effective – your perceived exertion does. For real muscular adaptation to occur, it’s essential that you keep going until another repetition is no longer possible. The i-B6 supports you optimally: thanks to finely adjustable resistance, ball-bearing joints, and custom settings, you train your leg muscles effectively, precisely, and efficiently.

Train your leg muscles with the i-B6

Effective leg muscle training requires controlled extension and flexion of the knee and hip joints – without compensatory movements or activating supporting muscles. This ensures that your leg muscle training is not only targeted and effective, but also comfortable and accessible.
