KIESER EXERCISE MACHINE

The Lumbal Extension – targeted relief for back pain

The LE machine is the centerpiece of the Kieser back training programme. It was specifically developed to strengthen the deep lumbar extensor muscles in the lower back – precisely where back pain most commonly occurs. By securing your pelvis and thighs, you ensure that only your lumbar extensors are working – in a controlled, safe, and effective way. This allows even acute or chronic lower back pain to be addressed in a targeted manner.

The Lumbal Extension is ideal for rehabilitation, prevention, and sustained strengthening of your back muscles – for greater stability, upright posture, and resilience in everyday life.

How to train your back

Effective back training depends on isolating the deep lumbar extensors – without support from gluteal muscles or the muscles at the back of your thighs. The computer-assisted Lumbal Extension (LE) machine enables exactly that.
