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.

Strong lumbar extensors – for more stability in everyday life

Targeted back training

Your back muscles are active in almost every movement – whether walking, sitting, lifting, or carrying. If you want to relieve your spine and improve your everyday resilience in a targeted way, this is exactly where to begin.

The Lumbal Extension (LE) from Kieser was specially developed to strengthen the deep muscles in your lumbar spine in a focused and isolated way. With regular training, you actively build stability – for improved back function, an upright posture, and noticeably better back health.
