Keiser Air250 Lower Back – targeted training for the lower back (MDR certified)

The Air250 Lower Back is a specially designed training machine for strengthening the erector spinae (lower back muscles). The machine complements core training concepts and enables controlled, guided back training with minimal setup effort.

The machine uses the Keiser Dynamic Variable Resistance system, providing a smooth and adaptive resistance curve. This allows efficient training throughout the full range of motion – independent of speed.

A key advantage is the MDR certification in accordance with the EU Medical Device Regulation. It confirms that the device meets strict requirements for safety, quality, and risk management, making it particularly suitable for use in professional training and rehabilitation Environments. Furthermore, the device has KGG approval (device-based physiotherapy), which means it is officially recognized for therapeutic use within equipment-based rehabilitation and can be specifically used in physiotherapy Treatments.
