The machine’s lifting mechanism generates resistance without the need for additional weights or external resistance. This same motion provides support for the spine and stabilizes the abdominal muscles during each targeted exercise. The machine can be used one leg at a time for unilateral training. The auxotonic resistance system, with its progressive load, ensures optimal training across the entire range of motion, maintaining consistent effort in all favorable execution angles. The machine’s rotation and engagement of the abdominal muscles help reduce back strain and hyperlordosis caused by the action of the knee flexor muscles.

The assisted start feature helps users initiate the exercise by eliminating any residual or unsuitable load, making the movement smoother and more efficient.

Unlike traditional straight-backed seats, the VERTEBRAL DESIGN backrest segments provide superior comfort and support, adapting to individuals of various heights.
