Assume an upright sitting position, place your feet on the foot bars and grasp both handles with your hands. Push your body upwards without fully extending your legs. Slowly lower your body back down to the starting position. Make sure that the angle of the knee joint is always greater than 90°. Move your body up and down evenly.


Perform the exercise so that one leg alternately exerts more pressure on the foot bar than the other.


The training time can be increased to improve performance. Regulate the speed of movement (sometimes faster, sometimes slower).
