Vary the position of your feet to target different muscle groups individually:
a) Feet at the upper edge of the footrest (optimal positioning of the feet in case of
knee problems): The muscle work is mainly taken over by the gluteal muscles (M.
glutaeus maximus) as well as the muscles on the rear of the thighs M. biceps
femoris, M. semitendinosus, M. semimembranosus)
b) Feet on the lower edge of the footrest: The muscle work is mainly taken over by
the front muscles on the thighs (M. quadriceps femoris).
c) Feet largely apart: The muscle work is mainly taken over by the lateral inside
muscles of the thighs (Mm. adductores).
d) Feet closely together: The muscle work is mainly taken over by the lateral front
muscles of the thighs (M. quadriceps femoris).

Adopt the right exercise position: Sit on the seat so that your upper body touches
the backrest completely. Make sure to adjust the backrest’s slope ergonomically to
counteract existing back pain.
For recumbent workouts position the seat as far
forward as possible and the shoulder rests as far down as possible in order to best
use the swing. Place your feet o
n the footrests about shoulder width apart. The
height of your feet on the footrest is determined by your legs, which should be bent
at an angle of approx. 90°. If you have knee problems, this angle should not be less
than 90°.
