legs reach an angle of approx. 90°. Breathe in during the return sequence.
Exercise variations:
⊗ You can also perform this exercise with only one leg. This prevents the stronger
leg from performing more of the work.
⊗ 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)
