The present invention relates to an exercise apparatus for exercising muscle groups in a person's legs by stretching and/or retraction, which exercise apparatus comprises at least a first frame and at least a first foot platform which foot platform is rotatable fastened to a hearing, which hearing is placed in relation to the person's foot for exercise at least plantar flexion and/or dorsal flexion, which exercise apparatus further includes a leg support. Hereby can be achieved exercising of the muscle groups by stretching and/or retraction (quadriceps lemons, biceps femoris, semitendinosus, semimembranosus, gastrocnememius, tibialis posterior, tibialis anterior, peroneus longus, peroneus brevis and soleus) in the legs of a person, and the muscles (soleus, gastrocnemius, tibialis posterior, peroneus brevis, peroneus longus, biceps femoris, semitendinosus, semimembranosus) at the back side of the legs.
