The gymnastics apparatus, particularly for exercising the extensor muscles of the inferior limbs, thigh muscles and gluteus muscles, comprises a support frame for a gradually-yielding resistant element suitable for contact with a pelvic-abdominal region of the torso of a user moving from an initial position, in which the lower limbs of the user are bent, to a final orthostatic position, the resistant action of the resistant element being directed along a direction transversal to the longitudinal axis of the thigh bones of the user in movement.
