TD-0280-D. Combined exercise machine for lower back and thigh biceps.

This equipment Profijim is used to work the biceps of the thighs and lower back muscles. The trainer has a combined design, which allows it to be used in specialised and ordinary halls.To train the muscles of the lower back, the leg lifts are performed lying on the stomach. When performing the exercise, the axis of rotation of the working part of the simulator should coincide with the athlete's hip joint. The roller should be at the level of the shin. The movement is due to the effort of the back extensor muscles until the body is completely straightened. To train the bicipital muscles of the thighs, the legs are flexed in a supine position. However, the rotary axis of the working part of the simulator in this case should coincide with the knee. The roller should be placed at the level of the heel. The movement is due to the effort of the hip flexor muscles to absolute bending of the legs in the knees and contraction of the biceps femoris.
