This type of weightlifting machine is used to train the leg muscles, namely the quadriceps and biceps, located on the front and back of the thigh respectively. Transition of the structure from the position for "lying flexion" to the mode for "sitting flexion" and vice versa is realised by means of a spring lock.
As a result, the seat and backrest are realigned, changing their original position. The adjustment of the swivelling roller is realised along the entire length of the lower leg.
This versatility allows you not to buy two separate trainers, but to perform both exercises on one with greater comfort and efficiency. The machine is equipped with rubberised steel plates with Teflon bushings, which guarantees smooth gliding and quiet operation.
For better development of the thigh muscles, it is recommended to also exercise with a professional barbell.
