BMM 21/A - MasterSport.% Multi-functional strength trainer for 4 people at a time, consisting of two rope stations and a lower and upper lift. The design of the lower lift has been modified to increase the stability of the workout. The trainer is designed to exercise the double- and triceps muscles of the arms, the broad back, the back muscles, the chest muscles and the shoulder girdle. The tower is constructed of 125x60x3 flat oval profile. The uprights are equipped with a magnetic load selector. The upholstery elements are adapted to the anatomical shape of the exerciser, which promotes comfort and safety of use. The elements in direct contact with the feet are made of chromonickel sheet with special non-slip rubberised slats to ensure greater stability and safety during exercise. The 7-step roller pressure adjustment allows the machine to be adapted to the height of the person exercising. Thigh adduction and thigh inversion positions with leg holder are included as standard. For greater stability during movements, a double bar attachment for overhead pull-up and a double bar attachment for downward pull-up are provided. In addition, there are two separate independent hand pull handles on the overhead for overhead lifting.
