Butterfly, seated is necessary for the training of athletes of various sports, and is very effective in the formation of a strong and beautiful torso. Due to the difficulty of performing the “pushing hands together” exercise with dumbbells, the butterfly trainer is very popular among women and beginners, because it forms the correct execution technique, focusing exclusively on the chest muscles. Adjustable seatback angle allows you to load different areas of the pectoral muscles (upper, middle, and lower sections). The easy start device eliminates muscle injuries and facilitates training for people with an initial fitness level.
