The invention relates to the field of exercise equipment and specifically to outdoor fitness equipment. An exercise machine is in the form of a stationary rigid metal construction which is unable to be disassembled and which includes a support frame (1) having an axle (2). The axle (2) is in the form of two coaxial half-axles provided on the outer side of levers (3). The latter are pivotally mounted on the uprights of the support frame (1). Limiters (4, 5) for limiting the movement of a weight (6) are in the form of transverse connections between the levers (3) and are installed on both sides of the axle (2). A load guide (7) is provided between the limiters (4, 5) and is in the form of a bent rod having two rectilinear portions and an arc. The load guide (7) is installed in such a way that the axle (2) of the support frame (1) passes through the common center of gravity of the entire set of weights (6) located to the left side of the arc. The tilt angles of the rectilinear portions of the guide (7) are at an angle which exceeds the level of the horizon line by no less than 2-3 degrees irrespective of the position of the levers (3). The weights (6) are positioned on the guide (7) with the necessary percentage ratio on both sides of the axle (2). A limiter (8) of lever (3) position is in the form of a U-shaped frame and is affixed to the levers (3). A bench (9) is mounted on the support frame (1). An exercising individual is thus safer and it is possible to regulate loads on levers with grips. |
