Sports training device for creating adjustable load (variants)

An exercise machine to generate adjustable loads, the exercise machine comprising:

• a rack;
• a swinging axis fixed on the rack;
• elements for applying a trainee's force;
• and
• a loading device to generate an adjustable load, the loading device comprising load weights and a U-shaped guide performing a function of protection against unauthorized theft of load weights, one end of the said loading device being connected with a bracket to the swinging axis, a swinging plane of the said loading device being oriented parallel to a bearing surface, a centre of gravity of the loading device being either shifted to the left or right of the swinging axis or coinciding with the swinging axis under a minimum load, and the said elements for applying the trainee's force being installed, relative to the said loading device, at a preset height (A) from the bearing surface, in accordance with a direction of the trainee's force and with a set of muscles to be loaded, wherein a lever comprises a portion that extends between, and that is attached to, a first end and a second end of the U-shaped guide, the U-shaped guide comprising straight portions connected by angled portions.
