FIELD: sports equipment. SUBSTANCE: apparatus has shaft gripped by hands and mounted in support for rotation about its axis of rotation and loading device kinematically connected with shaft. Shaft has cylindrical portions 6,8 of different diameter interconnected by conical portions 7,9 and barrel-shaped portions 10. Length of each portion is at least equal to width of hand grip. Loading device mounted on free end of support column 3 has sleeve 13 secured to column 3 in axial alignment with shaft. Sleeve 13 is joined with surface of projection 12. Sleeve 13 has radial through openings 14 for receiving screw 15 carrying C-shaped shoe 16 mounted within sleeve 13 so that its position may be altered and fixed. During training sportsman rotates shaft by sequentially gripping portions 6-10 from top or bottom in the direction away from sportsman or toward him to accomplish first program (6-6), second program (8-8), third program (7-7), fourth program (9-9) or fifth program (10-10). Each program provides selective action upon different groups of muscles by redistribution of loading due to altering extent of hand grip. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 dwg
