The invention relates to the field of fitness equipment, in particular to a sitting type
pectoral muscle pushing and lifting
strength training device. The sitting type
pectoral muscle pushing and lifting
strength training device comprises a supporting cross beam, the supporting cross beam is of a horizontally-extending structure, a
backup plate supporting plate is fixedly installed at one end of the supporting cross beam in the length direction, a reinforcing plate is fixedly installed at the other end of the supporting cross beam, and a bent part extending in the direction of the
backup plate supporting plate is integrally formed at the top of the reinforcing plate; and one end, far away from the reinforcing plate, of the bending part is fixedly connected with one side of the
backup plate supporting plate. According to the sitting type
pectoral muscle pushing and lifting
strength training device, multi-stage adjustment is achieved through the resistance adjusting
assembly, a
threaded rod can be driven to rotate through a driving gear and a driven gear by rotating an adjusting knob, a toothed plate horizontally moves and is meshed with the driving gear to rotate, and then the abutting strength of a positioning wheel and a pull
rope is adjusted; the tension degree of the tension
rope is changed to achieve resistance grading change, the resistance requirements of different
crowds such as novice and advancer can be met, and the application range is greatly widened.
