The invention discloses an idle, disc, magnetic drum and sine wave four-load type turntable body builder with analysis. The body of the turntable body builder is supported by two upright posts; and the body is provided with four body building turntables including an idle turntable, a disc load turntable, a magnetic drum load turntable and an imitation ship steering engine load turntable. In the invention, by combining multiple turntables, more selectivity and interestingness of body building exercises are realized; the sine wave tooth-surface differential load source and the differential magnetic attraction and exclusion load source of the magnetic disc and magnetic drum both have distinct characteristics and realize a body building and exercise effects hard to predict by the technicians of the field; and a data analyzer analyzes and displays the data of exercises to realize intelligent guidance of body building exercises. The body builder disclosed by the invention is simple in structure and strong in practicability, can meet the diversified body building and exercise requirements and has a broad market prospect.
