The invention discloses a leisure body-building chair, which relates to a chair specially suitable for special purposes. The leisure body-building chair comprises five parts: a chair body, a lower limb body-building mechanism, an upper limb body-building mechanism, a back massaging mechanism and an energy storage device, wherein the lower limb body-building mechanism comprises a pedal folding mechanism, a first-level folding mechanism, a second-level folding mechanism, a synchronous pulley mechanism a, a synchronous pulley mechanism b and a synchronous pulley mechanism c; the upper limb body-building mechanism comprises two handles, two power rods, two steel wire ropes, two pulleys, two stop blocks and two springs; the back massaging mechanism comprises an electromotor, a crank rocker mechanism, a shaft a, a synchronous pulley mechanism d, a shaft b, a synchronous pulley mechanism e, a shaft c, a hammering tool a and a hammering tool b; and the energy storage device comprises an engine and a storage cell. According to the leisure body-building chair, functions of training the upper limbs and the lower limbs and massaging the back on the human body are combined, and meanwhile, energy generated by motion is stored in an electric energy form so as to achieve a purpose of saving energy.
