The invention provides a hula hoop simulation body-building chair which is characterized by consisting a bracket, a support, a fixed plate, a rubber draw rod, a switch, a follow-up balance exercise loop, an electrodynamic balance exercise loop and balance balls, wherein the fixed plate is connected with the support; the support is connected with the bracket; the bracket is provided with the switch; the bracket is connected with the rubber draw rod; the rubber draw rod is connected with the follow-up balance exercise loop; the follow-up balance exercise loop is connected with the electrodynamic balance exercise loop. During exercises, as long as the follow-up balance exercise loop is held by hands and the switch is turned on, the balance balls in the electrodynamic balance exercise loop can move at a uniform speed, people can control the follow-up balance exercise loop to swing left and right as well as up and down according to the movement track of the balance balls in the electrodynamic balance exercise loop, so that the movement track of the follow-up balance exercise loop is the same as that of the balance ball in the electrodynamic balance exercise loop, as time passes, spirit pressures of people are unconsciously released, and the brains of human bodies are exercised to better control limb ability.
