A motorized gymnastic training apparatus has first and second planar support members and a central support member attached through the first planar support member into the second planar support member. The central support member has a wheel rotatably mounted on one end thereof. The central support member may have a central sleeve attached through the first support member with a sliding or telescoping member passing therethrough so that the wheel and the second planar support member can be adjusted relative to the first planar support member with a pin locking the sleeve to the telescoping central support member. An electric motor is positioned within the central support member and is coupled to the wheel through a belt and a pair of pulleys attached to the wheel shaft and to the electric motor shaft for rotating the wheel in a forward or backwards rotation responsive to the actuation of a switch. The switch can be mounted on the second planar support member so that a person using the gymnastic training apparatus can actuate the switch to an on/off position or to a forward or reverse direction. A plurality of removable secondary wheels can be attached to the first planar support member for use in training an individual to use the gymnastic training device after which time the secondary wheels can be removed.
