Exerciser Develops All Muscles (Jun, 1932)

Exerciser Develops All Muscles
EVERY muscle in the body is brought into action when you start swinging on the exerciser shown below, which can be operated by one or two persons.

The “gyro wheel”, as the device is called, is designed to revolve in all directions and is made entirely of metal. The direction and movements of the wheel are controlled by the movements of the body.
