Equilibrium training device


An equilibrium training device mainly comprises a chassis, a crank component, a pedal and a revolving inertia auxiliary roller set. When the user stands on the pedal for rotary equilibrium training, the belt and the first/second rollers of the revolving inertia auxiliary roller set are pulled together in tune with the rotation of the flywheel, so the swinging uncertainty of the pedal in revolution could be eliminated, such that the pedal could swing smoothly via the inertia of its swinging path, thus avoiding falls due to loss of equilibrium and improving greatly the security, convenience and practicability..
