A training apparatus contains a base, a sliding unit, a cranking unit, and a linking unit. The sliding unit contains two connecting strips with treadles at the back ends. A first flexible link and a second flexible link are arranged in parallel and connected to the two connecting strips. The cranking unit contains a wheel supported axially by an end of a crank arm which rotates synchronously with the wheel. The linking unit contains a third flexible link connected between the other end of the crank arm and the front end of one of the connecting strips. By the resilience provided by the third flexible link, the lateral and reciprocal motions of the sliding unit are prevented from getting stuck at the dead spots.
