Abstract:
An exercise step with air-cushioning legs. The exercise step (1) includes a plate-shaped panel (10), and air-cushioning legs (30). Each of the air-cushioning legs is provided under the panel to support the panel, and absorbs a load applied to the panel by air cushioning effect. The exercise step has a high air cushioning effect, thus protecting a user's knees from injury, allowing the user to exercise in comfort and safety, and minimizing noise generated during a cushioning operation. Further, the exercise step prevents the panel from being deformed due to a load applied to the panel.
