A resilient wood floor for aerobic exercise. The boards of the floor are free to pivot in tongue and groove joints. The wood is laid on a foam pad which will always yield during ordinary human exercises. The boards are held together by spring clips which lengthen when a load is applied to the boards, while holding the boards close together in a manner to prevent pinching.
