A rectangular board has support surface with two spaced apart parallel arcuate rockers. Each rocker has a flat portion adjacent to one edge of the rocker board. The flat portion makes an angle of approximately 45 DEG with the upper surface of the board. A hemispherical pedestal or projection is formed between the two rockers on the underside of the board. The board has structure to assist in the performance of multiple exercises. A person standing on the board may hold the upper portion of the body in a substantially vertical position, with the lower extremities of the body then following the board back and forth as it rocks. In a second exercise, the board is held so the flat portion of the rocker holds the upper surface of the board at an angle of approximately 45 DEG to the ground. The user's toes are placed on the ground with the heels extended up the 45 degree ramp until the ankle joints are stretched. Similarly, the heels of the feet may be placed on the ground with the toes placed in the upward position. When the board is turned upside down the rockers extend into the air and the hemispherical projection or post is exposed. The arch of the foot may be placed over the hemisphere and weight gradually applied to the foot causing the foot to assume an arcuate shape which stretches the tendons and muscles of the foot.
