The exercise device includes a one piece member having upper surface and a lower surface. The lower surface has an arcuate section designed to directly contact a floor. The arcuate section is located between first and second planar sections. Each of the first and second planar sections is inclined downward at an angle relative to the arcuate section. A pair of spaced apart ramps is formed in the upper surface and each extends downwardly from a back surface to a front surface. Each of the ramps is designed to receive a portion of a person's foot while an adjoining heel of each foot rest on the floor. The person can rock the exercise device back and forth by shifting his weight from one foot to the other.
