Abstract:
1. An exercise device for facilitating blood circulation in the lower extremities of a person's legs and feet, comprising: a) a one piece member having a longitudinal central axis and a transverse central axis, said member having an upper surface with a first side edge spaced apart from a second side edge, a lower surface having an arcuate section designed to directly contact an underlying support surface and having a midpoint located on said transverse central axis, said arcuate section is located between a first planar section and a second planar section, said first planar section having a distal end joined to said first side edge and said second planar section having a distal end joined to said second side edge, each of said first and second planar sections extending at an angle to said longitudinal central axis and inclined downward relative to said midpoint of said arcuate section, and a front surface and an oppositely aligned back surface each positioned between said upper and lower surfaces, wherein said front and back surfaces each has a predetermined surface area, and a hollow area is formed in each of said front and back surfaces which represent at least about 30% of said predetermined surface areas, and a rib is formed between said hollow areas that extends along said longitudinal central axis; b) a pair of spaced apart ramps formed in said upper surface and aligned perpendicular to said longitudinal central axis, each of said pair of ramps extending downwardly at an angle from said back surface to said front surface, and each of said pair of ramps designed to receive a portion of a ball of a person's foot while an adjoining heel of each foot rests on said underlying support surface, whereby said exercise device can be rocked back and forth about said midpoint of said arcuate section and parallel to said longitudinal central axis when said exercise device is placed on said underlying support surface and said person alternates pressure applied by said ball of each foot; and c) a central abutment formed in said upper surface and positioned along said transverse central axis, said central abutment ensuring that the person's feet do not slide off of said pair of spaced apart ramps.
