A calf stretching device that helps to increase flexibility, improve posture, and promote rehabilitation of lower leg injuries. The device generally includes a wedge-shaped central ramp having two contiguous sections of different lengths joined end-to-end to define a triangular ramp. The long section is defined by two planar surfaces inclined together along at a centerline at an outside angle of approximately 210 degrees. A pair of opposing substantially triangular side panels flank the central ramp and protrude outward beyond the long section and short section to align the feet and stabilize the device. A built in adjustable flip-out riser may be included for more ramp inclines. The device seats atop a door frame and can be used In two orientations, one that ramps up at 25-35 degrees and a second at 55-70 degrees.
