Abstract: A reversible walking slide mill for a person seeking walking or jogging exercise has first and second plastic molded slide mill platforms horizontally interlockable to each other in side by side arrangement as for one platform for each person's foot. The platforms are disconnectable as to reduce width when in storage or transportation. A smooth slippery foot sliding surface is on top of each platform having an uphill inclined front surface and a rear surface shorter than the front surface with a flat surface therebetween. A pair of extensible rotatable gripping handles are mounted to each of the platforms for gripping and rotating by the person during exercise. Resilient feet on the bottom of the platforms provide vertical shock absorption, flexibility and recoil independently to each platform when a person is exercising on the slide mill platforms.
