A stretching device that facilitates wall-based stretching by creating a vertical surface for a user to press against. The stretching devices include two primary components: a stretching board and a base board. The stretching board can couple with the base board such that the stretching board and the base board form a right angle to each other. To use the device, the base board is placed flat on the ground with the stretching board sticking straight up. Stretching boards are designed to withstand forces of use without excess flexing.
