Slant Board increases extension in the lower and upper back while stretching the calves. Board is made of a heavy-duty composite plastic. Angle of incline adjusts to 4 levels and folds flat (3-inches) to store easily. Levels are 0 degree, 5 degree, 15 degree, 25 degree, and 35 degree. The last slot on the board makes an excellent handhold for stretching.
