Why Is the Slant Board the best choice for stretching and excreting? A slant board is a flat-surfaced device made from durable wood or lightweight plastic material and is used to keep our muscles and tendons in perfect shape. By standing in a slant position on this board, you improve the performance of your muscles for exercise and cut down on cases of injury. If you're an athlete or someone suffering from Achilles tendon injuries, this board will help to relieve the pain. You can adjust the board to different measurements (15, 20, 25, 30, 35 degrees). This makes it easier to increase stretching to higher levels. Using a slant board allows you to protect the Achilles tendon which is the strongest tendon in the body. It's also useful for relieving the stress around muscles which tend to ache after exercise. Preventive medicine also values slant boards to ensure that possible leg injuries are avoided. A slant board helps in the circulation of blood to the leg to prevent swellings.
