You can stretch your hamstrings from your calves. You can also place it under your back or neck to stretch your back muscles. The angle is adjustable, so it can be used even by people with stiff bodies. It has a shiatsu board specification, so it feels good as it stimulates the soles of your feet while you are on it. I used to use it for rehabilitation after suffering from a herniated disc. I bought it and used it after being recommended by a physical therapist, and it's really good!! It is said to be good for sciatica because it is expected to stretch the nerves. It's a simple machine, but I recommend it because it worked for me if I kept using it.
