This thing is awesome! Yes, it can hurt especially on those really tight areas but I love it anyway. You can feel the blood start racing through your body, great for circulation. Takes a few minutes to adjust your body to the right position when laying on your back. I lay on it all different ways. Pull your legs up when on your back to get the middle of your back and spine, I love standing on it, the hip area hurts but I do it anyway. If you're really a trooper kneel on it. I use it almost every day and I only wear underwear when i use it. This was a great price and it came with a neck pillow. I've ordered more for friends.
