I tried my table a couple of days after I got it. It was strange to be upside down, but I felt secure whith the ankle supports. I've kept it open because it looks like I would hurt my back trying to open and close it every time. I did feel really good relief on all parts starting on my knees, hips, lower back, even neck. I had lower back pain for a long time. The first day I used it, the pain was gone. Sure I felt a little sore because it obviously causes a stretching of joints and muscles. But after that was gone I felt no pain. My right hip was also giving me trouble. The chiropractor would have problems setting it in place. Some times I couldn't even get up from sitting without it hurting so bad that I couldn't walk. This pain is gone since I've used it. It's worth the investment. I don't feel like going to the chiropractor so the table has paid for itself. I do kettlebells workouts, some times with 50 lb weights, and that would tighten up the muscles on my back. (I'm only 115 lb). I can jump right on after a work out and stretch like I could never do with any normal stretching routine. Definitely would recommend it.
