There aren't any real directions with this table. My back is a POS, and I was told ten years ago I should get pins, rods, and screws in my lower back. Um no thanks. So I have dealt with this POS back of mine. Especially my lower back. I felt relief and improvement the very next day after proper use. Key thing is "proper use". After I figured out how to use it properly I felt relief. Do not stretch your back for more that 15-30 seconds. I made the mistake of holding pressure for ten minutes. That was dumb. I couldn't get off the floor without help. I could barely walk after I got help up. Then next day I was fine but pulled my back and well....FML I didn't use this table for two months after that. After extensive research, I found the correct way to use this device. First of all. Never use pressure more than half your weight. But at first start off light and work your way up. Start at 20-40 lbs psi. After a couple weeks go up another 20 psi. Listen to your back. Strap yourself in and pump it to the desired pressure and hold it for about 15-30 second max. Then release the pressure for the same amount of time or maybe even a little more. So like 30-45 seconds of no pressure. Then repeat. For the first week I would recommend no more than 10 minutes and increase your time by five minutes each week until you reach 30 minutes max. 20 years I've had a POS back and this is the only thing that has helped. I tried the inversion table and it became a paper weight. It just wasn't for me. I love this thing. I use it five times a week. Consistency is key. Doing it once every now and again is not going to give long lasting results. I've been using this for a couple of months now, and I see myself using this for the rest of my life. If your back is prone to being pulled, I highly recommend stretching first. I do about ten minutes of yoga first. If I don't stretch first, I will mostly likely pull my back the next day. I hope this helps. Good luck!
