Being a bodybuilder, I hoist heavy weights all the time; a major stress especially when it comes to squats. I ordered the boots when I realized I had shrunk to 5'10.5" from being 6'0.5". I was thusly very happy when after approximately 5 weeks of hanging (5 times a week, 10-15 min intervals) that I am nearly back to my original height (6' 0.25"). I highly suggest this product as a supplement to good [emphasis on good] chiropractic care.
To those who have/will order this product, don't be discouraged if it seems to hurt your back at first; that's totally normal because your back is trying to readjust while the discs [which cushion the vertebrate] start rehydrating. Also, it will take some time to find the strap tightness that's right for your legs. Generally, tighter on the top strap and looser on the bottom is a good combination.
p.s. Hang from a real pull-up bar and make sure you have someone to spot you if you are not strong enough to pull yourself back up the bar to unlatch yourself.

I tried a couple of inversion tables but found that they weren't very comfortable on my ankles. Note: It is important to only buckle these gravity boots as loosely as you can without slipping out of them for maximum comfort (transfers pressure off achiles tendon and onto heal bone.) You can use these gravity boots with some inversion tables, but If you have the strength/coordination you may find that hanging from a bar (teeters brand) allows for more options (more hip/body movement.) Scientific studies have shown that traction is of questionable benefit, so I never bothered to persue inversion as the mechanism at play is obviously traction. However, recently, after many many years of back pain, I've started a program of inversion. I find that out of all the things I have tried (of which there are a great many), the inversion is probably the most beneficial. It hasn't cured me by any means, but it has provided some improvement. I think one thing to stress is that it is not sufficient to simply invert and lay still. Rather, it is probably much more beneficial to alternately contract the abdominals in a way that shortens your spinal length by aprox an inch or two. As if you are trying to pull your belly button up into your pelvis. or pelvic bone down into your belly button, perhaps? Do this every five or ten seconds. Not only will this strengthen your abs, but it will also fatiuge your stabalizing muscels so as to more fully stretch the spine (the abs, if not fatiuged, probably limit the stretch, as they are trying to protect the spine and hold it in place.) Also, by contracting and relexing the abs, you are likely expanding and contracting the disc space, moving fluid around the connective tissue (which has no real blood vessels of thier own.) Lastly, by doing these contractions, you may in effect be loading and unloading the spinal ligaments, which might strengthen them the way a bicep is strengthened by contracting and relaxing through bicep curls. There are many people, myself included, who believe that weak ligaments are the primary culprit in many lower back problems (even if bad discs are present....ie, many people have bad discs without problems, as shown by MRI studies.) In my case I believe it is my Sacroiliac joint ligament (si joint dysfunction.) I'm quite convinced that my improvments are not placebo in origin, as I was quite pessimistic about trying this (due to studies on traction that had me convinced this was fairly futile.) In addition to the abdominal contractions, I'd also reccomend do full inverted situps, hula type hip rotations while inverted, try to stretch the front of your hips (flexors) while inverted, and also twisting and side bending motion. It is probable that all this motion and stretching while inverted ads flexibility and elasticity to the connective tissue as well as moves fluid around. I invert twice a day for ten minutes each time. 5 stars

I wanted one of these for a long time. I just didn't know it. I always loved the Hangup Boots, but never bought them because I didn't want the big inversion table. Then I woke up one morning with a drive to get the boots and just find something (a jungle gym perhaps) to hang from. And then I saw this rack that hangs in your door. It was perfect! It installed easily in my studio doorway. It can be used for pullups or just something to stretch out with everytime I walk in and out of the room. Our daughter is constantly climbing on it and inadvertantly getting great exersise. I did get the inversion boots as well and try to find ten minutes a day to hang upside down. It gets blood to the brain and takes pressure off the spine. You can get a totally different work out being inverted. I highly recommend this to everyone, but especially fellow yogis. Yoga is great for working out back problems and this rack (paired with the Hangup boots) really helps with strengthening and lengthening the back. Cobra pose without a floor!
I am glad I didn't hessitate in getting this. I use it everyday. 5 stars

I got these along with the conversion bar for use with my teeter inversion table. I am getting over a broken foot so the stock method that the teeter inversion tables use just hurt my foot too much to use so I figured the boots were the way to go and so far I'm not disappointed.

First off these things are very comfortable. Ive used a body-solid brand of boots and these are far more cushioned and comfortable than they were. The key is to get them adjusted right when you use them. They don't need to be tight at all, just snug and they are great. So for comfort they get an A+.

Ive seen reviews that say these boots don't fit larger than average lower legs. I really don't get this, I have decent sized calves and they fit easily. I cant imagine how big your lower legs would have to be to make these too small but I will just point out that there's a weight limit on these and if they are too small you might want to check out the scale and make sure you can use these safely at your weight.

A few negatives. First off the things sort of feel cheap. They are just plastic and I guess to hang upside down Id of felt a little better to see some metal parts on there. The body-solid boots seem a lot more durable in that regard, the hooks and the fasteners are both metal and it gives more confidence in the durability. On these the hooks are plastic, the body is plastic, the fasteners, they just don't inspire a lot of confidence. I'm sure they will hold up because they aren't going to sell something that wouldn't but Id just say there's more durable options out there.

Overall I'm happy with them, they are comfortable enough to feel no discomfort while inverting and that's the idea. I use them with an inversion table with the conversion bar but I'm sure they are just as good with any of the bars they sell to hang on. 4 stars

I do upside down situps with a 50 pound vest on and a 25 pound dumbell in each hand. I weigh 185 pounds. No creaks bends or falls, great product 5 stars
