I'm a 56-year-old woman who had never heard of or seen an inversion table until two days before I ordered one. I have purchased products within the past month aimed at making a "home Physical Therapy" room for myself, rather than a home-gym. I believe already that if I had purchased the inversion table alone, I would have bought all I need. The relief from the reverse gravity is...unbelievable. Although I was so nervous (and still am) inverting, and although I would never think of inverting totally, I found myself yawning as if ready for a nap on my very first inversion. I suppose it's the infusion of blood to a head that suffers from vertigo, but nothing--no exercise, no pill, no massager--has provided the relief that this Ironman has.
HOWEVER: I'm concerned about the ankle supports. While I think anxiety about the supports is natural, I have experienced what I'll describe as "wiggling" the further I invert. This of course is natural, and a review above states that you should point your toes (rather than clench them in abject terror :). But even for those who are understandably afraid, the wiggling is the cause of some slight concern for me.
That said, the wiggle isn't nearly discomforting enough to prevent a 45-degree inversion. I have gone to a 60-degree angle and frankly don't feel comfortable at that degree. First, I found that my head was sliding off the top of the unit. I subsequently raised the height-scale two full inches. (I'm 5'6"-and-a-quarter, and I raised it to 5'8").
