PJ: as all workouts and exercise it's a personal thing and do what is best for you and what you like to do is also important.
one of my most used and favorite pieces of equipment is this TEETER UP inversion table
https://teeter.com/product/fitspine-lx9-inversion-table/ that I just picked up about 6 months ago.
i've been using an older version that was actually invertalign inversion table that TEETER UP now owns and this is their latest version. I started hanging about 2005 cause I didn't want to take ADVIL daily for sore back and I learned to hang 5 minutes a day (no fancy exercise while hanging like Mr. Teeter does) and just a full hang.
it took me about 2 weeks to build up to the 5 minutes cause my old 6'3 225 frame body had the ill effects of age, a lot of golf and gravity. once I did I now play a game of suduko while hanging.
I haven't taken any ADVIL for back pain since I started hanging (only for a headache if maybe I ate or drank the wrong stuff or now a little knee pain) and i'm sure my kidneys are happier. I used to buy the 100 Advil gel tablets every 2-4 weeks at Costco before hanging.
the chair I gave you a link for goes on sale for $50 off now and then, but even at full price if you have a sore back and can and are willing to hang to fix it that price is a lot cheaper than pills or surgeries. there are a couple threads in free parking where we talk about inversion tables if you haven't tried it.
good luck with your body and of course the gym and the boys which all should be a fun ride as you get on this train of life.
cheers (I also drink a gallon of homemade ice tea daily which maybe has a little to do with the amount of posts I make and extra energy)
