I use it every day or EOD, depends. Spine alignment is a wonderful thing. If it werent for the blood rushing to your head I would hang upsidedown for an hour.
Inversion tables arent a past fad. They are legit and really help.
My wife has degenerative disk disease and 10 years ago could barely get through a day of work, let alone lift anything or bend over.
Constantly shoveling anti inflammatories and muscle relaxers.
I bought her a table and she used it twice daily for 3 months and she was as good as new. She runs, lifts very heavy things (100 lb + from the floor) for her job...... no problems since.
