Hmmm, good points. I think I have to buy a chair with a hole in it or something because standing up for all that time while hanging is a pain in the ..., well you get my drift haha
You just sit on the edge of your chair and it hangs down without touching anything. I hang every day while I sit at my desk, on my laptop. It couldn't be easier! If you want to do btc, you just rest your feet on the desk, kick back and watch an episode of something.
With regards to the original post... I think the main point of hanging every day is so your ligs don't have time to toughen up as much. I wonder if manual stretches cause the same sort of stresses as hanging. I doubt it.
I've been doing PE on and off (mostly off) for about 8 years and never really got anywhere with it. Anyway I've been hanging for just over a month now and it's the best, easiest, most convenient method I've ever tried - and I've tried them all! As long as you have the privacy which I didn't for all those years. I've not made any measurements yet but I can tell it's working.
