I’ve been hanging (or trying to) with no rest days (trying to do it Bib’s way). I’ll have more to report in a few/several months. I just do an occasional light day (1-2x sets instead of 5-6x sets).
I do split sets lately, and I have noticed I heal pretty well in 12 hours. (if I hang morning, then night during a day, I can usually do my max weight, or some amount of increased weight at night).
Usually just 1 light day has the same effect as a rest day—the lack of fatigue allows me to heal & I am back at a higher maximum weight the next day.
I can’t think of any type of PE other than hanging where people don’t use rest days.
I left PE & came back due to injuries (not a PE injury, just a bedroom/wife thing). I gained .75” & lost it all, possibly due to repeated injuries, I am not sure. Stopping PE cold turkey definitely played a part in that. I have regained at least .5” so far (maybe more/maybe less). Not enough time has gone by yet, that’s why I don’t have much useful to report.
I know there was at least one guy hanging Bib’s way, but I haven’t seen him lately. I think he was doing a full 12x sets per day. I can’t recall his name… I would also like to know if the no-rest-days method was working for him or others.
