I’ve noticed that when I took a decon break that even pumping seemed to interfere a bit with tissue softening, at least based on responsiveness when i started back to elongation training. Granted, it has been a while since I took more than 2 weeks off, so maybe a longer break is the thing and not the pumping.
Another thing I’ve noticed is that when I’ve been more focused on girth work that I seem to lose some BPEL length after a decon. That is I took a few week break from length work and focused on pumping and clamping and though I gained girth I did lose some BPEL from my peak. I’m still trying to get back to that record length and it’s been several months.
N of 1 and all that, so maybe it will be different for you. But if you go that route, I’d be interested to see how your girth focus affects your BPEL and your post-decon length responsiveness. If you figure out a way to be more successful than me I’ll give your way a shot next time.
