Pumping on rest days

I just made my new pump. It’s a variation on the theme Proaquatic™ gravel cleaner and Mighty Vac brake bleeder (I’ll post the setup when ready). I was running some tests and wonder whether moderate pumping is a good strategy on the days off, since I was on my second day off from jelqing and stretching. I reasoned that increasing both the blood flow and exchange through a succession of 5 min. pumps might be an adequate practice on days off. Any comments?
