That is interesting and it makes sense to me too. When I started refeeding last year I basically stopped exercising because Matt had said it was important to rest plus I wasn’t seeing any results from it. Months later when I tried to start I couldn’t believe how hard it was to get back into it without crashing. I am sorry I stopped because I’m still not where I want to be. Sometimes my back goes out on me for no reason that I know of. I can’t do anything until it subsides except to try to walk around a bit to work the stiffness out.
