What I've found out, after going from a pretty damn athletic lifestyle (10+ years of boxing) to turning into a full-fledged couch potato (smart working, working from home, pandemic, accumulated injuries preventing me to exercise regularly), is that the body is pretty forgiving as long as you keep it under a constant exercise routine, but it suddenly starts taxing you as soon as you become sedentary. Pretty recently I've taken a photo with a colleague coming to visit my hometown, and I couldn't recognize that fat f#@k in the photo which was supposed to be me.
