Muscle mass matters. Low muscle mass is associated with outcomes such as higher surgical and post-operative complications, longer length of hospital stays, lower physical function, poorer quality of life, shorter survival, and a predictor of poor morbidity and mortality.
Even your DNA remembers the muscles you’ve once had. A 2018 study found that, even after detraining for several weeks (and potentially years), your “epigenetic” ability for building muscle isn’t lost, i.e., if you were fit once and lose it, you can get fit more easily the second time around.
