A closer look
Gaining skeletal muscle mass physically adds brand new nuclei to your muscle cells, and these microscopic control centers permanently remain in your tissues even if you stop working out and lose all your hard earned strength. This brilliant biological phenomenon is the actual scientific basis for muscle memory, explaining why it is significantly easier to regain lost muscle than it was to build it the very first time. You can aggressively abandon the gym, sit on the couch eating potato chips for three straight years, and your previously swole muscle fibers will still hoard those extra nuclei like tiny, optimistic preppers waiting for the glorious return of heavy dumbbells. It is a rare example of the human body actually cutting you some slack, graciously saving your biological progress just in case you ever decide to stop being incredibly lazy and eventually return to lifting heavy circles in a crowded room
