Lets use me for example.. A couple/few years ago I was lean and strong.. Able to do 20 full pull ups, bench around 290 and deadlift over 400.
Now I am a fat out of shape slob, getting back into it I cannot even do 1 pull up and need to use the pull up assist machine to help me do 6
That said, is there such thing as muscle memory? Basically will it be easier to put the muscle back on as I once had or does it take the same amount of time as it did when I was fresh, no muscle at all..
