Hi all -
I've tried to search through the threads, to google it, and to look on YouTube - but no luck.

There's plenty of advice about short term applications like riding a bike, or taking a week off of training - but what I'm trying to understand is about after a layoff.
Why is it easier to gain strength (or size, for that matter) and it's quicker than when you did it the first time?
Thanks for thinking about it!
