if you’ve ever played organized sports, we call it “conditioning”
You are just getting your body used to elevated levels of work. Just like your legs get used to running so does your heart. It doesn’t need to get bigger to do so.
If your body is used to exercising…..every day activity is a cakewalk for it.
Unless you’re putting in olympic level training 6-7 days a week, you’re not gonna have a problem.
