Young adult. It takes about 1-2 weeks to notice a trend. I'm just looking over my summer RHR data and it pretty much matches my activity level. Steady decline in May and June when I was working out consistently. Steady climb after I injured my knee and had to lay off a bit. Decline when I got back on the exercise horse. Incline towards the end of the summer when workouts became rare due to wrapping up projects and traveling. On a good week, I'll do 1-2 hours of cardio 5x a week, maybe with some HIIT thrown in. On a bad week I'll do nothing.
