It depends if you're pushing the muscle to fatigue each set (you cannot possibly perform another rep in good form). This will create micro tears in the muscle fiber. When they heal, that is when muscle is grown.
You'd probably want to finish 2-3 sets before taking a long break. So do 1 set of 8-12 reps, rest for 60 seconds, do your second set of 8-12 reps, etc. and then you can go back to whatever task you're doing at the time.
You can search for the exercise you perform and track it.

"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. It doesn't happen, what does happen is you get results. Lifting Barbie weights does nothing but waste time.
