And don't overdo any exercise to the point where you sweat.

Actually, breaking a sweat is a good thing, it releases toxins (through the skin), lactate acid built up in the brain & muscles (inhibits free radicals). Growth hormones released from HIIT workouts benefits breast growth. Bottom line, depleting muscle expenditure is good for NBE, e.g. isometrics breast exercise, helps breast growth despite misinformation presented out there.

plus exercise produces endorphins !!!
