How many squats should a female do daily for a bigger butt and how long until she sees actual results?

You could do a series of squats several times per day, gradually increasing the number of squats in each interval (say 10, then 15, then 20) and the frequency of each interval. Even if you regularly do squats, depending on your genetics, you may not ever get the size butt you want... but, squats will certainly help!
