Anyway - go to Myer or the like and get properly fitted. Berlei & some other manufacturers make bras rated for different exercise so you will need to get the one rated for high intensity workouts.

Hi
i would recommend Bras n things over myer for fittings as they are heaps better and more trained to fit. they have a couple really great sports bras and can make sure you are in the right one.
