If you’re looking for a supportive bra for running, lifting, or cardio, you’ll want to choose a bra with a good fit. Try on several different styles and sizes to find the one that fits best. If you’re in between sizes, go with the larger size.
If you’re looking for a style that’s comfortable and flattering, go for a bra with a low back. This will give you more support while you’re exercising.
Finally, consider the material. Bras made from soft, stretchy materials are usually more comfortable than those made from stiffer materials.
