Exercising is hard for me because I'm very heavy-chested and I get sore. What can I do to keep in shape without hurting myself?

Consider investing in a good, supportive sports bra. The right sports bra will help keep breast-bouncing to a minimum and reduce soreness. You may want to be professionally sized so you are sure to get the right fit.

If a sports bra doesn't help, try an activity like swimming or water aerobics, where there is little or no stress placed on your chest. If you don't have access to a pool, try low-impact activities like walking, yoga, or riding an exercise bike.
