Aging, pregnancy and vigorous exercise can all lead to the dreaded sagging bust. While exercising the muscles beneath your breast tissue cannot physically lift your breasts, building up the muscles can help keep your chest looking lifted. To prevent future sagging, always wear a supportive sports bra when you exercise.

The muscles of the upper back may not get as much attention as six-pack abs or stellar legs, but they’re just as important. If you’re worried about adding too much bulk, stick with one to two sets of eight to 15 repetitions of each exercise, suggests the American Council on Exercise. Whether sporting a bikini for a day at the beach or that little black dress for a night on the town, a toned upper back helps you make a memorable exit.

From sagging breasts to knee pain and injury, women face a different set of exercise challenges than men. Regular strength training can help improve bone, ligament and muscle strength, reduce your risk of injury, make daily tasks easier to perform and help you prevent or treat some common problems faced by women. Move your workout to the machine weights for added safety and convenience.

While weight gain may be dirty words for most women, being underweight can have health consequences just like being overweight. You are at a higher risk of tuberculosis, respiratory diseases, digestive conditions, certain types of cancer, infertility and birth defects after pregnancy. Many factors influence your ability to gain and lose weight, and by modifying the ones you have control over, you can gradually add weight at a healthy rate.
