How does exercise help my bones?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)

Just as exercise improves your muscle, it also builds your bone strength. In particular, weight-bearing exercise, which is just about everything except swimming and cycling, really helps kick up the bone-building process. Bone’s biggest enemy--besides, perhaps, a patch of black ice--is soda (or pop, if you’re from the Midwest).

Chemicals found in soda, such as phosphorous, may lead to bone loss, and the caffeine may interfere with the body’s ability to absorb calcium. We suggest drinking low-fat milk or calcium-fortified OJ instead of soda pop! Your bones’ best friends are vitamin D, calcium, and magnesium. A solid 40 percent to 60 percent of your bone mass is deposited during early puberty (ages 10 to 12 for girls, 14 to 18 for boys), with an extra 10 percent added during your twenties. Bone density peaks by the time you’re thirty, with bone loss happening after that.
