Weight-bearing exercises such as walking, jogging, dancing, and aerobics are all fine. Try to exercise for at least 30 minutes 3-5 times a week. This will also increase muscle strength and coordination and thus reduce your chance of falling. If your health does not allow this much exercise, check with your health care provider. If you are on any of these medications, you should discuss with your health care provider whether you still need to continue these medications.
Smoking is bad for many conditions including osteoporosis.
Your health care provider can give you information about quitting. If you are concerned about osteoporosis, you may wish to limit your alcohol intake to one drink per day for women, two drinks per day for men. Consider drinking less than two caffeinated drinks per day, and not eating meat more than three times per week. But if you do reduce your meat intake, make sure you still have a balanced diet. Most people do not get enough calcium.
