If you have osteoporosis, you can do low-impact exercises such as walking, yoga, and tai chi. These activities can help strengthen your bones, improve balance, and reduce the risk of falls. Additionally, light strength training can help build muscle to support your bones. However, you should avoid high-impact activities like jumping or running as they may increase the risk of fractures. Remember to consult your doctor or physical therapist before starting any new exercise program to get personalized advice.
