Yes, you can exercise if you have osteoporosis, but it's important to choose the right types of activities. Weight-bearing exercises like walking, dancing, and low-impact aerobics are excellent choices as they help strengthen bones. Strength training exercises using weights or resistance bands can also be beneficial in maintaining bone density. Flexibility exercises, such as stretching and yoga, can improve your balance and reduce the risk of falls. It's crucial to avoid high-impact activities and exercises that involve bending forward at the waist or twisting the spine, as these can increase the risk of fractures. Always consult your doctor or a physical therapist to create a safe and effective exercise routine tailored to your needs.
