If you are just starting an exercise routine, here are some low-impact aerobic options and tips to do so safely: choose dance classes that keep one foot on the floor at all times and warm up properly; wear supportive shoes and don't overexert yourself in classes by alternating movements; be aware of your limits while dancing and maintain good posture. Vigorous sports like basketball and racquetball can be difficult for those with pain, so take precautions.
