Doctors and researchers recently came together to figure out the best ways for people with Duchenne and Becker muscular dystrophy to exercise safely. They found that gentle activities like light cycling and moderate strengthening exercises can help maintain muscle function and build strength without causing harm, as long as the exercises are tailored to each person and done with proper supervision. The key takeaway for families is that staying active with the right kind and amount of exercise — guided by a healthcare team — can be a helpful part of managing dystrophinopathy.
