Exercise is essential to a healthy lifestyle, but some guidelines should be applied in order to exercise safely after breast cancer. 1. Talk to your doctor about your decision to start exercising. Ask: - Do I need to take any specific precautions to avoid lymphedema? - I'm thinking of doing these kinds of exercises. Will they be too much for me? - How can I modify my exercise to make sure I don't overwork myself? - What are some movements I should avoid? 2. Start slow and steady. Focus more on proper form than lifting as much weight as possible or doing things as quickly as possible. 3. Don't forget to warm up. 4. Don't forget to cool down. 5. Take rests if needed.
