If possible, try to do a mix of activities that improve your aerobic fitness, balance, strength and flexibility. Becoming active for the first time or returning to activity during or after cancer is not always easy. If you are going through treatment, you may find it useful to plan your activity around this. Or if you usually feel very tired (fatigued) at a certain time of day, avoid planning activity for this time.
Think about what you are most interested in doing and what you would enjoy the most. You could make a list of the different activities you and your family and friends could try. There is not a single activity that is best for everyone. The important thing is to choose something that fits in with your life.
