Here are some questions to ask your doctor:
Start slow. Even if you only do a few minutes of activity a day, it will help. The amount of time spent being active can be slowly increased. Your muscles will tell you when you need to slow down and rest.
Try short periods of exercise with frequent rest breaks. For example, walk briskly (or jog or run, if you can) for a few minutes, then slow down and walk at a slower pace for 1-2 minutes before picking up your faster pace again. Keep doing this until your fast-paced activity totals to 30 minutes. Even if you have to divide the 30 minutes throughout your day, you will still get the benefits of the exercise!
Include exercises that will help you keep lean muscle mass and bone strength like exercising with a resistance band or lightweights. If you do not have exercise equipment, there are many ways to use your own body as resistance (push-ups, crunches, squats, and lunges are perfect examples).
Include exercises that will increase your flexibility and the range of motion in your joints. Being flexible and having a good range of motion also protects you from injuries while exercising and can improve your exercise performance.
Start all physical activity with a warmup for at least 2-3 minutes. This includes toe tapping, shoulder shrugs, marching in place with high knees, arm circles, or jumping jacks.
Remember to match your breath to your exercise. The part of any exercise that requires exertion is when you should be exhaling. For example, during a lunge, inhale while you lunge down and exhale when you come back up; during a sit up, inhale when your back is on the floor, exhale when you sit up; for running, try to keep a steady inhale/exhale breathing pace instead of taking non-rhythmic, short breaths; while stretching, exhale while you try to go deeper into the stretch.
Finish any physical activity with 2-3 minutes of stretching. Hold each stretch for 15-30 seconds. Examples of stretching are reaching overhead, deep breathing, and bending over to touch your toes.
