Once you have the ok from your doctor to start a training program you can start with the following:
1. buy some good running shoes and start jogging slowly for 1 to 2 miles.
2. If you have a bicycle you can start riding 10 to 15 miles at a slow pace to start working on your legs. If you start to get a burn in your legs, slow down.
3. start doing body weight squats, push ups, crunches and flexibility exercises.
