If you’ve done cardiac rehab, then you likely already have learned an exercise regimen. It’s nice when you’ve had that benefit, because you can slowly start going back to the regimen that you had before.
If you don’t have the benefit of a guided regimen in the past, then you can start by walking 10 or 15 minutes a day and do that every day for the first week. Increase that to 20 in the next week, then 25 the next week.
Once you hit 30 minutes of walking a day you can start doing a faster walking pace, and then eventually you can start jogging. Be sure to consult your physician, of course. You always want to talk to your doctor and make sure that it’s safe for you to exercise.
