It all depends on the time frame from when you sustained a heart attack. It is important to get your cardiologist’s or other physician’s approval for you to start any exercise program. When you have a heart attack, your heart may not function as well as before the heart attack. Your heart may be weakened, so it will take time to build it up to exercise at the same level you exercised before.
You need to have a physical before you begin a program and follow the physician’s recommendations for safe progression. If you begin to experience any chest pain, stop immediately. For good heart health it is recommended that everyone exercise at least 30 minutes a day, most days of the week. The 30 minutes can be broken down into 10 or 15 minutes segments if 30 minutes is currently too difficult for you.
