That's an excellent goal, but the minimum amount of exercise you need is actually less than you might think.
Get a heart rate monitor.
Ask your doctor if they have a recommended heart rate range for you.
If they don't, I suggest starting at 60% to 70% of your maximum heart rate (HR).
Many people think they need to set intense goals, such as doing five-hour workouts per week or training to run a half marathon.
