Slow and steady wins the race. Trying to do too much too soon can leave you discouraged or even injured.
One way to pace yourself is to count your heart rate and make sure it stays below a certain level. Another is to rate how difficult exercise feels and avoid too much huffing and puffing. Your health care team can teach you how to avoid pushing yourself too hard.
Step up your workout as you become more fit. Gradually increase how long and how hard you exercise. For instance, you may start out walking for just 5 or 10 minutes. Over many weeks, you may build up to 25 or 30 minutes. Work your health care team to adjust your exercise, meals, and medicines as you get in shape.
