Exercise can improve your health, but more isn't always better. Here's how to increase your physical activity level safely.
. Additionally, after finishing your workout, a cool-down period in which your heart rate gradually returns to normal should be part of your routine.
Like so many things in life where moderation is key, the Goldilocks zone for healthy amounts of cardiovascular exercise lies between two extremes. This meta-analysis shows that between the two extremes of being a sedentary couch potato or an obsessively-driven exercise fanatic, there's a sweet spot or"dose-response" of cardio training that's just right.
Warm-up before exercise by doing the planned activity—such as walking—at a slower pace to let your heart rate rise gradually.If you are currently inactive or sedentary, start by walking slowly on a level surface for 6-8 weeks, progressing to walking up hills, jogging, or taking part in more vigorous activities.
Lower the intensity of your exercise when specific environmental conditions put more strain on the heart.
