You're aiming for moderate intensity when you exercise, but how do you know if you're achieving it? You're probably exercising at moderate intensity if you're breathing faster and you break into a light sweat after about 10 minutes of activity. If you're not sure, try the talk test: If you can carry on a conversation but you can't sing, you're probably exercising in the moderate-intensity range.
