A significant factor in maintaining a healthy weight is exercise. Many health risks can be greatly reduced just by following exercise recommendations. Current recommendations say that adults should get the following levels of exercise:
2.5 hours/week (moderate intensity)
75 min/week (vigorous intensity)
Moderate intensity includes activities where your breathing and heart rate are noticeably faster, but you can still carry on a conversation (walking briskly or biking at a casual pace). Vigorous intensity activities are when your heart rate is increased substantially and you are breathing too hard and fast to carry on a conversation (jogging, running, and most team sports).
Body Mass Index (BMI)
Body Mass Index, or BMI, is a test used to assess your body composition based on height and weight. The following categories are used when assessing BMI.

Your waist circumference is another risk factor considered when assessing weight. You may be at a heightened risk for conditions related to obesity if you have a waist circumference of or greater than 40 in. for men and 35 in. for women.
Body Fat Percentage
Body fat percentage is another way to assess your body composition in addition to your height and weight. Below are the categories used to determine your health based on body fat.
