Maintaining a Healthy Body Weight
Your Body Type
• There is no single ideal body weight or body type
for everyone. There are 3 general body types:
– Ectomorph is characterized by a low percentage body
fat, small bone size, and a small amount of muscle
mass and size.
– Mesomorph is characterized by a low-to-medium
percentage of body fat, medium-to-large bone size,
and a large amount of muscle mass and size.
– Endomorph is characterized by a high percentage of
body fat, large bone size, and a small amount of
muscle mass and size.
Your Body Weight
• Overall body type is determined by heredity, but one aspect you
can control is your weight.
• One way to determine if your weight is within a healthy range is to
measure Body Mass Index (BMI.) This is a way to assess body size
in relation to your height and weight.
• Although there is no one ideal weight, there are healthy ranges for
each individual. They can be determined by:

Body Composition
• Body Composition is the relative percentage in your
body of fat to lean body tissue, including water, bone,
and muscle.
• Physical activity and nutrition affect body composition.
• Body composition has an impact on your overall
health.
– Excessive leanness is having a percentage of body fat that
is below the acceptable range for your age and gender.
– Overfat is carrying too much body fat for your age and
gender.
Weight Control & Physical Activity
• The more physically active you are, the more
calories you will burn. Yet the number of
calories you burn through physical activity will
vary with respect to several factors:
– The number, size, and weight of the body parts
that you work.
– The intensity of your workout
– The duration, or time, of your activities
