You'll recall from her registration form that Beth is a recreational athlete whose goal is to get in shape. She's 5'5" and weighs 140 pounds. She would like to lose 10 pounds and keep it off.

Beth really got motivated to improve her diet and to become more active after a recent physical. Her physician told her that her total cholesterol and LDL cholesterol levels are slightly elevated and that her HDL cholesterol is near the lower end of normal, as you can see in this chart.

Beth is concerned, but not panicked. She has resolved to eat better and to exercise more. She has a few questions for you about the role diet and exercise might play in improving her blood lipid levels.

What kind of exercise should I do to lower my total and LDL cholesterol and raise my HDL cholesterol?
a. endurance (aerobic) exercise
b. strength (anaerobic) exercise
c. either aerobic or anaerobic exercise
