Answer:
B. anaerobic activities
Explanation:
Heavy weight lifting is an exercise, so it's not a lifestyle or sedentary exercise off the bat. It's anaerobic, and here's why:
<u>Aerobic</u> means "requiring oxygen." This includes long-distance exercise, like running, where you're actually traveling a distance.
<u>Anaerobic</u> means "not requiring oxygen." This includes heavy weight lifting, because you're mostly stationary.
<u>Sedentary</u> means "sitting down." It's like me sitting in front of my computer all day.
<u>Lifestyle</u> is like everything else; fun things that contribute to your lifestyle.
