What is an aerobic and anaerobic exercise? What are the main differences between the two? Which do you prefer for yourself? Lastly describe an exercise for both that would fall into each category of aerobic exercise and anaerobic exercise.

Aerobic is defined as "living, active, or occurring in the presence of oxygen". So when it comes down to the difference between aerobic and anaerobic exercise, oxygen is the key determent. During aerobic exercise, oxygen supplies the body with energy to sustain the workout, involving continuous, rhythmic movements of large muscles for at least 20 minutes. During the initial 20 minutes, the body utilizes carbohydrate and its body stores (known as glycogen) as its primary fuel source. After 20 minutes of constant movement, the body starts to burn body fat to power the muscles and body, also known as "aerobic fat-burning." Aerobic exercises include jogging and running, brisk walking, cycling, dancing, and canoeing.

Anaerobic exercises rely on energy breakdown from muscle stores rather than oxygen supply during aerobic activity. Even further unlike aerobic exercise and their constant flow of movement, anaerobic exercise is short in duration at high-intensity levels. But the short bursts of high-powered exercises are less able to be carried out for more than two to three minutes at a time, thus requiring breaks within repetitions to "catch your breath." Such anaerobic exercises include sprints, high jumping, diving, and high-intensity interval training. Interestingly, all exercises start out as anaerobic exercise as the body starts to undertake and adapt to the workout. Activities such as basketball and soccer also tend to require both anaerobic and aerobic fuel sources."
