The CrossFit approach to exercise is to balance different exercises and types of exercises in such a way that helps you accomplish your fitness goals faster and more efficiently. The two basic types of exercises that CrossFit uses are aerobic and anaerobic.
Aerobic training is one that lasts for more than a few seconds. Examples of aerobic training include running and swimming. During aerobic training, your body uses the oxygen to release energy it gets from food by using a metabolic process. Anaerobic training lasts less than 90 seconds. Squats and bench press are examples of anaerobic activity.
Aerobic training benefits your heart and decreases the amount of fat in your body. Obviously, these are very important health benefits. Aerobic activities allow people to engage in low to moderate power outputs for prolonged periods of time, which is extremely useful in many sports. However, when you engage in excessive aerobic training, you start losing muscle mass, strength, and speed. Excessive aerobic training often leads to decreases anaerobic capacity.
Anaerobic exercise also helps you avoid the risks of heart disease and lose fat. It is unique in that it helps develop and improve power, speed, and strength. Anaerobic exercise also helps grow muscle mass.
Anaerobic exercise doesn’t have any adverse effects on the aerobic capacity of a person. A properly structured routine that includes both aerobic and anaerobic exercises can help a person develop a very high level of fitness. Examples of sports that require a lot of anaerobic fitness include basketball, football, boxing, and track running. In these sports, you spend the majority of your time performing anaerobic activities. Long distance running and cross-country skiing are aerobic sports. If you want to accomplish outstanding results in these sports, you will need to train aerobically at levels that do not give you what CrossFit views as optimal health.
