Anaerobic exercise is high-intensity, high-power movement that requires your body to expend a lot of energy in a short period of time. Things like weightlifting, jumping rope, sprinting, and high-intensity interval training (HIIT) are examples of anaerobic exercise; if you take these movements to the battlefield, you’re looking at carrying a battle buddy to safety, running ammo cans between one truck and another, or throwing equipment over a wall so you can get cover from enemy fire. This kind of exercise pushes your body to demand more energy than you’d need for aerobic exercise, like running, and it relies on energy sources stored in your muscles.

Aerobic means “with oxygen,” and anaerobic means “without oxygen.” Sure, you still need oxygen to perform anaerobic exercises, but not in the same way that you do for aerobic exercises. Aerobic exercise uses oxygen to produce energy so your body can use fat and glucose for fuel, while anaerobic exercise can only use glucose for fuel. Glucose is available in your muscles for quick, short bursts of movement, and you get it through a process called glycolysis.

The Sprint-Drag-Carry is a prime example of how the Army tests your anaerobic fitness. Check out Chapter 8 for a wide range of exercises that can boost your anaerobic power.
