Training Tip: Stay aerobic for longer, stronger workouts
Do you know your anaerobic threshold?
Depending on your fitness level, your body's systems are able to process the waste byproducts of exercise and replenish your muscles for more work. You cross the anaerobic threshold when you exceed your body's capacity to keep up with the load and waste products like lactic acid accumulate and the muscles cannot be replenished.
Aerobic activity is relatively low level activity that can be sustained for long periods because your body's systems can successfully resupply the muscles with oxygen. Anaerobic activity is high intensity activity that cannot be sustained for long periods because your body's systems cannot resupply the muscles with the necessary oxygen.
