ANAEROBIC THRESHOLD / AT
Each person has an optimal training zone called their target heart rate. Charts you see showing target heart rates are actually just averages based on age and weight. The VO2 Max test will give you target workout zones based on your specific results. These zones give you the precise heart rates necessary to optimize each level of exercise and maximize your results. A VO2 test will also show the anaerobic threshold. The body can supply adequate oxygen to the muscles up to a certain exercise intensity level or threshold. This threshold is called the anaerobic threshold (AT). Known as the red-line to endurance athletes, this threshold is the highest intensity, as measured by heart rate, at which the body can remove lactic acid as quickly as it is produced. Just below anaerobic threshold (AT), an athlete is working hard, but feels no burning in the muscles and is breathing heavily, but controlled. Above AT, lactic acid is building up in the muscles and will cause premature fatigue. Knowing one’s threshold allows one to achieve a very high level of cardiovascular conditioning without the discomfort and muscle damage of lactic acid buildup.
Knowing your AT (and the associated training zones) and incorporating this into your training program is the single most important thing that an endurance athlete can do to improve performance.
The table below shows how fitness is assessed based on VO2max.

How will this help me reach my goals?
Once you start using our Personalized Intensity Training Zones, you will have workouts that are specific to your goals. You will drop those extra pounds, improve your body's ability to use oxygen, and increase your overall endurance - all without wasting time! If you're not training with specificity, you're working out in the dark. Too many people work out at the wrong intensity never giving their body the right stimulus at the right time. Too much too hard = overtraining and injuries. Too little too easy = no improvements and wasted time. Now you can train smarter with personalized training zones based on your anaerobic threshold.
