Run easy to get fast?

Training Zones

At practice, I've talked a little bit about the fact that there are different physiological processes that your body relies upon to produce energy and that the greatest factor to improving those processes is to spend TIME working at the level that maximizes each process.  Take a look at this video, to help you understand how endurance athletes use TRAINING ZONES to help determine how hard they should be running (or riding in this case)

Zone 2 Training Benefits

Watch this video to help yourselves understand HOW training only at a lower intensity can lead to increased performance at a higher intensity. 

FYI.  In this video, they are using a 5 zone model. When I plan a lot of your training, I think in a 7 zone model.....no biggie, zone 2 is still the same in the 5 and 7 zone model. 

Your homework.....explain this graph

Your other homework......tell me how to find your training zone 2 and training zone 4.  (Hint, look at around the 12 minute mark on the first video)
