Under Over Intervals - 5x9minutes w/4min RBI
Under Over intervals create a great overload. Forcing athletes to work above threshold and then settle in right below threshold, these intervals train your body to buffer exercise by products while still producing sufficient power.
Add these intervals to your quiver if you are a:
- cyclocross racer
- have a hilly event
- or have climbing events where you are force to go over threshold and settle back in.
