This week's 45-minute workout goes back to some longer intervals: "Over/Unders".  These are 12-minute intervals that include 1 minute "Over" threshold, and 1 minute "Under" threshold.  Throughout these efforts, you are getting the benefit of the intensity at the higher resistance, you are training your recovery during the "Under" minutes, and overall, each 12-minute interval averages an intensity within the threshold range (1st interval = 90%, 2nd interval = 95%).

​

This workout might be challenging to do outdoors unless you can find a long/flat stretch of road without intersections.
