Subject: RE: Bike interval units questionSet #1 20m / 6.00 miles VO2 Max Intervals: 20x0.5' on 0.5' rest Perform these intervals at a maximum effort that you can sustain for the interval duration. Do your best to maintain a cadence higher than 90 rpms. What you do is 20 intervals. 30 seconds max effort THEN 30 seconds rest (easy spinning) - this is one minute total. Do this 20 times so it will be 20 minutes total. |
