Result for: Sub-LT intervals

After a 15 or more minutes in zone 2, complete 2x20(5) in zone 3. Power may rise into zone 4 if possible, but HR should remain in zone 3 for the duration of the interval. 2 sets of a 20 min effort and 5 min recovery.

As a variation, cadence is maintained at 50-70 RPM for the duration of the 20 min interval. This further increases muscular endurance and cycling specific strength.
