I recently listened to San Milan's video interview with Dylan Johnson, and I took away a couple of points he made about sub-LT1 training:
- working just below LT1 maximizes the lipolytic system activity
- if you do a hard effort during a zone 2 ride, you body produces hormones that turn off lipolysis, reducing the training effect
- if you want to include a hard effort during zone 2 ride, save it until the end of the ride
If I can only do 4-5 hrs/wk, lipolysis isn't my main concern because I'm not likely to be doing randos where I need to burn fat for 7 or 8 or 24 hours. If I'm doing low volume, I'm looking for CV adaptations.
