I figured I would give an update after training with this model for the past month and a half, and hoping that there are others who will do the same...

All but 3 rides (the only ones outside so far this year), have been in zone 2. For me that means 125-135 bpm. I have not worried about power/watts when riding.

My results -- On the trainer, I am now 2 gears higher at the same cadence at the same heart rate 125-135 bpm. My resting heart rate has dropped. My exercising heart rate drops much quicker than it used to when I slow down. My speed has increased on the trainer and outside, at the same heart rate. On my fast group ride that I have been doing for 2 years, I am on the front, with the fastest group that always pulls ahead of the rest. I used to be there, but now it is much easier. I have lost 6 pounds while eating breakfast twice, lunch twice and snacking before and after dinner. I have also found that riding indoors at 135bpm is much more of a workout than outside at the same heartrate, (not sure why that is?) maybe lack of airflow??

Anyway, wondering if anyone else has stuck to this training style and if so what are you finding? Expect that my lactate response will be greatly changed the next time I get tested.
