Motivation for Hard Intervals?

[Pedal Wench]

It's complicated to explain, but it's all pretty self-explanatory when you do it. I really like that feature on my Garmin.

Thank you!!!

When I'm on the trainer, I just write down what number interval I'm up to on the paper with my workout on it. If I forget to write down a slash mark or I'm unsure where I am, I start over.
