So for one reason or another, I've been off my bike for the last 3 weeks. At this point, you might be saying to yourself, "It doesn't take long to lose your bike fitness. I should know, I read it on BF." I read BF too, so to keep in shape, I hit the treadmill until my lungs burned, my legs felt like jello, and my head spun. However, five minutes didn't feel like much of a workout so I kept at it for at least 30 mins a day, 4-5 days a week.
Today, I rode my bike for a quick errand. I knew I was in trouble right off the bat when I was flying towards my destination seemingly with ease. My mind immediately said, "Tailwind. You'll pay on the way home." Sure enough, my lungs were burning, I was huffing and puffing, and parts of my legs were protesting on the way home.
The moral of the story? Exercising on a treadmill is pointless.
