I have no idea which side of my brain I work out of. I love words, speak Spanish easily, and must have a visual in my head before I can do anything properly. Today, when riding, I caught a glimpse of my shadow, and my back didn't look straight. I thought, "I need to see someone riding with a good straight back, then I could imitate it." I recently read an article on good running form, but what really helped me was the picture of Deeva Kastor's elbows going far back with every stride. And the paragraph that pointed out why that helps. So. There you have it. Both sides of brain engaged!
