Number two is, I think, the most important thing, period! I can ride and ride and ride (like 200 miles a week) and GAIN weight if I do not watch what I eat and track and eat responsibly.
number 1 is key too or you will NOT like riding. I think this is the case for the majority of people really.
I also think and HRM is important. As I am learning, if you stay below your red line number, you can ride and ride and ride. It is a neat thing!
number 9 and 10... heck yes. Where is the like button????
Number 8 is not always that easy. Even if you exercise more then what you eat, it does not mean you will lose weight. Not always that easy.
You are on the right track my friend. Keep up the great work.
