Ok, so I'm on day 3 of my fat adaptation process. I'm almost zero carb and I'm going to be under 50 carbs/day for the next 3-4 weeks to jump start the process.

My question is on exercise. I realize that I need to go long and slow and stay in my aerobic zone, but should I be exercising at all during this 3-4 week transformation process? My goal is to be a fat adapted endurance athlete within a few months. Do I need a heart rate monitor? Should I ride my bike fasted to help with the process?
