My workouts are going well. Except with all the jogging, the muscles in my legs are bulking up. I don’t like it. So much so that I’m considering changing my routine. Running a 5K may not be for me.

Maybe I’m doing something wrong. I have thought about cutting even more fat out of my diet. However, I have a protein bar before a workout and I’m still wiped out before the end of the workout.

What is the best way to maintain lean muscle?
