hey justduckie,
20 pounds is a ton o'weight to try and shed. i'm wondering how you came up with your weight goal.
since you are muscular and in excellent cardio condition your weight actually represents a powerful engine that will motor you up those climbs!
if you don't want to get bigger you can try altering your weight lifting to go to lighter weights and more reps. i think that tends to tone muscles rather than build muscle mass.
