As a bonus to my exercise, even though I am hovering around a certain weight right now, I have gained more strength or stamina.  In terms of riding my bike, the last couple of days on my bike ride home, towing my boys which is a combined 80lbs (give or take), I can pedal longer without feeling so winded.  Don't get me wrong, I am still Very winded and sweaty when I get back but I am happy that it is becoming a little better.
