I've been exercising a lot more in conjunction with my weight loss efforts. Today I did 16 miles on my hybrid bike (earning 7 WW points). I also just starting using an Omron heart rate monitorOmron HR-100C Heart Rate Monitor, which seems to work very well. Now I now when I'm at an optimum level of exercise.
Three days a week I do dumbbell workouts and two days a week I do pull-ups on a pull-up bar I installed in the doorway of our laundry room. When I started out I could do one, now I can do three pull-ups from a complete hang.
