Thanks for the suggestion! I'll see if I can add that in the future when we shoot some more videos--it has been on my list for a while as other members have suggested it as well. Thanks for the reminder.
If it helps, my Cardio Blast DVD (available in the SparkPeople Store) has a 10-Minute Walking Workout on it (as one of 6 different cardio workouts).
Glad you find the videos helpful. Thanks for the feedback.
