Due to my schedule, I will be reallywas working to make sure I can get my workouts completed in about 1 hour. It turns out that I burn the same amount of calories (I burn approximately 700 calories per workout) in 1 hour versus 1.5hrs with longer rest periods. I don't have the extra time to spend lolly-gagging anyways.
Now that I am done with class for the summer, but schedule has changed. I don't have it down to a science yet, but when I do... I will be writing another post for you.
What is your workout schedule like?
