I like the current set of workouts, sure it may lack some variety, but overall its a good first run. I just wish you could setup custom workouts with your own intervals or stages.
MS Band can only save one workout schedule at a time. Just find it is a little bit pain to use the workouts with several different schedules in a week. Has to download and update schedules everyday. It will be ideally to download and save the whole set of schedules in MS Band. Every time just jumps onto the next schedule.
