Thanks for the tip about the split cardio/weights workouts. I should have my watch in the coming week and am looking forward to trying the Workout app in the various classes I go to, one of which is a combination of a Pump-style work out with weights and a cardio part with a step.
Have you found it fiddly to stop and start in the middle of workouts, or, once you know your way around the app can you do it fairly easily?
