There's a few odd pieces to the 5X that I believe needs to be fixed.
1. For guided workouts: During the workout, between sets, it should show you the upcoming exercise instead of the one you just finished. This will allow you to prepare for the next exercise or rep.
2. For guided workouts: When editing reps and weight when the 5X doesn't auto-recognize correctly, it only allows you to modify weight in Kilograms. I'm in the US. and Kilograms mean nothing to me. Don't make me do math during a hard workout. The workout in the app and on the website has the weights set appropriately - they just aren't configured for my locale correctly on the watch.
