I have always had a Vivoactive before, but this is something else. So many possibilities, so many functions and so much feedback. Recovery advice, feedback on training load, body battery. You almost feel like a Tamagotchi where you want to keep all the meters correct. Only you are the animal yourself. You want to make sure that you sleep well, that you train enough, both in high and low zones and that you do not do too much. The suggested workouts from Garmin are very useful for this and an indication of your recovery time is also very good for this. If you follow the feedback from this watch, you hardly need a training schedule anymore. Super handy for the ambitious athlete
