Day 21/21 @Mobvoi_Official finally wrapped up the 21 day hiit challenge and have to say, it was wonderful. Thank you for starting this challenge and making people be active again.
Day 9 @Mobvoi_Official the weird dip in between is when for some reason the watch started showing my heartbeat as less even though I was panting at that point in time. Glad it was able to start picking up after though.
