Hi, today I have been very curious if my apple watch exercise ring is working properly. Today I have gone on two 2 mile walks (40-50 mins each), 1 20 minute walk and 1 10 minute walk, and my exercise ring is only at 24/30. I don't get it, I burned 100 calories on my second two mile walk, which was forty minutes and i only gained 6 minutes onto my exercise ring. Is something wrong? I had a friend along with me and on our first two mile walk she had filled her whole ring and a 1/4 on top of that, while i only gained half of my exercise ring.
