apple watch heart rate not accurate

My heart rate is not accurate on the spinning bike. And, If I run on the treadmill, it won't take heart rate at all. Now Ive discovered that if I shake my arm (the one with the watch on it) the heart rate will return to normal for a minute or two. Then come down. I shake it again and the heart rate goes back to accurate. What is up? This is a series 7 watch.
