For much of the last week I had been busier than usual, and had not had time to go on long aerobic walks. I DID get my minimum steps in, going to stores, running errands, and even marching in place while washing dishes. But this was not the “wind in your face” swift walking of aerobic exercise. I missed it. I found that without the aerobics, I was much hungrier in the mornings, and was in a low mood. It has been shown that exercise causes a feeling of well-being. I believe it!
