No I am not certified yet. I am just working with what I know right now and training as I go along.
After I lost my "bomb" weight I lost another 15 when I started running to relieve stress. So I recommend it highly. I actualy have muscle definition on my arms and not just blobs anymore. I hated running when I was young because my lungs hurt so much. But it turned out I had asthma. Now that I am on meds for asthma, running is no big deal.
