I found this site last week and decided that I would put it to good use. Today was my first day and I was able to perform all of the beginner home exercises. I feel it too! But I will not be deterred...it is a good burn. I'm making a commitment to myself to keep this up(5 days a week) for at least 90 days. I know it takes 21 to make something a habit but I want this to become ingrained in my spirit. As my body adjusts I will increase the intensity. Hopefully I will learn to love exercising. My health depends on it.
