Just thought I'd post the latest in my health and fitness accomplishments. In addition to losing nearly 30 lbs, I am now able to do unaided chin-ups! In the past, I have needed to use a fitness machine that counters some of your weight so that you can do the exercise. I was only able to do three sets of two chin-ups, but I was able to do them. Never before in my life have I been able to do unaided chin-ups. So, woo hoo!
