College Weight Loss 30 lbs

When I went to college I was about 164 and in pretty good shape. Stress got the best of me and I gained about 25 lbs my sophomore year. now I'm back down and at my lightest weight ever at 158lbs. I'm looking to lose another 20 lbs. I've been running and I was able to run my first half marathon in November. I'm integrating a lot more weight training along with my cardio and I've been seeing better results. Its just 30 lbs but I tried to pick up a 30 lb weight the other day. Its amazing that I was carrying that big thing around with me! (ps ignore the persons hand on my butt)
