Lift heavy things!

Here's a fun one that illustrates my point exactly.  This first photo was around August 2013 when I was my thinnest (135 lbs???) Definitely between 135-140. I look small. Looking at this I look small. This is while at the gym but still not lifting that heavy yet. And then this photo was yesterday, at about 147 pounds but clearly much more muscular. I like the 2nd picture so much more!!! Lift heavy things said the runner!
