Stupid Heavy Muscles.
Going to the gym the past couple of months has been frustrating. After the first 4 months, I really didn't see any results. I had been doing the personal trainer's recommended routine (from a free 1 hour starter session) on the FreeMotion machines; followed by some time on the elliptical machine.
But I just wasn't seeing any results - no pounds off the scale, no looser pants. I wasn't expecting something dramatic, but I was expecting something.
It turns out I was building some muscles - stupid heavy muscles. I noticed that I had a much easier time hiking in August. And I'm never winded when walking up the hills in downtown Seattle anymore. (Hey - those hills are steep.)
