I met with the trainer and he had me doing all sorts of stuff. We started off with planks and slowly worked my back, chest, glutes, triceps and biceps. It was a pretty thorough workout. And I knew this because the next day I woke up and I could barely walk.
Seriously - I used muscles that I never had before. I think that just because I run - I should be in spectacular shape. However, this workout proved me wrong.
So my goal is to do these exercises once a week as a weight training session. Hopefully this will help me train my body in new ways for the marathon.
