Just wanted to throw out a shameless plug for my trainer, Jodie. I've been training with her now for over 3 years - I started just before we got married. And now she is kicking my arse post baby. She is seriously great - she always keeps things challenging and changes stuff up constantly. You will never be bored.
She trains at Hi-Fi gym near Chicago and Larrabee. If you email her (findyourpeak@yahoo.com), just tell her that Megan sent ya!
