What gets you motivated?

The hubby and I decided to start a gym routine together to help us both get in tip top shape for TTC and help me stop obsessing over it all!  I feel great since we started a few days ago  which keeps me coming back but I had to work to get motivated initially.  To make myself feel good about working out I bought a new pair of running shoes and 2 pretty sports bras ? Whatever works right?!  What gets you motivated to get moving?
