|That dapper dog Pitbull seen here|
For me, it is a combination of both music and images When I am at the gym, I keep my Pandora on either Pitbull Radio or DMX Radio (thanks Rach for the tip). I also like when the TV's at the gym are showing E! I know that attaining a celebrity body isn't realistic nor most likely healthy but it does make me increase the speed of the treadmill.
Can you conjurer up an image that makes you push harder those last 5 minutes? Or is all about the music? What about the scale? Is it all about the weight?
