There's no better way to show off your progress than creating a "before/after" photoalbum! You can create just this on your personal profile.
On the main page of your profile, you see a tab called "progress pictures". Here, you can upload pictures of your progress. If you're training with a coach, you could ask him to take pictures of you to track and publish your hard work.
Of course we understand you might not want to publish these pictures for the whole world to see, so make sure your privacy settings are set how you want them.
