Accountability in San Diego

Sooo, over the last 3 years I've been doing body by XBOX, sponsored by Guiness and Pizza Hut. It's not really conducive to a healthy lifestyle. I'm really looking for some people that will keep me in check and hold me accountable for my laziness, if...okay, when it happens. I was a certified personal trainer in the past, so I know what to I need to do, but at times I lack the self-motivation. I've always been more concerned with disappointing others than myself, ergo here I am seeking some external motivators, and I'll in turn do my best to motivate you to stay on target. I'm not sure how this works, adding people, so someone may have to educate me. Thanks, and good luck in your own endeavors.
