No soda's (atleast non diet ones because it isnt the carbonation that is bad it is the ungodly amount of sugar) Cut out fast foods. Me an Shanton are doing a high carb diet for a month than, cutting down to bar none next month in gear for SB, Me and him will post a thread in a month with pictures and results from week to week.
My advice is Planet Fitness. It's $10 a month and thye don't make you sign some long ass contract.

It's not hard to get in the gym just look in the mirror everyday and think about how fucked up you look and go. (That's what I do)
