1) Tell someone close to you your goals and set a deadline!
This will give you accountability, support, and someone to just plain bug you when you don't hold up your side of the deal!
2) Make a "contract"
Write up rules, regulations, and violations and sign it and have some one witness just like a legal document!! I know it sounds silly but trust me creating another web of accountability is very important!
3) Join a "support group"
Talking to others about where you are and just relating to others can really help keep you pepped up and motivated! Just go to www.beachbodycoach.com/bethsimpler make a free account and start chatting on the message boards!
4) Have a "challenge"
Challenge your spouse or coworkers to go in with you and have some kind of prize at the end of the time period for the person who lost the largest % of weight!
5) Sign up for something with a deadline and pay for it!
Sign up for a local 5k or a competition something with a definite date and costs money...you are less likely to throw money away and more likely to just train for it!
Those are what has worked for me so I really hope that helps you and of course I am here as an accountability/coaching resource as well!
