Personal Trainer: I am committed to you. I am passionate about your health and fitness goals and delighted to coach you and hold you accountable to your success! Accountability to a personal trainer is a great way to lose weight and get in shape, because I am going to hold you to it! Accountability though, I realize, can be easy to rationalize away. Not accountability to a spouse, partner or friend. They'll stop nagging you because they don't want to damage the relationship. The secret is accountability to a professional. A mentor and guide.someone who is committed to your commitment and impervious to your excuses.
