If you are trying to lose weight or change your bodies composition, it's a great idea to start keeping a food journal. A food journal will help hold you accountable for what you are putting in your body. It's  a great way to track progress. If you're struggling to kick bad eating habits having to write down everything is a good way to address what foods you need to avoid. It's also a great way to track your macronutrients (protein, carbs, and fats.) these are all important factors in reaching your goal.

 Start believing in yourself! If you don't think you will accomplish your goals you're right, you won't. The body does what the mind tells it to. In order to strengthen the body you must first strengthen the mind. When you get to the gym don't just go thru the motions. Go in there with determination and give 100% into every rep, and every set. Dont settle for average. Average effort gets average results. You are capable of anything you put your mind to! If it's important you will find a way, if it's not you will find an excuse.
