Fitness to me isn't one workout, it isn't training for one competition, eating healthy this month, or looking good for a trip. It's about making changes to the habits you want to improve, and trade them out for habits you want to adopt.
Try to think about what type of habits you want to make a part of your life, and after you think about them start DOING them. The only way you can change is by doing! I promise if you don't give up ad you are consistent, you will be able to change for the better.
Out one foot in front of the other and commit to change!
