I love the saying- Passion is Pain Focused.  When you are pursuing anything worth while you more than likely experience discomfort that you have to push past.  When exercising, think about your mental limitations and how you can conquer them. I’ve always admired IronMan triathletes because they are the definition of pushing through the physical pain of a 2.4 mile swim, 112 mile bike ride and 26.2 mile run (a marathon) to reach the goal of crossing the finish line.  The training that they go through is intense and it is their passion for the sport that gives them the mental endurance to work hard.  So the next time you challenge yourself with a workout, think about how strong you are mentally and how passionate you are about being healthy!
