I know that exercise improves my overall well-being.
Running helps me problem solve. It also boosts my mood when I'm feeling less than chipper.
Swimming, though it's not my favorite, destresses me. Perhaps it's the calming effect of the water, but when I get in the pool, I feel like the weight of my life is lifted from me.
Biking gives me a sense of accomplishment. With what other sport can you tell people, "I did 50 miles today"?
Yet another reason why exercise and triathlon are such a big part of my life.
