I am a firm believer in and defender of the idea that exercise is a personal expression. So many people think there is a perfect way to perform it, that they avoid even getting started. They hear advice from fitness experts who have labored to find their path of exercise, their personal expression, and if it doesn't resonate with the layperson, well they don't even start.
My advice? If you find something you love--do it! Throw yourself into it. Join a club or group of enthusiasts and surround yourself with it. Buy the shoes AND the shirt. If you don't have the results you had hoped for or you injure yourself (I hope not), consider why. Learn from it. Grow.
