im 16 and have been working out for like 6 months or so. i started running then did a little biking. but now i run all the time. and i recently joined a gym about a month ago. but i want to know more about fitness and expand my knowledge on diet and exercise. im asking because i not only want to know more on fitness, but being a fitness trainer seems like a good job when im older if im really interested.
any suggestions?
