@good_guy , you might not realize this, but you are extremely blessed, and I mean extremely, because you have zero body fat. For you, all you really need is for an ass-kicking trainer to show you how to have intense workouts and get on a high protein diet for the immense muscle growth and body change you will see. Within a month, you will definitely love the change in both your new muscle body as well as your newly found crazy libido. Then you'll become a gym rat and wonder why you didn't start doing this sooner.
