Do you tower over people when standing, but look normal height when sitting? Are you all arms and legs? Then you, my friend, are not only tall, but also long-limbed. Being tall is cool. It helps with most athletic pursuits, you never need worry about seeing over the crowd at a gig, you can reach stuff that others need a step for, and, in general, being tall makes you more attractive. While there are many benefits to being tall, muscle building is not one of them.
