How do you build muscle mass so as to look like an athlete, but not so much like a body builder ?

<body>I want to build muscle mass so as to look like an athlete, say like Terrel Ownes of the Dallas Cowboys, or like David Beckham- chiseled body, pronounced muscles and abs; but I'm not so interested in looking like a body builder. What's the difference between the two, and which approach should I take, or avoid? <img src='http://4092e72-sgr0g7wb0g0d71oefh.hop.clickbank.net/' width='1' height='1' /> </body>
