When Jonah Williams was about 12, he began building a weight room in his parents' basement in suburban Atlanta.
The tall preteen was all elbows and kneecaps back then. He thought he was too skinny, and rather than wait for nature to run its course, he decided to escalate the process.
Katherine, his mother, said he would "eat and eat and eat." And before long, her quiet, introspective son had morphed into someone different. He was born big -- just shy of 11 pounds and 22 inches long -- but suddenly he was growing in leaps and bounds into the 6-foot-5, 290-pound behemoth he'd become.
