So when Garrett’s girlfriend, Whitney Hammond, told him she was pregnant, he knew he had to make a change. Garrett, then 26, weighed 335 pounds. Like many members of his family, he had high blood pressure, but he refused to take medication. One time at work, his heart started beating so fast he could see it moving up and down through his shirt. Hammond rushed him to the doctor, who warned that he was dangerously close to having a heart attack. “It was the scariest thing in my life,” Garrett says. That experience, combined with the arrival of baby London, on March 5, 2011, finally inspired him to get fit.
