"He brought his trophy, which was nice, but we also had a two-hour session the next day," said Roskopf at the end last month in a telephone interview. Bryson said, "I want to get everything I can out of my body for the Masters."
Roskopf, a 57-year-old former strength and conditioning trainer at Fresno State, near where DeChambeau grew up, spent many years as a performance and injury prevention expert on the staff of the NFL's Denver Broncos and the NBA & # 39; s Utah Jazz. About seven years ago, Mike Schy, who coached teenage DeChambeau and played Fresno State, sent DeChambeau to Roskopf because DeChambeau had some lower back pain.
It was in Roskopf's gym-like lab in Englewood, Colo., That DeChambeau – who studied physics at Southern Methodist University and whose nickname among his colleagues is "The Mad Scientist" – found himself last. years began to transform into the tallest and most effective driver of the ball on the PGA Tour.
Roskopf put DeChambeau through what he calls a neuromuscular revision, a program he describes as muscle activation techniques designed to correct imbalances in the body that prevent range of motion, among other things. The system also aims to build higher tolerance levels for exercises that can increase strength.
When he does not visit Roskopf every three weeks, DeChambeau trains daily at his home in Dallas, where he keeps every piece of Roskopf & # 39; s specialized equipment in his garage. DeChambeau shuns many traditional weightlifting exercises like squats or deadlifts to instead focus on isolated muscle groups that control side bend, back extension, and trunk and leg flexion.
He also began consuming 5,000 to 6,000 calories a day, aided by drinking seven protein shakes made by Orgain, one of his many sponsors.
