In addition to the weight loss, Rodgers added more yoga to his offseason routine.
"A lot of flexibility's helping with those injuries as you get older," said Rodgers, who turned 30 in December.
Rodgers said the collarbone injury -- suffered in a Nov. 4 loss to the Chicago Bears -- also played a role in his different approach to the offseason.
"I just had to rest and get into my routine when I did," he told reporters. "There were some things I shied away from -- some heavy lifting, especially shoulder stuff in the offseason -- but I did my rehab and took it slow and feel good."
