Raheem Mostert is preparing for a bigger role as his San Francisco 49ers look to defend their NFC title.

In an interview this week with Eric Branch of the San Francisco Chronicle, the Niners running back said that he was bulking up in anticipation of a larger workload for next season.

“I’m actually gaining some more muscle, which is kind of bizarre,” Mostert said. “I’m just trying to incorporate those things in my daily workouts so I’m able to take those hits and be one of those guys that are getting 200 carries. I’ve got to get prepared for that. And the only way I know how is to get bulky and stronger.
