Jim Harbaugh sure knows how to make the most of his offseason.

The San Francisco 49ers head coach visited California’s Six Flags Discovery Kingdom on Sunday and got into a pushup contest…with a walrus.

As you can see in the video, Harbaugh still has peak athletic form, while the nearly 1,800-pound walrus is, well, walrus.

It’s yet another odd way for Harbaugh to spend time when he’s not roaming the sidelines. You may recall that last year he went to a taping of ‘Judge Judy,’ where, presumably, he may one day return to prove Richard Sherman is a jerk.
