Months after picking up his first NBA championship and Finals MVP, Jaylen Brown is back to work — in the pool.

The Boston Celtics guard posted pictures of him working out underwater in a pool on Sunday. His caption on X read: “Take this pic before I drown.”

In one of the photos, Brown is standing on the base of the pool while dribbling a basketball with his left hand and holding a 40-pound dumbbell with his other. In another, Brown is doing a handstand with two dumbbells.

The workout caught the attention of former Celtic Kevin Garnett, who posted his reaction on X, proclaiming it was “over for everybody.”

Brown was named NBA Finals MVP after averaging a career-high 23.9 points in the playoffs en route to Boston’s 18th NBA title. He became the first player to win the award without making an All-NBA team since Andre Iguodala in 2015, according to ESPN Stats & Information.
