After reaching the NBA Finals this season, the Boston Celtics will spend the summer recovering and preparing for another long postseason run next season. They’ve made some significant signings and will be hoping that their current players improve inside as well.

Brad Stevens has already acquired Danilo Gallinari and Malcolm Brogdon to the roster, providing the Celtics with further depth. However, if Boston wants to go the additional mile next season and bring home the Banner 18, its stars will have to do the same.

It appears that Celtics star wing Jaylen Brown has already started this process. In a video he posted to Instagram, he is seen doing a tough workout in the water with weights. The video quickly went popular on Twitter after it was shared by the Celtics’ official account.

Brown has already begun working on his body in preparation for next season, and Celtics Twitter has taken note. The star’s training routine has already piqued the interest of fans and members of the media on Twitter.

Brown’s Workout Reactions on Twitter

Several media sources shared the video, commenting on Brown’s fitness routine. Overtime, SLAM, and theScore all tweeted the video out on their feeds.

However, major media sites were not the only ones to respond to Brown’s workout. Celtics fans used the occasion to make jokes and express their excitement for the upcoming season.

Brown, according to one Twitter user, is the Aquaman to Grant Williams’ Batman.
