Miami Heat swingman Jimmy Butler is looking absolutely shredded ahead of the team's impending playoff rematch with the Milwaukee Bucks.

The Heat tweeted out an image of Butler putting in some work and, well, he basically looks like one of the Spartan warriors straight out of the 300 movie.

Playoff Jimmy has arrived, apparently. Can Butler help the Heat pull off yet another playoff upset of the favored Bucks?

Miami comes into the series with a good deal of momentum. The Heat won 12 of their final 15 games to grab the No. 6 seed in the Eastern Conference, setting up a rematch of last year's series with Milwaukee.

For his part, Butler has quietly had one of the best seasons of his career. The 31-year-old set new career-high marks in assists (7.1) and rebounds (6.9) per game while also averaging 21.5 points and leading the NBA at 2.1 steals per game.

The Heat star checks just about every advanced metric, as well. Butler finished the regular season ranked seventh in value over replacement player (VORP) and fifth in both win shares and player efficiency rating (PER). He ranked third in win shares per 48 minutes, behind only MVP favorite Nikola Jokic and Philadelphia 76ers star Joel Embiid.

The Bucks will pose a different sort of challenge this time around. The addition of Jrue Holiday could be a boon for the Bucks, and they have more shooting and shot-creators than they did on last year's roster.

However, Butler has already proven he can elevate his play in the playoffs. He looks prepared to lead his troops into battle as the Heat hope to make another deep run.
