The Miami Heat after-party may only just winding down for some, but superstar forward LeBron James is already in offseason workouts.

The four-time MVP has posted three clips on Instagram showing him in full practice mode.

He's working on his three-point shot, post up game and mid-range jumper - his key shot in the title-clinching Game 7 against the San Antonio Spurs last month.

James is a notorious workout fiend, and it's no surprise to see him back working on his game already.

After back-to-back NBA Championships, he'll be targeting a third consecutive title with the Heat.

After next season? Who knows. James will be free to test free agency if he wanted to, although it would be a surprise to some to see him bail on the Heat.

Anyway that's for another time. Check out the clips of LeBron in offseason action here...
