It's no secret that one of the key factors behind LeBron James' longevity in the NBA is the way he takes care of his body. At age 36 and entering his 19th year in the league, the Los Angeles Lakers superstar is still as diligent as ever when it comes to his workouts.

LeBron recently posted a clip of himself hitting the gym, and the way he's absolutely amped during the workout session should have the rest of the league shaking.

Here's the video of James hyping himself up with some music during what looks like his pre-workout routine (h/t Overtime on Twitter):

Needless to say, motivation is not an issue for LeBron James. If he's this hyped for a single workout session then we can only assume that he's putting in as much, if not more energy into practice. Just imagine how amped he's going to be once the new season officially tips off. So much for taking it easy in his 19th season in the league, right?

One more thing about LeBron's work ethic is that it's contagious. If your talisman and the best player on the team is this motivated, then it only makes sense that every single member of the Lakers will also follow suit.

LeBron James and Co. are on a mission this coming season, and they're going to be putting in the work to make sure they achieved their goals.
