LeBron James has caused a social media frenzy after impressing his legion of followers with a fitness video.

The 38-year-old may be nearing the end of his career, but he is still putting in a lot of work before the start of the new NBA season next week.

James is entering his 21st season as a professional basketball player and hopes to add a fifth NBA championship to his collection.

James’ Los Angeles Lakers open the season against the Denver Nuggets, the reigning NBA champions.

And as shown in a workout video posted to Instagram by the Lakers, the Cleveland Cavaliers legend is making sure he is in tip-top shape.

James did five pull-ups in a video captioned “the work doesn’t stop,” leaving viewers in awe of his chiseled physique and work ethic.

One commenter said, “Year 21 Bron gone be athletic and quicker this year.”

Someone else put it like way: “Bro got front and back abs. All right, let’s get going!

“5th ring on the way!” exclaimed a third.

In a subsequent post, this cheerleader said, “I feel like people don’t talk about his work ethic enough.”

Furthermore, this person was complimented on their “off the chain” work ethic. Totally committed.

While everything was going on, one of his fans commented, “He built different.”

James enters the 2018 NBA season as the league’s all-time leading scorer with 38,652 points.

After Udonis Haslem’s retirement and Andre Iguodala’s departure from the Golden State Warriors, he will also be the league’s oldest active player.
