John Travolta's son is reaching new heights!

On Tuesday, the Grease star, 68, shared an impressive new video on Instagram of his 11-year-old son Ben practicing his parkour skills at an indoor adventure gym.

Travolta noted that Ben recently achieved a new ranking in his training, becoming a "level 3 ninja."

"I'm so proud," added the actor.

Many of the actor's famous friends replied to the video, commenting on Ben's skillful moves.

"Right on Ben," Mario Lopez wrote, while Jamie Lee Curtis added, "WOWZA"

"I want to do that !🙌🙌," Debi Mazar replied.
