Do humping exercises actually work?

This workout wants to “hump … you up!”

A Chinese man was mocked Monday after a video of him doing pelvic thrusts in the gym — while attached to a contraption — went viral.

And just last week, a clip of pro golfer Justin Thomas sweating in a similarly erotic motion circulated on Twitter.

So is this suggestive movement a real exercise, or simply glorified sexercise?

According to Kirk Adams, director of fitness at Golf & Body NYC, it’s an advanced version of a classic gym-rat move.

“It’s basically an explosive version of the squat. It’s a belt squat,” Adams tells The Post.

The workout targets glutes, quads, hamstrings and other lower-body muscles.

“Most people, when they squat, they put a bar on their back. Instead of being loaded up with a bar on your back, you put on this belt, and the machine works on air resistance. There’s no recoil when you jump like that.”

And for golfers like Thomas, 25, this workout can help his game by increasing how fast he can swing the club and how far he can drive the ball.

Adams says the move is comparable to a box jump, but the contraption isn’t exactly commonplace in gyms yet — and isn’t for beginners.

Though he’s not ruling out that the air hump will become a trend.

“What inevitably happens is that amateurs see pros doing certain exercises and they try to mimic them, so I am sure I will be getting some questions about this,” says Adams.

As for the guy in China, Adams calls the video “a bit goofy. He is doing the same thing but in a stranger way.”

Don Saladino, owner of gym Drive 495 in Soho, says there is no scientific proof that humping is better than standard movements.

“I feel there are way better decisions [you could make] on exercise selections. Some of the best glutes in the world have been developed by some of the most basic movements,” says Saladino. He adds, “A movement like this all comes down to what I like to call ‘the entertainment effect.’”
