Um, what is that man doing to that weight machine?

The gym is a great place to snap discreet selfies in the mirror, walk around naked, and check out other people. It can also occasionally be a good place to exercise.

And for some, it’s a place to hone their topping skills.

Video of a man who appears to be topping a leg curl machine recently surfaced online. Our friends over at Gayety first shared the video on their Facebook page.

Since being uploaded last week, the video has received nearly 100,000 views and over 550 comments.

“OMG, he’s clearly not a top,” one person wrote.

“He’s using the equipment to masturbate,” another person adds.

“His thrust is slow and sensual,” a third person observes.

Practice makes perfect, right?

Watch.
