A couple of America’s Got Talent contestants just made judges Mel B and Sofia Vergara part of the act, much to their distress.

It happened on Tuesday’s episode when two buff contestants took the stage, where they had set up a makeshift gym, not to lift heavy dumbbells but to throw them to each other.

The men, Darien Johnson and Scott Mathison, explained that they found each other through social media, where they both share their extreme workouts. They’ve since collaborated on videos that have received up to two million views.

After the former Spice Girl gave them a positive review — “that must be hard work!” — she and Vergara were invited to take the stage, without a description of what they’d be doing. The women were then instructed to stand back-to-back, after which the performers began to toss the the weights over their heads.

“If you had to lose one, which one would it be?” their fellow judge Simon Cowell joked to Howie Mandel.

Meanwhile, the women were visibly rattled by what was happening around them.

“I don’t want to be here,” Vergara protested, although she stayed in place.

Mel B insisted that Vergara “hold my hand!” She kept her eyes squeezed shut.

In all, Johnson and Mathison passed the huge barbels back and forth over their heads six times.

When it was over, the two judges hugged.

As they walked back to their seats, Vergara noted that the experience had been “so scary.”

Mel B raved: “Oh my god. What you do is proper. Fit and hot.”

It was a first for the show, Vergara thought. And she appreciated the act too: “It looks really hard. Looking at your bodies, I can tell.”

Cowell and Mandel were also fans.

“I think it’s entertaining,” Mandel said in his assessment. “It’s a strength act. It’s an agility act. It inspires people to be in shape. I think you checked a lot of boxes. I loved it.”

All four judges gave the act the go-ahead, which means they will face off against contestants doing equally dangerous acts such as roller-skating while performing aerialist stunts or throwing knives.

America’s Got Talent airs Tuesday at 8 p.m. ET/PT on NBC, with the Live Shows beginning Aug. 19.
