It’s not all hard work on the Biggest Loser Ranch. There’s also twerking, rapping and a whole lot of laughs happening there.

In a new bloopers reel released today, the cast of ‘The Biggest Loser’ is shown in some of their not-so-camera-ready moments. From Dolvett Quince showing off his rapping and singing skills (he’s pretty smooth, eh?) to Bob Harper attempting to get his ‘Miley on’ by twerking around the gym, the reel is full of funny moments.

Watch the video to see what really happens behind the scenes of ‘The Biggest Loser!’ (Not gonna lie, I totally swooned while Dolvett was singing!)
