When it comes to Miranda Lambert’s workout regimen, the country superstar has a leg up on hubby Blake Shelton and tour partner Dierks Bentley.

Blake surprised fans at a recent stop on Miranda and Dierks’ Locked & Reloaded Tour, and Dierks reveals he and Blake even spent some time before the show getting physical with Miranda’s personal trainer.

“Watching Blake work out is pretty hilarious,” he says. “I actually posted a Twitter picture of what a Blake Shelton workout looks like. It involves a lot of lying face down on the ground arms and legs spread out.”

He goes on to say both he and Blake are “getting [their] butts kicked” by Miranda’s trainer.

The Locked & Reloaded Tour rolls into New York and New Hampshire this weekend.
