Carrie Underwood unveiled her new fitness app, fit52, earlier this year as a response to the COVID-19 pandemic and focus on at-home workouts. The singer has been expanding her health & wellness empire and has now added her husband, former NHL star Mike Fisher, onto the roster of trainers.

Underwood made the reveal while sharing a photo of herself and Fisher sweating it out together while appearing to do push-ups ... or holding plank. The two are constantly supporting each other, and can't even avoid eye contact while in the middle of their reps.

Users of Underwood's fit52 app are already responding well to the addition of the former NHL star.

"On my girl Carrie’s path, but love getting Mike’s workout cards mixed in there!" one fan wrote.

The app allows you to follow the "path" of the trainer, and one person said Fisher is not taking it easy!

"Mikes path kills me 4 days a week. I have a love/hate relationship with it," the tired user wrote.

Another customer was more focused on the partner aspect, asking Underwood, "Welp, I don't have a partner so can I borrow yours?"
