On Friday, McPhee, 35,shared an impressive clipof herself belting out the tune while on an elliptical machine.
“Listen to meeee gee wiiiizzzz,” McPhee captioned the clip. “I’m singing a new little secret song that David wrote for something special during my vocal exercises with @amychapman — Don’t Judge me! 😬🙏🏼”
For her musical exercise, McPhee wore a t-shirt, jean shorts and white sandals.
While she managed to hold the note throughout the clip, McPhee was visibly and understandably out of breath as she fanned herself and yelled out, “Oh Jesus.”
Nonetheless, she finished strong crooning the final lyrics.
The post prompted a number of her followers to praise her with one writing, “We can barely stand and sing, let alone do cardio AND sing!”
