Michael Bublé may be better known for his pipes than his pecs, but both get a workout when the Grammy winner gets set to sing.
To clear out his sinuses before performing, "I do push-ups, it opens me up," says the Canadian-born singer in this exclusive video. He also admits he wears Breathe-Right strips, but laments that he looks like "such a nerd."
Bublé's fourth album, Crazy Love, hits stores Friday.
