Green Day did close to three hour shows on their Saviors tour last year, and Billie Joe Armstrong said it's something he definitely couldn't have done a couple decades ago.
Armstrong told Kerrang, "I try to take really good care of myself -- which is a lot better than the days I didn’t take care of myself. I love going for long runs, which is good for my mental health. I like to work out, and I swim a lot. I think that puts me at ease, but I also think it contributes to my voice, which is the one thing I don’t ever want to lose. I try to take really good care of that at this stage of my life -- keeping my chops up."
Armstrong adds that keeping his chops up is why fans see him do so much outside the band. “And that’s why I do so many side-projects, honestly! When it comes to doing The Coverups, it’s a chance for me to just jam with my friends and then go play a show -- it keeps me in vocal shape, you know? They’re really fun club shows, but they also serve a really good purpose.”
