Adele has revealed she's "working out like an athlete" so she can be fit enough to walk around the stage in Germany.
The Hello singer has been training three times a day in order to prepare for her series of shows in Munich this coming August.
"The reason that I am working out like I'm an athlete again is because those shows that I announced in Germany, that stage is f**king enormous," she admitted, according to MailOnline. "I'm probably going to walk about eight miles (12km) a night, so I need my cardio and my stamina to be up."
The 35-year-old has a strict routine she's adhering to, although some of her training methods are certainly unusual.
"I have upped my cardio game at the gym. And I might start doing what Beyoncé had to do when she was a teenager. They used to make her do a run around a park or a treadmill with high heels singing. So I might start doing that to really open those lungs, although I don't wear my heels. So I'll just wear my trainers."
The star will finish her residency in Vegas in June, before performing 10 shows in Munich in August.
"I am back at my gym grind like nobody's business," she said. "My a**e is getting rock solid again. I can move mountains with my bum."
