Miley Cyrus and Liam Hemsworth are totally sweating for the wedding! The engaged couple is working out like fiends for their upcoming nuptials, set to take place in Australia this fall.

An insider revealed to OK! exclusively, “They’re up at the crack of dawn and on the treadmill before 7AM every day, without fail. Then it’s onto the weights and another round of cardio, squats and bicycle exercises throughout the day, as well as yoga and Pilates several times a week.”

“They’ve each got a personal trainer but do a lot of workouts in between together, which they find really helps them stick to a routine,” the source dished out. “A personal chef organizes their diet each day, and Miley’s making smoothies for them to carry around instead of calorific energy bars or peanut butter.”
