Even though Beyonce has chart-topping records and has received countless awards, she actually still gets nervous before a performance, and is sometimes self-conscious about how she looks on stage.

In order to get ready for each grueling performance, she prepares for weeks, both physically and mentally. How does she do it?

Be Realistic

She has the right outlook. Beyonce knows that there isn't a quick fix when it comes to a healthy lifestyle. "The truth is, it's a lot of sacrifice. It's more about your mental strength than physical strength. You have to push yourself. It doesn't matter what trainer you have. And it doesn't matter what program you're on. You have to be healthy and make the right choices," she says.

Be Time Conscious

Beyonce is a fan of celebrity trainer Marco Borges, who trains her using his signature Power Moves philosophy. This system helps Beyonce save time since it relies on exercises that work several muscle groups at once. She also saves time by interval training, alternating between sprinting and running while on the treadmill, to burn more calories in a shorter amount of time.

Be Opportunistic

Being an opportunist isn't always a bad thing.  Although she may be busy, Beyoncé knows when she can fit in a few extra calorie-burning moves, like squats, lunges, and planks, no matter where she is.

Be Your Own Motivator

Whether it's a picture of an Oscar by her treadmill or a dress she wants to fit into, Beyonce always has a way to motivate herself to work out. And it's no surprise that the singer uses music as one of her main workout motivations.
