Even the First Lady is a fan of Sasha Fierce.
Michelle Obama has been working tirelessly to encourage the nation to exercise as part of her "Let's Move" campaign, and in a recent YouTube video, the fit 47-year-old revealed she relies on Beyonce's top tunes to keep her focused in the gym.
"I always love Beyonce, so anything fast-paced that she's doing is a good one for me," Michelle said. "But I have very eclectic tastes, so my playlist on my iPod, which I listen to, runs from fast paced to a little more mellow."
Michelle has been longtime fan of the pregnant pop star, who performed at her husband Barack's presidential inauguration in January 2009.
Though Michelle finds inspiration from Beyonce's biggest hits, the First Lady encouraged the country to "listen to whatever you like and whatever is going to get you motivated."
"The important thing is that you get up and you try to get that workout in," she said.
