We already work out with “Crazy in Love” and “Flawless” on full blast, so the logical next step is rocking apparel from Ivy Park, Beyoncé’s new activewear line. The singer follows the celebrity athleisure path blazed by Kate Hudson with Fabletics and Carrie Underwood with CALIA. But Beyoncé isn’t one to jump on the bandwagon just because something is trendy. In this two-minute ad, Beyoncé talks about how running in Houston’s Parkwood Park as a child gave her time to reflect on what was really important to her. She says those workouts also prepared her for future challenges, from performing in front of sell-out crowds togiving birth to her daughter, Blue Ivy Carter, who the clothing line is named after.
