When WNBA star Skylar Diggins steps off the court, she's hanging with her friend Jay Z, rocking the red carpet and gracing the pages of some pretty impressive mags, but we had to ask just how she gets those killer abs! Tune in to watch Skylar teach CelebTV's Kelli Zink her workout routine-- starting with holding the plank! To kick it up a notch Skylar says to switch to a low plank, and from there to transition from the high to the low. She says the most important thing is to not have any movement in your hips during the transitions. As for the diet? Skylar says clean eating is super important and her go-to snack is almonds and greek yogurt! Check out the workout and more, here!
