What does March Madness mean? That we’ve got basketball on the brain. Sure, the college guys may get a lot of attention this time of year, but we were pretty excited that we scored a chance to chat with WNBA star forward Swin Cash. Specifically, we were hoping for a little insight on how she earns the stunning feminine-meets-athletic figure hidden under her Chicago Sky jersey.Cash says she stays limber and strong with a serious regimen that combines weights, cardio, and flexibility training like Pilates and yoga. But one of her all-time favorite moves goes all the way back to her University of Connecticut days: The classic Wall Sit, that genius do-anywhere exercise that works your quads, glutes and core.MORE FROM SELF: Print Out Your March Madness Bracket!

“In college, we’d compete to be the last woman standing,” says Cash. “Your knees will turn to jelly and you’ll eventually break, but it’s really more of a mental challenge.” And we’ll be the first to agree she isn’t one to throw in the towel early–then or now. “I’m always part of the ‘last women standing’ crew. We don’t break!”Wall SitLean up against a wall with your feet shoulder-width apart. Slide down the wall so your legs are bent at a 90-degree angle. Got knee problems? Come up a bit higher against the wall to take pressure off those joints. If you’re a beginner, start off by holding for 15 seconds. Take a 15 second break. Repeat 4 times. For a more challenging iteration, hold for 30 second sets and work your way up until you can do 60 seconds at a time.MORE FROM SELF: More Celebrity Fitness Moves
