From the pages of Vogue to rolling with Jay Z's entourage, Skylar Diggins is not only a star on the court, she's a rockstar in the gym. We caught up with the WNBA star to talk about her killer arm workout. Skylar says to start out you don't even need a gym...just find a household item you can curl, like rocks or a milk jug! She says the most important part is to make sure you are engaging your core! Suprisingly, its all about the reps you do, not the weight- and the more reps you do controlling the weight, the better results you will see! While Skylar has the secret to toned arms, she also makes sure to stick to a healthy diet, and that includes getting in chocolate milk after a workout! She also loves to treat herself to smoothies!.
