Exercise of the Week: Side Plank with Quad Stretch | Men's Health

Exercise of the Week: Side Plank with Quad Stretch | Men's Health: "
Make your side  plank do double duty by adding a quad stretch. "You'll not only work every muscle in your core, but you'll loosen your hip flexors, a group of muscles on the front of your hips that allow you to bring your legs toward your chest," says BJ Gaddour, C.S.C.S., creator of Men's Health StreamFIT, and the mastermind behind the side plank with quad stretch."
