By now, you get it — rest days are important, but moving around a bit is a good thing. Today in our Just Press Play workout plan [1], we suggest a little light cardio to get your blood moving, followed by a bit of stretching. You worked your abs hard yesterday, and the front of your hips might be tight. Stretch that area effectively by adding a twist to your typical runner's lunge.

• Start in a deep lunge with your right foot forward, with your hands on either side of your right foot, and your left knee on the floor. If this is enough of a stretch for you, stay here.
• To increase the stretch, reach through your left heel, straightening your left knee to bring it off the floor. Put all your weight into your left hand, and twist through your torso, bringing your right arm to the ceiling.
• Hold this position for 30 seconds, then switch sides.
