Cool Your Body Down After a Run With These 3 Trainer-Approved Stretches

Rebecca calls this a half-kneeling hip opener. "Essentially, you'd be down on one knee with the other foot in front of you in a half-kneeling position, and you'd tuck your pelvis under, pushing that hip forward to get a huge hip opener." It's also great for the quads, too, she said.

• Start off on both knees. Place your right foot forward with your left knee still on the ground. Keep your hands on your right knee.
• Take a few moments to find balance and push your hips forward to feel the stretch in your left quad and hip.
• Rebecca says to hold this for 30 to 90 seconds. Come back to kneeling on both knees, then switch sides with your left foot forward.
