Once your heart rate slows down following an intense interval workout and cooldown, perform a stretching routine to give your muscles a little TLC. Try this stretch after intense cardio, such as running or other workouts that require sudden changes in direction. This move works the piriformis, a deep gluteal muscle that helps to rotate and stabilize your hips during training.
From a seated position on the floor, bend your left leg in front of you so that your knee points to the left and the sole of your foot to the right. Extend your right leg straight behind you. Keep your torso tall and hold here for five breaths, or, for a deeper stretch, reach your arms straight ahead and fold forward as shown. Gently release when you are done, then switch sides.
