Downward Dog
Start on your hands and knees. Walk your hands and feet out and raise your hips. Keep walking out until your arms are straight and in line with your neck. Your legs should also be straight, but if you have tight hamstrings you may have to keep a slight bend in your knees.
Push the ground away through your palms and push your heels toward the ground. Hold this position for 5-8 breaths and repeat three times.
Triangle Pose
Start by standing with your arms extended to your sides. Stand with your feet about three feet apart. Turn your right foot out 90 degrees and turn your left foot 45 degrees. Walk your right hand down your right leg by bending your trunk and keeping your arms straight.
Look at the ceiling and hold for 5 breaths. Repeat each side twice.
Cobra
Lie face down on a yoga mat with your hands in a push-up position and the tops of your feet flat against the floor. Tuck your hips downward and squeeze your glutes. Press your shoulders down as you push the ground away and lift your upper body from the mat. Hold for ten breaths and repeat three times.
Child’s Pose
Start on your hands and knees and bring your knees and feet together. Sit back on your heels and stretch your arms over your head while keeping your hands on the ground. Touch your forehead to the ground and relax your entire body. Hold for at least a minute. Repeat twice per day.
