Lift legs together and pull them into your chest. Pause and slowly lower legs. Keep back straight and your head high. If this movement is too difficult or you feel strain in your lower back, try raising one leg at a time or don't raise your legs so high. Again do as many of these as you can.
Women tend to store unwanted stress in their necks and shoulders.
To release stress do shoulder shrugs. Raise your shoulders as close to your ears as you can. Keep your arms and hands relaxed at your side. Hold the shrug for up to 10 or 20 seconds. Release and take a deep breath.
