Try this simple seated forward bend to relieve muscle tightness, increased heart rate and stomach upset. This stretch activates a sustaining energy that calms the nervous system, gets organs fully functional and clears up obstructions in the adrenal glands and kidneys.  It also calms the mind, relieves stress, stretches the spine, shoulders, hamstrings, and back while reducing fatigue.

Sit with legs extended in front of you and toes pointing up. Press the back of your legs into the floor and inhale deeply. With your spine straight and shoulders back, pull abdomens in towards the spine, and while exhaling, lean forward bending from the hip.

Fold forward as far as you can without inducing pain (keep knees bent if that is easier). With each inhalation, lift and lengthen the torso trying not to crunch, while maintaining length through the spine. Hold for a few breaths, opening your body up. Direct your breath towards the kidneys and breath deep into the lower back. Inhale and sit up slowly, lifting your torso away from the thighs until your back is straight. Repeat this exercise 2 or 3 times for a rejuvenating energy boost.
