Below are few Yoga poses to increase energy and reduce fatigue. Practicing yoga increases your energy, power, strength and endurance, whilst strengthening weak or under-activated areas of the body.
Twisted Chair Pose: 
Twisted Chair pose helps increase circulation by not only using every muscle in your body but also twisting, which wakes up your internal organs and aids in digestion. Stand with your feet and legs together. Make an action as you are sitting in a chair far behind by bending your knees and sinking your hips down at a time. Palms should be placed in front of chest. Your right elbow is moved until it reaches your left knee by rotating the spine simultaneously. Chest should remain lifted all the time. You should be able to hold it for 30-45 seconds and try the same on the other side.
Bow Pose: 
Bow pose strengthens the back muscles and stretches the front part of your body. Lie down on the mat in prone position, hands placed alongside your body, legs stretched out to the back. Your ankles should be grabbed with your hands by bending the knees remaining in same position. Now lift your heels up and away from your body, keeping your legs hip-distance apart, which pulls your chest up off the floor. Shoulder blades should be kept down away from the ears all the time. You should hold this for 30-45 seconds, while releasing head should be turned to one side. Repeating this for two or three times shows best results.
Bridge Pose: 
Lie flat on your yoga mat, with your feet flat on the floor. Now exhale and push up and off the floor with your feet. Raise your body up such that your neck and head are flat on the mat and the rest of your body is in the air. Try doing this 5-10 times and then release. This is effective yoga pose to improve immune system.
Shoulder Stand: 
Shoulder stand gives great stretch to your upper back and neck. It also helps in the good circulation of adrenal, thyroid and pituitary glands. Come onto the floor, lying on your back, and bring your feet toward your bottom. Bring your hands to your sides back, and push on the floor with your arms to bring your feet up into the air. Place your hands on your lower back for support and focus on keeping your legs straight and your shoulder blades pulled together. Gaze at your belly button and breathe here for 30 seconds, before slowly rolling out of the posture, placing your spine onto the floor one vertebra at a time until you’re lying on your back once again.
Fish Pose: 
To come into fish pose, remain on your back and bring your hands under your bottom, with your palms on the floor. Elbows are bent and by pressing weight into them you should lean on them. Your back should be arched as you lift your chest up towards the ceiling. As in the bridge stand, elbows are brought towards each other dropping the head back behind your body.
