Back pain management with stretching routine

Main cause of back pain might be tight muscles. We sit and work at our desks day long and do not move enough. This causes the muscles to get tight which means aching muscles, including tight back with pain. For people with a limited range of motion in their back, a tight piriformis muscle is found responsible. The muscles in your buttocks and hips are very important in maintaining good posture, so keeping these muscles loose and flexible supports a healthy spine. Following stretching movements are the answer to these problems. Regular stretching routing can be extremely effective to relieve back and related muscle problems.
Back pain management with stretching routine:

1. Lie on your back on a flat surface and draw both knees up to your chin. At the same time, flex your head forward and hold this position for 20 seconds. Relax and feel the stretch along your spine. 
2. Another good back stretch for improving mobility around your spine is to lay on a flat surface with your heels flat on the floor and your knees bent. Pull one leg up to your chest by grabbing your leg behind your knee with both hands. Repeat the same stretch on the other side. 
3. The piriformis muscle runs through your buttocks area and supports the lower part of your torso. To stretch the piriformis muscle, lie on your back and cross your legs. Gently pull the bottom leg up toward your chest and hold the stretch for several seconds. Re-cross your legs and repeat. 
4. Assume a standing lunge position with your right leg forward and the knee bent. With your weight on your left hip, keep your left leg straight and gently bend forward until you feel a stretch in the hip area. Hold for several seconds, then switch to the other leg.
