Stand at ease on the yoga mat, keeping your legs apart. Place the foam brick in front of the left foot. Bend your torso and try to touch your toes with your fingers. Now hold the foam brick using your left hand and take your right arms up in straight line, parallel to the walls. Resting on the brick, swing your right leg parallel to the ground. Maintain the position and resume your initial position slowly. Repeat on the other side. This pose is 3rd version of Warrior pose. It stretches and strengthens the spine, legs, and shoulders. 

Avoid this pose during cardiac issues and blood pressure.
