Start with a forward bend.
While exhaling: lower your torso toward the floor, keeping the spine straight. Place your fingertips on the floor just outside your feet. The fingertips should be aligned with your toes. Bring the torso and head toward your legs in forward fold.Try to place your hands flat on the floor. Hold.
This pose can be used as a resting position between the poses. Stay in the pose for 3 seconds.
If it was difficult, don't worry about it. Do the Sun Salutation A from my book (below) for a month and you will see a difference.
