Happy baby pose increases vitality and releases neck strain and tightness. This pose helps lengthen and realign the spine as well as strengthens the arms and shoulders. As a gently stretching pose, it is recommended to practice it at the beginning or end of a yoga practice.
If it is not easy to hold the feet with the hands, beginners can hold each foot with a yoga strap that's looped around the arch of the foot. Some practitioners prefer to hook the big toes with the index and middle fingers of each hand. It's also acceptable to hold the inside of the foot instead of the outside.
Those with serious neck injuries, recent surgery or herniated disks should avoid practicing this pose. Also, pregnant women should be very careful in this pose.
