Bend the knees, and sit lightly between the heels. Your knees should be out wide on either side of you. Rest your forehead on the ground in front of you.
The arms can be behind you or stretched out in front of you. This is a total relaxation pose and you shouldn’t be working anything in it. Just focus on resting what feels sore. Hold for 5-6 breaths or as long as you need it before moving onto the next pose.
Child’s pose is often done at the end of practice as well to cool down or reflect on your practice.
Remember that the hardest part of a yoga practice is getting yourself on the mat every day! Your health and well-being should be the highest priority.
