How to perform downward facing dog in yoga
Stand in tadasana.
Start by standing in tadasana, or mountain pose, at the front of a yoga mat. This will allow you to most easily flow into downward facing dog from a standing position.

1). To begin this pose, stand with your feet shoulder-width apart. In tadasana, the feet are pointed over your head, an appropriate distance from each other.
2). If you're experiencing more space in your yoga studios, you may need to increase your form. Tadasana is generally done in the middle of mountain pose, though you may want to sit down and even get into downward facing dog to deepen your breathing.
3). In tadasana, or mountain pose, you stand at the front of a yoga mat with your feet together and your arms at your sides. Gaze forward, spread your toes, and make sure your balance is evenly distributed between both feet.
4). If you're male, you will be most likely to be left unsupported by the mat, and your good posture can help enable you to feel as balanced as possible in this pose. If you're female, you will want to be slightly outside of tadasana as you try to flow into downward facing dog.
The answer is:
3).
