Take a step and set your foot down like you are pressing a stamp into the soft wax to make a seal. When that foot is firmly on the ground and your weight is on it, lift the other foot and carry it forward. Then press feel how you set that foot onto the ground like you are pressing a stamp into the soft wax to make a seal. When you lift the foot you breathe in and when you set it down you breathe out. You can also set one foot with the in-breath and then carry the other foot forward and set it with the out-breath. Always keep the back foot on the ground until the front foot takes the weight fully.
