Child's Pose is a resting posture in both Yoga and Pilates. It gives the participant an opportunity to refocus on proper breathing techniques as well as any intention that was set for the practice.
To perform, you can keep the knees together or spread while folding the torso over the thighs. It's meant to be a comfortable resting posture, so let those hips sink as low as you'd like, and extend your arms either overhead or along-side the body.
From Child's Pose you can easily stretch the neck in Rabbit Pose. Placing the crown of the head on the mat, roll the hips skyward and interlace the fingers behind the back. You can stretch the arms skyward as well or let them rest along the torso wherever comfortable. Although Rabbit is a semi-resting posture, it is important to keep the core engaged to protect the neck.
Another pose to which you can easily transition is downward dog. Honor your body and let your practice flow.
