Tools for Teaching Prenatal Yoga: The Second Trimester
Chest and hip openers are favorite poses for this trimester. The muscles of the upper back have the added weight of new breast tissue to support, so poses such as Gomukhasana (Cow Face Pose) and Viparita Namaskar (Reverse Prayer Pose) help release tension. After week 20, a pregnant student should no longer lie flat on her back for any extended length of time, due to the weight of the uterus and baby on the vena cava (a major vein carrying blood from the lower body back to the heart). Poses such as Supta Padangusthasana (Reclining Big Toe Pose), Supta Baddha Konasana (Reclining Bound Angle Pose), and Supta Virasana (Reclining Hero Pose), which increase circulation to the legs, open the hips, and relieve the back, can be done on an incline by using blankets or a bolster to elevate the student's upper body past 20 degrees.
This trimester is a good time to introduce such pranayama exercises as Ujjayi Pranayama (Victorious Breath) and Nadi Shodhana Pranayama (Alternate-Nostril breathing). They teach a woman how to focus on her breath, which helps her relax, and they're also good practice for breathing techniques that will help during labor and delivery.
As the belly grows, the abdominal muscles and ligaments are stretched taut; most strong abdominal poses such as Paripurna Navasana (Boat Pose) or leg lifts should be avoided so that the muscles don't separate or tear. Early in the trimester, the student can still do a few front-lying poses (Bhujangasana [Cobra Pose], or Salambhasana [Locust Pose] done with the upper body only); place a rolled blanket under the hips to make room for the belly. Later, these can be done with the chest and arms against the wall, the feet about 18 inches away, and the upper body leaning forward to make room for the belly.
Steer clear of any pranayama that involves retention of the breath (Viloma, or Interval Breath) or altering of the flow of air (Kapalabhati, or Skull Shining Breath), since either will affect the delivery of oxygen to the fetus.
Your student's new shape will also require modification of any poses that involve folding or twisting. She should spread her legs slightly and bend at the hip crease for all forward bends, to avoid compressing the belly. Open twists can relieve some of the back pain, but now the twist will happen above the waist and should not be too deep. Also, avoid teaching inversions and backbends. Most of these restrictions will be obvious, because the size of the student's tummy simply won't allow much of this activity, but make sure your student knows what poses can be modified and what poses she just shouldn't do.
The Fun Trimester (Usually)
Help your student enjoy the energy of this trimester by teaching her to modify favorite poses, or to substitute similar ones, so that she can still get the satisfaction of the stretch while acknowledging the changes to her body. Show her how the practice can deepen with close attention to how she arranges herself; she can still build strength and endurance while protecting her joints and growing belly.
