Though this series is safe and doable, let intuition and judgment be your guide. Who plays base and who plays flyer is generally determined by size, with the larger person taking the base position. The spotter, not pictured in our photos, can be any size. The spotter should take a stable stance, like Goddess Pose, standing next to the flyer and the base, and keeping his or her eyes on and hands near the flyer’s hips, ready to catch her if she falls. Nemer suggests settling into each pose for three breaths.
