Viparita Salabhasana (Reverse Locust Pose) registers as 58* on BKS Iyengar’s 60* scale of difficulty in Light on Yoga.
BKS Iyengar explains that Viparita Salabhasana is more intense than Ganda Bherundasana. So, unless you’re feeling comfortable in Ganda Bherundasana, Viparita Salabhasana should probably remain unexplored.
Personally, I’m no where near ready for Viparita Salabhasana yet! Even the preparations for Ganda Bherundasana test my limits, so I choose not to explore this more advanced pose. If you feel ready for this pose, I invite you to seek the guidance of your most experienced teacher.
If, like me, you’re not ready for Viparita Salabhasana, continue to enjoy your practice where it is today. There’s no rush to “achieve” a pose. Embrace your practice as it is today.
