Butterfly pose is one of my favorite hip openers, and there are many Partner Yoga moves that involve this pose. There's the Butterfly Pull, Butterfly Supported Forward Bend, and Seated Butterfly Lounge is great way to stretch. If you have tight hips then you will appreciate trying Back-to-Back Butterfly with a partner since this variation deepens the stretch and it is only slightly hands-on compared to a couple of other partner poses.

• Partner #1 and Partner #2 sit with their backs touching and their legs out in front of them. They each bend their knees and come into Butterfly.
• Then they reach their arms behind their backs and rest their palms on their partner's knees.
• If it feels OK, each person gently presses down, increasing the intensity of the stretch in their partner's hips. It's important to communicate here. Each person should tell their partner to push harder or push less.
• They stay like this for five breaths or more and then release.
