The Half Butterfly Pose is an easy yoga move that can help boost your flexibility, posture, and muscle relaxation. This stretch targets the hips, hamstrings, groin, inner thighs, and knees, while also working to elongate the spine. You can practice this pose at any time of the day, and it is a great alternative for those who struggle with sitting in a cross-legged position. However, you should skip this exercise if you suffer from severe pain in your hips, knees, or ankles.
