Legs are more active in the recent pic and twist is also deeper, especially the arm reaching behind the back, that shoulder can move more so I can hold hands lower on the thigh. If you’re having a hard time with this asana, I recommend you involve your spine as much as possible, so the elbow passes the opposite thigh and reaches the outer part of it. As that arm wraps tightly around both hamstrings, avoid the temptation of folding forward (towards the legs) and, once more, twist away. This is a tough moment because you’ll likely be at your flexibility edge (spine can’t rotate more) so, push with elbow against leg to give you those extra few degrees and, on exhale, wrap with the other arm and reach fingertips towards each other like there’s no tomorrow! Once you lace them, it gets a lot better and crawling up to the wrist is tough, but not as hard as the previous phase. Keep knees somewhat bent until the twist is more natural, then work on straighten them... long breath, stay positive and let’s try. Give it your best shot keep going!
