Funcionou comigo, agora estou tão flexível que penso em trabalhar combatendo o crime como homem elastico.

Totally worked for me. Got several more inches and I’m really tight/inflexible. I’m wondering if it’s because of the principle where clenching/using strength in a muscle allows it to release after. I use this technique a lot in other stretches (often using dynamic stretching now instead of static) but I’ve never considered it in this stretch. Wonder if it has more to do with the back than the hamstrings?
