The hip flexer is the only stretch that i think people know, needs to know, in the hip flexer. You can do it anywhere. It takes no equipment whatever. And it's the most effective one that i've given people over the ears to stretch. But tat comes, it comes with a caviot. People need to know this. From my experience, stretching does not produce lasting results regarding the aligment of your body. Sohe the deep philosophy that i believe, is the future. And i think, i think it's, it's to come.
