Does anyone know specificaly what hormones affect flexibility? People generally say that male hormones reduce it and female hormones increase it, but I can never find any more detailed info. Is it that test and other male hormones reduce flexibility, or do female hormones actually work to increase it? If test was responsible, it would seem like steroids would decrease flexibility, but I've never heard of such a side effect. Is there any way for a man to tilt his hormonal balance in favor of increased flexibility without losing a lot of muscle or developing breasts?
