Okay guys, so I have an issue with doing stiff leg deads, and I'd like to be able to get more hip flexability and lower back flexibility, I can keep my legs straight and my back arched up until my hands get about 8 inches from the ground then it starts bending, this is dangerous. It has also made it where I have to use more leg movement in my deads which seriously hinders my deads strength. I'd like to get some advice on how the hell I can get flexible enough to keep my back in perfect form while being able to touch the floor with my hands and keep my legs straight. What kind of stretches/exercises/etc should I do to attain more flexibility. Thanks.
