Lordosis of the lower back may be treated by strengthening the hip extensors on the back of the thighs, and by stretching the hip flexors on the front of the thighs. Too much importance have been attributed to the abdominal muscles in maintaining a neutral spine position. They may help by pushing the internal organs against the spine hence alleviating the lumbar curvature but they can't rotate the pelvis backward while in a standing position. Also the lumbar erector spinae is not able to rotate the pelvis forward while standing, hence its strengthening is not to be avoided during lordosis treatment. Only the muscles on the front and on the back of the thighs can rotate the pelvis forward or backward while in a standing position because they can discharge the force on the ground through the legs and feet. Abdominal muscles and erector spinae can't discharge force on an anchor point while standing, unless one is holding his hands somewhere, hence their function will be to flex or extend the torso, not the hip. Back hyper-extensions on a Roman chair or inflatable ball will strengthen all the posterior chain and will treat lordosis. So too will stiff legged deadlifts and supine hip lifts and any other similar movement strengthening the posterior chain without involving the hip flexors in the front of the thighs.

The worst thing you can do for lordosis is work your lower back even more. This will only exacerbate the problem. At the moment tight hip flexors are pulling the pelvis down at the front, while tight erectors are pulling it up at the back, so it's tilted downwards. As the Whippet said, you need to hit your abs hard and stretch out those hip flexors in order to pull the pelvis back into alignment. I'd suggest doing standing ab pulldowns for your abs - they need to be strong, so you need to hit them with some heavy weight.

anterior pelvic tilt'll make your ass stick out more and look bigger.

the second one is from a vegan source so it should be ignored.

Belly too! Anyone has a killer stretch for hip flexors? I've just started messing with this one

but thats stretching the quads and not the hip flexors, yeah?

interestingly, the stretch I do is a cross between that one I mentioned from the article and the samson stretch.

And just like that, the "Bob Stretch" is born. I love naming exercises after myself.
