Lordosis

[Confucius]

apart from "work your abs", I don't really know how to diminish lordosis.

Got any specifics ? Infos I found were always vague.

Lordosis is normal. I think what you mean is hyper or hypo lordosis.

-Hyper lordosis: Your lower back is arched too much. Also called "swayback" or "saddle back"
-Hypo lordosis or lower kyphosis: Your lower back is arched the opposite of a normal curve. Like a hunchback but in the lower back.

To help resolve hyper lordosis, you need to stretch your glutes, hamstrings, and hip flexors. Many different types of these are found on the main site. You also need to strengthen both your core(abs, obliques, transversal abs, and lower back) and your glutes. These exercises can be found in the above links.

If you have hypo lordosis however, you need to stretch your lower back with common back stretches and sprawl or cobra (http://www.trickstutorials.com/images/s80.jpg) stretches(make sure you target the lowest part of your lower back though). It may seem difficult at first but keep persevering. It is also highly recommending you also do everything explained for helping hyper lordosis because it will commonly augment the prevention of any lordosis in the future.

In this case, it is perfectly fine to stretch your back; contrary to what many other people advise against stretching your back. These types of lordosis are not injuries. They are conditions so stretching is beneficial if performed correctly.

You can stretch your lower back too in "hyper lordosis" if your lower back muscles have spasmed/are tight. Curl up in a ball and stretch it out, bring one knee over your body and twist the opposite way, and bend laterally. Also lay on a tennis ball, putting the tennis ball under your lower back and staying on it till it releases the muscle. These are what completely fixed me up. Although it will just keep coming back if you don't fix the activities that are causing it, so be aware in everyday life to activate your transversus abdominis and tilt you pelvis so your lordotic curve isnt as pronounced.

You should also strenghten your hamstrings.

Yes you can. But lower back flexibility isn't the biggest issue in hyper lordosis. If you have been experiencing symptoms and know you have have it for only a short amount of time(couple of months) the most important thing is to do what I explained in my above post. If you have been suffering from hyper lordosis for a longer time, your back will adjust according to your tight hip flexors and the higher part of the lower back will achieve more flexibility than normal(to accomodate your new center of gravity) and the lowest part of your lower back will lose flexibility and that's when you need to stretch it.
