Lordosis or or excessive curvature in the lower back (lumbar spine) is very
common among the sedentary population because of muscle imbalances.
You most likely have very tight hip flexor muscles, which are the muscles
which would lift your knee as if you were marching and your glute muscles are
Together this causes your hip bone (pelvis) to rotate forward which pulls the
spine into lordosis.
No Quick Fix
What I just explained happens over years of bad posture, inactivity or training
abs and other body parts improperly so there is really no "quickest possible
You cannot expect to reverse something which developed over 5 years in
days, weeks or even months.
You can begin correcting your lordosis by stretching your hip flexor muscles.
You can do so with the stretch to the right. You should probably stretch
each side for 30-45 seconds 2-3x a day and more if you sit for extended periods
Your next priority should be to strengthen your glutes which you can do by
bridges and most leg exercises with good form especially lunges.
Core exercises will also help you tighten your mid section by strengthening
the muscles which support your lower back. Perform core exercises (http://www.askthetrainer.com/best-core-exercises/) only if you are able
to pay close attention to form.
