Lordosis client

So, I've got this client whom I see weekly. Real sweet guy, but his lumbar spine thrusts so far forward, that his thoracic and cervical spine jut back at an incredibly retracted angle. Most sessions I apply heat to his back and neck, but was wondering if there was anything that I could do to adjust his back. I pieced through some massage literature on clients with lordosis, and found that the hip flexor muscles are typically working over hard (short, and tight) while the pelvic muscles are not working much at all (long, and loose). So the next time I see him, I am going to suggest working on his pelvic muscles, do some p.n.f, r.i., and stretches to engage and open up these muscles. Hopefully, by relaxing the hip flexor muscles, lordosis client's thoracic and cervical muscles won't be tugged on as much. I'll let you know what I find...
