The following exercises will develop psoas muscles and other hip flexor muscles.

Step-ups.
Cable hip flex machine
Sit-ups
Hill runs
Hanging leg raises touching hands with the foot.
Multi hip machine
Hurdle walk overs.
Weighted pants (doing high knees)
High knees for strength endurance

Tendon compliance and be developed with ballistic stretching.
Short duration static stretching.
PNF stretching.
Grass sprints.
Plyometrics (low volume).

Tendon stiffness
Large volume of strength training
Resistance work
Plyometrics (high volume)
Sprinting on hard surfaces.

Nice summary. However wouldnt step ups be better as a hip extensor exercise since the hip flexion movement isnt really resisted its the hip extension movement that will move the weight?
