Hip Flexor and Muay Thai

[curlyface]

I've been training Muay Thai for 8 months now and love it. Over those 8 months I've got into way better shape, more flexible, stronger, and my technique has greatly improved. What hasn't changed, though, is my hip flexor continues to be a very weak point for me. Constantly in pain at the hip when doing flutters, bicycles, leg raises (all ab exercises), kicks on the pads, knees, everything. How do I get my hip flexor caught up with the rest of my muscles? My legs are pretty thick and I believe that they may be too heavy for my hip flexor which may have never been trained. Help

Load with weights, specific to goals, and flex the hip. The same as training other tissue.

I think the reason why there is such a lack of emphasis on training hip flexion is because people tend to think tight = don't need to be trained.

I think it would be safe to say that the majority of the population have WEAK and TIGHT hip flexors.
