That's what i suspect too. I think the 150m tempos get them too, as i try to do them not 'stride-style' but 'sprint-style': i don't start 100% and then let momentum carry me, i treat them like normal sprints, keep pushing at each stride, just not 100%. I feel i get a much better training effect that way, strides are too easy, only use them as warmup.

In contrast, strengthening the hip flexors can be advantageous for people in posterior tilt as strengthening them will put your pelvis at a position that is more advantageous to engage your glutes. See if you have sufficient strength in your hip flexors. Place one foot up on a box so that your thigh is up above parallel. Then raise the foot up and hold it for 20 seconds without bending your support leg or squirming around.

If this test is at all difficult you could probably benefit from stronger hip flexors. To strengthen them, simply incorporate that test for a couple of sets 3 days per week. Another exercise I've found very helpful for posterior tilt is something I call a "hip suck". Lie down on your back with your legs straight and touch the area where your upper thigh inserts into the hip. Next, without bending your knee, attempt to draw the hip into the socket of the hip joint. You should feel a deep feeling in the groin. Try to relax your thigh while doing this. Hold the position for 10 secs. Repeat for 10 contractions. You can also do this standing up just make sure you don't compensate by bending your plant leg and leaning sideways.
