Are your hip flexors weak?

The exercises shown will not help your sprint speed, and they wont do a lot for the hip[ flexors either.

Unfortunatley, the psoas are a complex muscle group that would require pages and pages to explain what does and what does not help them. (And half of those pages would be the chore of debunking myths.)

Here’s a few points (and no way near the full scope of the subject.)

1. Standing cable flexion knee lifts and standing bungee cord knee lifts are a bad idea.
   (the more resistance you use, the more it becomes an isometric strength exercise for hamstroings and calves of the support leg on the ground. Do you really want isometric endurance in that position for your hamstrings which need to be the most dynamic muscle?) That for starters.

2. The more weight you lift in those exercises, the more your form suffers in that very exercise. The extra weight, tempts you to move in to posterior pelvic tilt, in order to still raise the knee to an apreciable hieght. But this would be conning yourself. The thigh angle relative to the pelvis (that is now posterior tilted) is actually a ‘low’ knee. That would be fine if it wasn’t so slow, and the support leg wasn’t bracing so intensely that your hamstring tendons become stiff as bridge cables, and loosing compliancy.

3. There’s more, but it takes too long.

Of the three main exercises, the worst is the standing knee flexions. The second worst is the theraband exercize. The laying cable exercize is not as bad.

As for the other exercises, I have not even considered them.

Then what exercise would you approve of for strengthening the hip flexors?
