FOUR REASONS WHY HIP FLEXORS FEEL TIGHT WHEN RUNNING

REASON:

They are being asked to do too much during early swing as the calf isn't strong enough to generate enough force for propulsion.

FIX:

Calf raises can help.

And this.

REASON:

They're weak and fatigue easily, creating a feeling of 'perceived' tightness.

FIX:

Hip flexion strength work can help.

REASON:

They are genuinely tight and there's a barrier to hip extension.

FIX:

Eccentric loading into hip extension can help.

And this.

REASON:

An anterior pelvic tilt and lumbar extension is utilised as a strategy as opposed to true hip extension - leading to an over-reliance on the hip flexors.

FIX:

Learn to hinge on a neutral pelvis to achieve full hip extension without anterior pelvic tilt.

And this.
