Test your hip flexors range of motion & try a drill to help.

The primary hip flexors are a group of 6 muscles; the rectus femoris, TFL, iliacus, psoas, iliocapsularis, and sartorius muscles.

Rectus femoris - also one of the quad muscles

Tensor fasciae latae (TFL) - with the gluteus the TFL does wide variety of hip movements, including flexion, abduction, and internal rotation.

Iliacus - flexes and externally rotates the femur

Psoas - joins upper body to lower body

Iliocapsularis - stabilizes the hip

Sartorius - both a hip flexor and knee flexor
