Using PNF (proprioceptive neuromuscular facilitation) stretching technique to enhance the stretch of the hip flexor muscle, also called the ILIOPSOAS. This technique involves contracting the intended muscle to engage and fatigue it, while subsequently, inducing a maximal stretch past the normal static barrier of the muscle. This technique helps in providing a maximal stretch of the tissues. #iliopsoas #iliopsoasstretch #psoas #psoasstretch #iliacus #hipflexor #groin #anteriorhip #hipstretch #gro
