When it comes to which elements of your stride you can improve, your hips don’t lie. That’s because hip flexors—the muscles that allow flexion at the hip joint—play a huge role in fluid running, and a set of tight ones can really mess with your mechanics.

The iliopsoas is the strongest group of muscles in the hip flexors, connecting the spine to the femur, and it’s what helps contract and pull the thigh toward the torso, allowing you to bring your knee toward your chest.

Strategically opening and strengthening your hip flexors needs to be part of your routine. The easiest place to start is with active warm-up drills that are often underrated and underutilised. Two to three minutes of high knees, butt kicks, skipping, and running backward will open up the hips in the front, side, and back planes of motion.

Incorporate strength work in different planes of motion to keep all the muscles in and around your hip flexors, especially your glutes, firing correctly. You can’t have good hip flexion if your glutes are tight or weak, it’s important that you’re always stretching and strengthening the front of your hip flexor and the back, which are the glute muscles.

Whether you’re at the gym or just training at home , these five moves will strengthen and open your hips, keeping them loose long-term. Below,  is five hip stretches.
