Begin the Seated Hip Stretch on the ground with both legs extended in front of your body. Bend one leg, crossing it over the other, and use the opposite elbow to push the bent knee towards your body. You should feel the stretch in your hip. If your shoulders are tight, you might feel a stretch here as well. Reverse legs and repeat.
A similar but alternative form of this stretch is to grab your knee and pull it towards your body. Both are effective and can be performed individually or sequentially.
