Standing Hip Flexor Stretch
This stretch doesn’t provide as intense of a stretch as the kneeling hip flexor stretch, but it can be done by almost anyone. That said, it’s common to have excessively tight hip flexors and this stretch is beneficial for most people. It can still be a little tricky, because the movement required for the stretch is often unfamiliar.
Start in a standing position with one foot forward and one foot back. Keep your feet about hip width apart and have the distance from your front food to your back foot be as far as you can comfortably stand with both feet flat on the ground. If your back heel comes off the ground, it nullifies the majority of the stretch.
You also want to keep both feet pointing directly forward and have good upright posture, in order to maximize the stretch on the hip flexor. Most people benefit from having something close by to hold on to, so they can focus on the stretch, instead of worrying about their balance.
For some people, just being in this position may be enough of a stretch, but the stretch can be significantly enhanced by moving your hips slightly forward. To do this, increase the bend in the front knee, but be sure to maintain your upright posture. It can be very tempting to lean forward, but it decreases the stretch.
The movement will probably be very small, but you should feel a decent stretch in the hip flexor of the back leg (front of the hip). If you do this correctly and still don’t feel much of a stretch, you should try the kneeling hip flexor stretch instead.
