What Is 90/90 Stretch Exercise?

The 90/90 stretch is a dynamic exercise that targets hip mobility and flexibility. It involves positioning the hips and knees at 90-degree angles, creating an L-shape with the legs. This stretch is particularly effective in addressing tightness in the external rotators, hip flexors, and adductors, promoting improved range of motion in the hip joint.

To perform the 90/90 stretch:

1. Begin by sitting on the floor with one knee bent at a 90-degree angle in front of you and the other knee bent at a 90-degree angle to the side.
2. Ensure that the front shin and back thigh form a straight line and that the other leg is positioned perpendicular to the front leg.
3. Hinge at the hips to lean forward, aiming to bring the chest toward the front shin while maintaining a straight back.
4. Hold the stretch for 15-30 seconds, feeling the stretch in the hip of the leg positioned to the side.
5. Repeat on the other side.

The 90/90 stretch is versatile and can be modified to focus on different aspects of hip mobility, making it a valuable addition to warm-up routines and flexibility training.

What Muscle Groups Are Targeted?

The 90/90 stretch primarily targets muscles involved in hip external rotation, internal rotation, and abduction. The specific muscle groups engaged during this stretch include:

1. External Rotators (Front Leg):
   • The muscles responsible for rotating the hip outward (external rotation) are engaged in the front leg. This includes muscles such as the piriformis, gemellus muscles, and other hip external rotators.
2. Internal Rotators (Back Leg):
   • Muscles involved in hip internal rotation are targeted in the back leg. These may include the tensor fasciae latae (TFL) and some of the hip adductors.
3. Hip Flexors (Front Leg):
   • The muscles that flex the hip joint, particularly the muscles along the front of the hip such as the iliopsoas, are stretched in the front leg.
4. Adductors (Back Leg):
   • The inner thigh muscles, known as adductors, of the leg positioned to the side are stretched during the 90/90 stretch.
5. Hamstrings and Glutes:
   • While the primary focus is on the hip muscles, the stretch also involves the hamstrings and glutes, especially as you lean forward and hinge at the hips.
6. Quadratus Lumborum:
   • The quadratus lumborum, a muscle in the lower back, may be engaged as you maintain an upright posture and hinge at the hips.

By actively engaging and stretching these muscle groups, the 90/90 stretch helps improve hip mobility, flexibility, and range of motion. It is especially beneficial for individuals looking to address tightness in the hips, improve posture, and enhance overall lower body flexibility.
