What does IR stand for in this exercise?

IR stands for Internal Rotation, which refers to the inward turning of the thigh bone within the hip socket.

Where should I feel this stretch?

You should feel a deep sensation in the outer hip and groin of the trail leg, rather than sharp pain in the knee joint.

Yes, you can modify the stretch by elevating your hips on a yoga block or leaning further back on your hands to reduce the intensity.

It is effective as a daily mobility drill or as part of a warm-up before lower-body strength training sessions.

Sit on the floor with both knees bent at 90-degree angles, creating a square shape with your legs.
Position your lead leg in front of you with the shin parallel to your torso and the trail leg out to the side.
Place your hands on the floor behind or beside you to maintain an upright, neutral spine.
Focus on the trail leg and slowly rotate your pelvis toward that back hip while keeping the knee grounded.
Gently press the inner ankle and knee of the trail leg into the floor to intensify the internal rotation stretch.
Hold the position for the prescribed duration while maintaining deep, diaphragmatic breaths.
Slowly release the tension and repeat the movement on the opposite side.
