Hip Opening (Advanced)

The advanced hip opener is a seated 90/90 position — front shin and back shin both at right angles — finished with a slow forward fold over the front leg. The fold multiplies the stretch through the front hip's deep rotators, so it belongs late in a session, on warm muscles. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Sets & reps by goal

Goal	Sets × Reps	Rest
Strength	2 holds × 20-30 sec per side (upright, no fold)	20-30 sec
Muscle	2-3 holds × 30-45 sec per side with a moderate fold	30 sec
Endurance	1-2 holds × 60-90 sec per side with the full fold	as needed

Level — Advanced

Advanced — the fold is earned; the upright 90/90 sit is the prerequisite position.

Proper form — 5 cues

Build the 90/90 first: front shin parallel with the chest, back shin trailing at a right angle.
Ground both sit bones toward the floor before any folding begins.
Hinge over the front shin with a long spine — the breastbone leads, not the forehead.
Walk the hands forward only as far as the hips release without the back rounding hard.
Hold, then swap legs — expect the two sides to feel different, which is normal.

Breathing: Exhale slowly as you fold deeper; each breath out buys a centimetre the muscles will lend.

The 3 mistakes Maddy corrects most

Folding from the waist with a collapsed chest. A rounded slump moves the sensation into the back and lets the hip escape the stretch entirely. Fix: Shrink the fold until the spine can stay long, and measure progress by hip feel, not head height.

The back-leg side of the pelvis lifting off the floor. An airborne sit bone means the body is dodging the rotation demand the position was built to create. Fix: Prop the front hip on a folded towel and press both sit bones down before folding.

Loading a cold hip with the full fold. Deep rotational stretch on unprepared tissue provokes guarding and occasionally strains the groin. Fix: Enter after training or after several minutes of general movement, never straight off a chair.

Common questions

What makes the 90/90 fold an advanced stretch?

It combines three demands most hip stretches apply one at a time: external rotation of the front hip, internal rotation of the back hip, and a loaded forward fold on top. Anyone missing range in one link feels it immediately. The upright 90/90 without the fold is the honest intermediate step.

My back hip pinches in this position — what should I change?

The trailing hip is being asked for internal rotation it may not yet own. Widen the back shin's angle past 90 degrees, elevate the front hip on a cushion, and keep the torso upright for now. Train internal rotation separately with gentle windshield-wiper movements, then revisit the strict position in a few weeks.

How long until deep hip positions feel comfortable?

With four or five short exposures a week, most people notice easier sitting and deeper squats inside three to six weeks, while stubborn hips can take a few months. Consistency and calm breathing at moderate intensity beat heroic single sessions — range that arrives gradually is the range that stays.
