Hip mobility is the range you can use at the hip: rotation, flexion, and a long hip flexor. Intimate positions ask for those ranges when a knee drops wide, a hip opens, or a back leg extends. The five poses here are already in the Sexletics library or inside Mobility Unlock. Use them as a screen and as practice. The range that counts is the range you can breathe in and leave on purpose.
Work one pose, both sides, for a hold you can exit. The training log accepts a flexibility score from 1 to 10 for comfortable range. A higher score means that range felt easier today. Warm the tissue with a short walk or cat-cow before a long hold. Pain is a stop. Knee pain or hip pain ends the pose. Leave the flexibility score blank when pain showed up.
The 90/90 hip switch trains internal and external rotation. Sit with both knees bent near a right angle, one leg in front and one to the side, and switch while the spine stays tall. Move from the hips. Give both sides the same number of reps. Put your hands down when the back rounds, and shrink the range when you need momentum to arrive. Rounding the back and rushing the switch are the faults listed on the exercise page.
Supported pigeon is an external-rotation stretch for cool-downs and mobility sessions. Square the hips only as far as they go, and place a blanket under the front hip. Breathe into the sensation. Forcing the hips square is a fault, and so is ignoring the knee. When the front knee complains, use the regression on that same page: figure-4 on your back. Figure-4 is also the hip opener in Mobility Unlock week 1, held for two easy sets of about 45 seconds a side.
The cossack squat builds lateral hip range and adductor strength for asymmetric and deeply flexed positions. Keep the chest tall, the working heel down, and the other leg straight. Stop at a depth you can stand up from. A hand on a wall or a box is the regression when the torso collapses or the knee caves. Forcing depth is the fault to drop. The exercise page lists a pause in the bottom and a light goblet load as later progressions, after the bodyweight version is clean.
Happy baby is a supine open position: knees wide, feet toward the sky or held by a strap, low back easy, long exhales. The library uses it when tone is high and after harder work, because it gives the hips room and the belly a chance to soften. Forcing the knees to the floor, holding the breath, and tightening the neck are the faults. A figure-4 on the back is enough when the hands cannot comfortably hold the feet.
The fifth pose is a hip-flexor hold. Foundation Session A already programs it: a hip flexor stretch, two holds of about 45 seconds a side, inside a 35-minute session that also includes breath, hip circles, and glute bridge pulses. Couch stretch and the world's greatest stretch live in Mobility Unlock. The world's greatest stretch is the warm-up on the sample hip flow and on week 2. Couch stretch is a main-work hold there, about two sets a side, glute lightly engaged. Those two stretches do not have their own exercise pages. Week 1 of Mobility Unlock is the screen: easy marching, cat-cow, hip circles, 90/90 at comfort depth, and figure-4. Premium opens intermediate training, including that programmed week. The exercise pages stay open.
If this is your first block, pair one pose with Session A and repeat it for a few sessions before you decide anything changed. Keep the joint comfortable, stop at pain, and warm the tissue before a deep hold. That is the Mobility Unlock safety standard, and it covers every pose on this page. Log the flexibility score only for range that stayed comfortable. This is adult training education. It is not medical advice.
