MobilityBWMat
Yoga hip opener that stretches the glutes and hip external rotators of the front leg while stretching the hip flexor of the back leg. Deep, passive complement to the 90/90 switch.

Sets

Reps
60-90 sec hold per side
Rest
20s
Contraindications
Knee pain with the front leg deeply flexed — use a bolster and shallower angle.Setup
From all fours, bring the front shin across the body at an angle, back leg extended straight behind.
Execution
- 1Square the hips as much as possible toward the front of the mat
- 2Lower the torso forward over the front shin to deepen the stretch
- 3Keep the back leg long and hip pointing down, not rolled outward
- 4Hold and breathe, easing deeper as tension releases
Key cues
- Square the hips, don't let the back hip roll open
- Fold forward from the hips, not just the shoulders
- Relax the front glute into the floor
- Keep the back leg extended and active
Common faults
- Letting the back hip rotate open to fake more depth
- Loading weight into the front knee incorrectly, causing knee pain
- Rounding aggressively through the low back to force depth
- Skipping the modified/bolstered version when too tight
Tweaks
- Use a bolster or block under the front hip if it doesn't reach the floor
- Add a reverse pigeon (quad stretch) for the back leg
- Sphinx pigeon (forearms down) for a gentler variant
Regressions
Muscles
Primary: Glutes, Hip External Rotators
Secondary: Hip Flexors, Adductors
Notes
Considered the modified/dynamic cousin of the 90/90; use both for well-rounded hip rotation training.
