Fix Weak, Stiff Hips: The Squat University Hip-Mobility & Stability Sequence
Weak or stiff hips that limit squat depth or cause knee pain usually trace to a combination of restricted hip-capsule mobility and poor glute/lateral-hip activation, both of which respond to a short daily mobility-plus-activation sequence rather than more stretching alone.
Test your current pattern before picking drills Perform a bodyweight overhead squat or deep squat hold and note exactly where it breaks down (heels lift, knees cave inward, torso collapses forward)
Where the pattern breaks down points to whether the limiter is mobility, activation, or both, rather than guessing.
90/90 hip stretch 2 rounds of 60-90 seconds per side, daily
Opens hip internal/external rotation range that a stiff capsule restricts.
Anterior hip (couch) stretch 2 rounds of 60-90 seconds per side, daily
Opens hip extension range; a tight anterior hip is a common squat-depth limiter.
Banded lateral walks or monster walks 2-3 sets of 10-15 steps in each direction, before lower-body training days
Wakes up the glutes and lateral hip muscles that control the knee during a squat, complementing the mobility work above.
Goblet squat hold at end-range depth 3 sets of 20-30 seconds, 3x per week
Reinforces the new range under light load, so mobility gains transfer to the actual squat pattern.
Repeat the same squat test every 2-3 weeks Use the identical screen from step 1 and compare
Confirms the pattern is actually improving rather than just chasing a stretch with no measurable change.
Squat depth and knee tracking are commonly limited by a combination of restricted hip-capsule mobility (which blocks the joint from reaching end-range flexion) and under-active glutes and lateral hip muscles (which fail to control the femur once you're there).

Is this for you
- Lifters whose squat depth is limited by stiff or weak hips
- Anyone with squat-related knee pain linked to hip mobility or activation, not a diagnosed injury
- Not a substitute for an in-person physical therapy evaluation of a diagnosed injury or acute pain
Cautions
- This is general mobility and activation guidance, not a substitute for an in-person physical therapy evaluation, especially with existing pain or a diagnosed injury
- Mild stretch tension is expected; sharp or worsening pain during a drill is not, stop and consult a physical therapist
- Educational only, not medical advice
