Hip mobility, for a lifter, comes down to two positions. In the squat, your hips bend deeply as your thighs come toward your chest. In the hinge, your hips bend with your knees nearly straight, and the backs of your thighs set the limit. If you can reach both positions under control, your hips have the range your lifts use.
This page covers why hip range matters for those two lifts, simple checks, the drills (90/90, hip flexor and adductor positions, loaded range work), and what the evidence does and doesn't show. It's about training range for lifting, in a healthy hip. The general ten-minute routine for ankles, hips, upper back and shoulders is the mobility routine, the ankle side of squat depth is ankle mobility, and how deep to squat is on squat form.
Why hip range matters for the squat and the hinge
- Squat depth. In 101 healthy adults, hip flexion range was one of two measures linked with how deep the 64 men squatted; for the 37 women, the linked measures were at the ankle.1 In 18 healthy university students, those who could reach a full deep squat had more hip flexion and ankle range than those who couldn't.2
- Enough, not the most. In a comparison of 12 national-level male powerlifters with 12 recreationally trained men, the powerlifters had less hip flexion, extension and adduction, and less hip flexion went with more strength for their body mass. The authors' advice was to keep enough hip flexion to reach competition depth.3
These are links, not proof that more hip range makes a deeper squat. And some of the limit is bone: a deep squat stops when the thigh meets the calf, however flexible you are, and a difference between your left and right side can come from the shape of the joint rather than tightness.4 The target is enough range, under control, for the lifts you do.
Four checks
- The squat check. A bodyweight squat, feet where you'd put them under a bar, arms forward. Can you get your thighs at least level with the floor, heels down, back in the position you started in? If your heels lift first, start with your ankles. If they stay down but you can't go lower without your back changing position, the hips are the likelier limit.
- The hinge check. Stand with your knees softly bent and your hands on your thighs, and hinge until the backs of your thighs are fully stretched, back flat. For most people, the hands reach somewhere around the knees to mid-shin.
- The 90/90 sit. Sit on the floor with one leg in front of you, knee bent to a right angle, and the other out to the side, knee also at a right angle. Can you sit tall without your hands, then swing both knees over to the other side?
- Half-kneeling. One knee down, squeeze that side's glute and shift your hips forward. You should feel the front of that hip stretch before your back changes position. This is the range a lunge or a split squat uses.
None of these is a pass mark or a diagnosis. Use them two ways: left side against right, and you against yourself a month from now.
The drills
| Drill | How | Dose | The position it trains |
|---|---|---|---|
| 90/90 switches | Sit in the 90/90, swing both knees over to the other side and back, sitting tall | 2 × 6 a side | Turning the hip both ways |
| 90/90 lean | In the 90/90, lean your chest forward over the front shin, back long | 2 holds of 30 seconds a side | The bottom of a wide squat |
| Half-kneeling hip flexor stretch | One knee down, glute squeezed, hips shifted forward | 2 holds of 30 seconds a side | Lunges, split squats |
| Adductor rock-back | On hands and knees, one leg straight out to the side, rock your hips back toward your heels | 2 × 8 slow reps a side | A wider squat stance |
| Side lunge to the bottom | Wide stance, sit into one knee with the other leg straight, heels down | 2 × 5 a side | The inner thigh under control |
| Deep squat hold | Hold a doorframe, sit to the bottom, heels down | 2 holds of 30 seconds | Squats |
What the evidence says about these:
- Stretching adds range. A 2024 meta-analysis of 77 studies found regular stretching increased range of motion, and static holds and PNF stretching, a hold paired with a muscle contraction, produced more than dynamic or bouncing stretches. Neither the total time spent stretching nor the number of sessions a week was linked with how much range people gained.5
- How long to hold. A 2025 consensus statement of 20 stretching experts recommends two or three sets a day of 30 to 120 seconds per muscle for long-term range.6 The doses in the table sit at the low end of that.
- The 90/90 and the rock-back have no trials of their own. Neither turned up in a PubMed search for this page. They're in the table because they put the hip in the turning and widening positions a squat uses, not because a study tested them.
Loaded range work: your lifts count
- Lifting through the range worked as well as stretching. In 25 untrained adults, five weeks of full-range resistance training improved hamstring flexibility, hip flexion and hip extension as much as static stretching of the same muscles, and both beat a group that did neither.7
- The hinge too. In 18 healthy, physically active adults, five men and 13 women, eight weeks of straight-legged deadlift variations through a full range improved the sit-and-reach as much as static stretching did, and built more strength.8
- The review agrees. A 2023 meta-analysis of 55 studies found that lifting increased range of motion about as much as stretching, with one exception: training with body weight alone showed no significant change.9
So the range work that counts most is in your lifts: a goblet squat held at the bottom for a breath, an RDL or a good morning lowered until the backs of your thighs are fully stretched, a split squat with the back knee all the way down, a side lunge with a light dumbbell. If your lifts already reach their positions, they're doing most of the work. A paused bodyweight squat still practices the position, though in that review, body weight alone didn't add range.
What the evidence does and doesn't show
- It shows that stretching and full-range lifting both add hip range, and that hip flexion range went with squat depth in two small studies.
- It doesn't show that more range on a test changes how you move. In 20 healthy people with limited hip extension, three weeks of hip flexor stretching at home increased their hip extension on a passive test but didn't change how their hips and pelvis moved when they ran.10 No study above tested whether a gain in hip range deepens a squat.
- It doesn't set a target. No study above gives a hip angle a lifter needs, and the powerlifting comparison suggests more isn't always better.
And this is training advice for a healthy hip. If a hip hurts, or you're coming back from a hip problem, a doctor or a physical therapist is the right first stop.
Where it goes in your week
- Before lifting: the moving drills, 90/90 switches and rock-backs, plus a short squat hold, fit into the warm-up.
- After lifting or on a rest day: the long holds, for the reasons in the warm-up guide's stretching section.
- Only the area you need. If your squat stops at the ankle, start with the ankles; if your hinge stops early, put the time into loaded hinges before the squat holds.
- Retest every four weeks with the same four checks, and write down what changed.
If you'd rather not plan it alone
A list of drills is easy to write down and easy to skip; fitting the right ones into the days you lift, and checking whether your squat and hinge are actually changing, is the part a page can't do. Coaching is the version where your workouts are built around the days you actually have, and a weekly call looks at the week you just had and rebuilds the next one. Coaching for beginners explains how that works, and here's how to apply. Otherwise: tonight, do the four checks and write down which one stopped you first.
General education only, not medical advice. If you have a medical condition, are pregnant, or take medication, check with your doctor before changing how you train or eat.
