If your hips feel “tight,” stretching is often the first thing people recommend. Stretching can feel good and may temporarily increase range of motion, but flexibility alone does not give you strength or control in that range.
That is why I like using the 90-90 position as more than a stretch. It can become an active hip-strength and mobility drill that helps you work on rotation, control and confidence through a range of motion.
What Is the 90-90 Position?
In the 90-90 position, both hips are placed into rotation at the same time. The front hip is primarily in external rotation, while the back hip is primarily in internal rotation.
You do not need to force both knees perfectly to the floor or create exact 90-degree angles. Use a position that feels manageable and adjust your stance as needed.
Mobility Is More Than Flexibility
Flexibility describes how much range is available. Mobility includes your ability to actively move into and control that range.
For example, you may be able to push your leg into a position with your hands but have difficulty lifting or holding it there without assistance. Strengthening through range can help make mobility more usable.

Why Hip Rotation Matters
The hips move in several directions, including flexion, extension, abduction, adduction and rotation. Internal and external rotation show up in walking, turning, squatting, changing direction and many sports.
The goal is not to maximize rotation. It is to have enough comfortable range and control for the activities you want to do.
1. Lying Hip Rotations
If seated 90-90 feels too demanding, start on your back.
Place your feet wider than hip width with the knees bent and slowly allow the knees to move side to side like windshield wipers. Keep the range comfortable and let the hips explore rotation without forcing the movement.
Try 5–10 controlled repetitions.
2. Supported Seated 90-90
Sit in a 90-90 position with your hands behind you for support.
Allow your weight to shift between the hips while keeping the movement comfortable. The hands reduce the amount of strength and mobility required and make this a good progression before sitting unsupported.
3. Seated 90-90 Without the Hands
When the supported version feels comfortable, try taking the hands away.
You may immediately notice more work through the hips and trunk. Sit as tall as you comfortably can, but do not force an upright posture if your current hip range makes that difficult.
4. Back-Foot Lift
From the 90-90 position, keep the back knee on the floor and try lifting the back foot.
This challenges active internal rotation at the hip.
The foot may barely move at first.
That is fine.
Focus on creating the movement from the hip rather than twisting through the rest of the body.
5. Front-Knee Lift
Keep the front foot grounded and try gently lifting the front knee.
This challenges active external rotation.
Use a small range and avoid leaning dramatically to create movement.
Try 5–10 controlled repetitions.
6. Back-Leg Lift
Once you have more control, try lifting the entire back leg slightly away from the floor.
This is much harder than it looks.
The goal is not height.
A small controlled lift can provide plenty of challenge.
7. 90-90 Transitions
Move from one 90-90 position to the other by rotating both knees across the body.
You can keep your hands behind you at first, then gradually use less assistance.
This is one of my favourite ways to combine hip rotation with coordination.
8. 90-90 Hip Hinge
From the 90-90 position, gently hinge forward over the front leg.
Instead of collapsing downward, think about lengthening through the torso while moving from the hip.
You can use this as a mobility drill or add a light load once the movement feels controlled.
9. Transitioning Up From the Floor
The 90-90 position can also become part of floor-to-standing practice.
Use your hands at first if needed.
Gradually work toward using less support as your strength, balance and mobility improve.
Being comfortable getting up and down from the floor is a useful physical skill at any age.
Is Passive Stretching Bad?
No.
Passive stretching can be useful, enjoyable and appropriate.
The problem is only when stretching becomes the entire plan.
A complete mobility routine may include:
- passive stretching
- active mobility
- strength through range
- balance
- coordination
- regular movement
You do not have to choose between stretching and strengthening.
Strength Through Range
One reason I like 90-90 work is that it lets you strengthen hip rotation in positions where people often only stretch.
That may include:
- holding a position actively
- lifting the foot or knee
- transitioning between sides
- hinging
- getting up from the floor
This can help build confidence in ranges that initially feel unfamiliar.
What If 90-90 Feels Uncomfortable?
The position is not appropriate for everyone in the same form.
Try:
- sitting on a cushion or yoga block
- opening the knee angles
- leaning back onto the hands
- using the lying-down version
- reducing the range
If you experience sharp hip or knee pain, stop and choose another exercise.
Does 90-90 Prevent Injury?
I would not use it that way.
Strong, mobile hips may support many physical activities, but no single exercise prevents injury.
Injury risk depends on training load, previous injury, sport demands, recovery and many other factors.
Think of 90-90 work as one way to build hip capacity, not as protection against every future problem.
90-90 and Knee or Back Pain
Hip mobility and strength can influence how you move, but hip exercises do not automatically fix knee or back pain.
Pain is more complex than one tight muscle or one limited joint.
If pain is persistent or worsening, an appropriate healthcare or rehabilitation professional can help determine what is contributing.
How I Program 90-90 Work
For many people, I use 2–3 variations at a time.
A simple session might include:
- 5–10 hip rotations per side
- 5–8 foot or knee lifts
- 5–8 90-90 transitions
- a short supported hold
You do not need to exhaust the hips.
Slow, controlled repetitions are usually more useful than forcing range.
Strength and Mobility Belong Together
The goal is not simply to become more flexible.
It is to have enough range of motion and enough strength to use it.
That is why I do not just stretch hips.
I strengthen them too.
