Your hips and ankles play a big part in how you squat, walk upstairs, do lunges, land, run and pick things up from the floor. When one part can’t work through the range you need, the body often finds a workaround: the heel lifts, the knee drops inwards, the trunk leans too far forwards or the movement stops earlier than it has to.
Why the squat and lunge need both the ankle and the hip
The squat and lunge aren’t single-joint exercises. They need the ankle, knee, hip, pelvis and trunk to work together. The ankle lets the knee travel forwards, the hip allows you to sit lower and control the direction of the thigh, and the trunk holds position so the movement doesn’t turn into a fight for balance.
When the ankle doesn’t allow the knee to move forwards, the heel often lifts, the foot turns out or the trunk leans forwards more. When the hip lacks the control you need, the knee may drop inwards, the pelvis may tilt or you may feel uncertain in the bottom position. That doesn’t automatically mean injury, but it is a sign that the movement needs adjusting.
That’s why it’s not enough to say you have tight muscles. Sometimes range is missing, other times it’s strength in that range, stability, technique or a suitable exercise variation for your build.
How to spot what’s limiting you
The best test isn’t one magic exercise. It’s more useful to compare a few simple situations. If your squat improves noticeably when you hold onto support, range may not be the only thing limiting you — balance and confidence may matter too. If the main difference is between the right and left side in a lunge, it may be hip or ankle asymmetry, or pelvic control.
For the ankle, a lunge-to-wall variation is often used because it measures the ability to bring the knee forwards under load. It’s not a diagnosis, but a practical indicator. Pay most attention to side-to-side differences and whether the improvement carries over into your squat or lunge.
- Wall ankle test: try to move your knee towards the wall without lifting the heel and without the arch collapsing.
- Supported squat: hold onto a rig or TRX and see whether depth improves when fear of losing balance is removed.
- Goblet squat with a light load: a weight in front of the body can help you find a more stable position.
- Split squat or lunge: compare the right and left side, and how the foot, knee and hip work.

Practical drills to start with
Good mobility for training isn’t just passive stretching. You need range that you can use under control. That’s why exercises work well when mobility is directly linked to movement: the ankle in a loaded lunge, the hip in a split squat, a supported squat or a light goblet squat.
Start with a small dose and watch the response. Two to three sets of a few calm repetitions are often more effective than long random stretching. If the main exercise improves after the preparation, the drill is probably addressing the right limitation. If you only feel a stretch but the movement stays the same, try a different variation.
- Ankle lunges with the heel down: slowly move the knee forwards and return.
- Supported squat hold: hold on, breathe and look for a stable foot, not maximum depth at all costs.
- 90/90 hip transitions: train hip rotation actively, without pulling the knee with your hands.
- Split squat through a smaller range: keep the foot, knee and hip in a controlled line.

Mobility
A squat doesn’t have to look the same for everyone
Not everyone needs to squat to the same depth, with the same stance and the same foot width. Hip structure, femur length, ankle mobility and movement experience all affect which variation will feel stable. For some people a wider stance works better, for others a slightly raised heel or starting with a goblet squat.
Adjusting an exercise isn’t cheating. If elevating your heels or using weightlifting shoes allows you to squat stably and without pain, that can be a useful tool. It just shouldn’t hide the fact that the ankle or technique needs longer-term work. Similarly, a lunge doesn’t have to start with a deep step straight away; it can begin with a shorter supported split squat.
A useful rule: first find a variation in which you can move well today. Alongside that, gradually build the range and control that will let you expand your options.
How to fit mobility into your week
Before training, mobility should prepare you, not tire you out. If you’ve got squats, lunges or a functional class ahead, a short active preparation and gradual build-up sets are enough. Save long holds in end-range positions for outside your main performance, if they help you.
If you have a desk job, consistency often makes the biggest difference. One long mobility session a week usually won’t offset five days in one position. Short doses through the week, walking, strength training through a controlled range and targeted drills tend to be more practical.
- Before squats: 5 minutes of light warm-up, ankle lunges, a supported squat and build-up sets.
- Before lunges: foot activation, a split squat through a smaller range and checking the knee over the foot.
- Outside training: short 10–15 minute blocks for one or two areas, not a whole list of exercises.
- During the day: change positions more often, go for a walk, use the stairs and don’t sit in one position for too long.
When to ease off and when to get guidance
A mild stretch, muscles working or a feeling of uncertainty in a new position are normal. Sharp pain in the groin, knee, ankle or back is not something to push through with more range. The same goes if you notice tingling, swelling, clear one-sided weakness or the feeling that a joint is giving way.
A coach can help you choose a squat variation, set your stance, check how your foot is working and tell the difference between a technical issue and a situation where a physiotherapist or doctor would be more appropriate. That’s often quicker than months of random stretching from videos.
At ARENA GYM, hip and ankle mobility can naturally link into functional training, mobility classes, open gym and personal training. It matters most when it carries over into the movement you actually use.
A self-test is not a diagnosis
A squat, lunge or knee-to-wall distance can compare sides and change over time. It does not identify the cause. Pain, sudden range loss or worsening daily function needs individual assessment.
Common questions
If I can’t get into a deep squat, does that mean my mobility is poor?
Sometimes yes, but it’s not the only reason. Your squat may be limited by the ankle, hip, technique, body proportions, trunk stability, fear of the bottom position or an unsuitable exercise variation. That’s why it’s better to compare a supported squat, a goblet squat, a split squat and a simple ankle test first rather than automatically stretching everything at once.
Does the ankle really affect the squat that much?
Yes. During a squat and a lunge, the ankle needs enough capacity to let the knee travel forwards without the heel lifting or the arch collapsing. If that range is limited, the body often compensates with a bigger forward lean, turned-out feet or an unstable knee.
Should I stretch my hips and ankles before every workout?
It depends on your goal. Before training, a short dynamic warm-up is usually more practical: ankle lunges, a controlled deeper squat, active hip work and lighter build-up sets of the main exercise. Long static stretching is more useful away from performance or after training, if it helps you.
How often is it worth training hip and ankle mobility?
For most people, 5–10 minutes before training and 1–2 shorter standalone blocks a week is enough if you’re working on a specific restriction. More important than duration is whether a specific movement improves: the squat feels more stable, the lunge more confident and the foot collapses less.
When is it more than just stiffness?
Sharp pain in the hip, groin, knee or ankle, tingling, loss of strength, swelling, instability after an injury or things getting worse with light movement are not just normal mobility issues. In that situation, it’s better to ease off and discuss the next steps with a physiotherapist or doctor.

The goal isn’t extreme range, but usable movement
Hip and ankle mobility isn’t a separate discipline outside your training. It makes most sense when you connect it to a specific movement: the squat, lunge, walking, stairs, running or a functional class.
Start with simple observation. What’s happening with your heel, knee, pelvis and trunk? Then choose one or two targeted adjustments. If movement quality improves after a few weeks, not just the feeling of a stretch, you’re heading in the right direction.
