90-90 Hip Rotation After 40: The Exercise Your Hips Need

Chest, biceps, abs – the full programme. Yet when you push yourself up from the floor, you catch for a moment. The movement feels stiff, your hand automatically reaches for your hip, and there is that brief flicker across your face that so many people over 40 know. Nothing dramatic. Just that quiet “Ouch” you smile away as though nothing happened.

We happily talk about backs, six-packs and cardio. Hips, though? They tend to be filed under “not important”, much like that drawer at home full of things you mean to sort out one day. Until your hip starts making itself known. When you get up from the sofa, bend down to unload the dishwasher or make that first quick sprint for the train. Suddenly, you realise: Something is missing from my training.

Why our hips suddenly become a problem after 40

Most of us spend our time sitting: in the office, in the car, at the dining table or on the sofa with a laptop. That leaves the hip stuck in a position it is really designed to occupy only briefly: slightly bent, comfortably idle and with no real job to do. Add the usual “Quick, I still need to fit in a workout” and the energy goes into the upper body or fast cardio sessions. The hips remain spectators.

The body can compensate for this for a while. During your thirties, strength, determination and adrenaline can make up for plenty. After 40, however, it starts presenting an honest account: hip flexors tighten, the glutes become half-asleep, and mobility quietly diminishes centimetre by centimetre. All at once, a deep squat can feel like a risky expedition. You find yourself saying things such as: “I used to be more mobile somehow.”

A trainer who has worked with recreational exercisers for 20 years once told me she can spot “over-40 hips” simply by how someone walks. The stride is a little shorter, the upper body does more work than necessary, and the feet take care of the rest. The hip itself seems like a manager who has stepped away from the day-to-day running of things. Let us be honest: hardly anyone stretches their hips every day or deliberately activates the deep muscles in that area. We only notice when something hurts, clicks or simply no longer does what it used to.

For the body, the hip is a junction linking the upper and lower body, directing force when you run, jump and lift. When it becomes stiff or weak, other structures have to fill the gap: the lumbar spine, the knees and even the shoulders. The bill then arrives as back pain, knee pain, a pulling sensation in the groin or that dull ache after prolonged sitting. It may look like a back issue and feel like a knee issue, but it is often a hip issue.

The 90-90 hip rotation: the one exercise almost nobody does

Ask hip specialists which single exercise could make a major difference for people over 40, and one name keeps coming up: the 90-90 hip rotation on the floor. There are no dumbbells, machines or spectacle involved. Sit on the floor with both legs bent at right angles, one in front of you and the other out to the side behind you. Then rotate in a controlled way from one side to the other without moving your feet. It does not look impressive. That is precisely where many training plans go wrong.

This exercise restores something everyday life takes away: active internal and external rotation at the hip. It is not merely a stretch, but guided movement. The deeper muscles around the hip socket wake up, the glutes once again become a stabilising anchor, and the lumbar spine gets some relief. People who make time for it regularly often notice within a few days that getting up feels easier and their stride becomes freer. It is no surprise that many physiotherapists use this position like a reset button.

The first time you try it, your body is quickly honest with you. One side may move reasonably smoothly, while the other feels as though the handbrake is on. That is exactly where the work begins. Many people stop because they think: “I can’t do this, so it isn’t for me.” In reality, the opposite is true: Precisely because it feels stiff, this is exactly the exercise for you. With 5 to 10 slow rotations per side, no striving and just focused attention, you create a foundation for much else in your training.

The 90-90 position achieves something traditional stretches rarely do: it brings stability and mobility together. You sit securely on the floor, but your hip has to work to carry you from one side to the other. This creates a calm, controlled burn deep around the joint. Many people describe it as a mixture of “unfamiliar” and “liberating”. If you breathe deliberately and keep your upper body upright, you also train core tension without particularly noticing it.

How to make hip training part of everyday life

Even the best exercise is useless if it remains a forgotten YouTube bookmark. A practical approach is to attach the 90-90 hip rotation to something you already do every day. For instance, spend three minutes on the floor after brushing your teeth at night. Or do it before your first cup of coffee, still in your sleep shirt. It should not be a ritual that demands discipline; rather, a small habit that quietly runs alongside your day. That is how “I should train my hips” becomes an unremarkable part of daily life.

For a starting routine, keep it simple: sit in the 90-90 position, take one deep breath, then rotate slowly from one side to the other. Do 6 to 8 repetitions, take a brief rest and complete two rounds. If you wish, place your hands behind you for support; later, you can try moving them further forwards. The more upright you can sit, the more of the work your hips take on. The goal is not an acrobatic social-media move, but that quiet sense that “movement is coming back”.

People commonly make two mistakes with hip training: too much force and too little patience. Thinking, “I need to make this really intense now” often means throwing yourself into the stretch, gritting your teeth and hoping that explosive effort works for mobility too. It does not. The hip is sensitive and quickly responds with protective tension when it feels rushed. The second mistake is stretching without ever activating: spending a long time hanging in positions without actually engaging the muscles.

Anyone who has started looking after their hips after 40 knows that a little kindness towards your own body achieves more than heroics. One physiotherapist summed it up rather dryly:

“The hip is like an old hinge. If you move it a little every day, it stays quiet. If you ignore it for years, it squeaks with every movement.”

A short mental checklist can stop hip training from disappearing into the “I’ll do it sometime” void again:

• Choose a fixed moment in the day; no more than 5 minutes is needed, and short is better than perfect.
• Use one exercise as your base, the 90-90 position, rather than ten different variations.
• Move slowly and with control; do not collapse into the position or bounce.
• Mild discomfort is acceptable, but sharp pain is a signal to stop.
• Once a week, consciously notice: does getting up, walking or climbing stairs feel different?

Why looking after your hips is about quality of life, not athleticism

If you can sit on the floor at 45 and stand up again without thinking about it, that does not automatically make you “fit” in the conventional sense. But it does mean you have retained something that barely registers in everyday life until it is gone: freedom of movement. The hip plays a leading role in this, even though it rarely takes centre stage. It helps determine whether you can play with children on the carpet, spontaneously get into a kayak on holiday or lift a crate of water at the supermarket without pulling a face.

Interestingly, people who begin taking their hips seriously often report unexpected side effects. Their backs complain less. Their stride becomes longer and more relaxed. Confidence in their own body returns because movements they had unconsciously avoided suddenly become manageable. They spend less time worrying about whether they might “put their back out”. Their body starts to feel more like an ally again, rather than a risk to be navigated with caution.

Perhaps that is the hidden benefit of hip training after 40: you start listening more carefully again. Rather than adding another set of biceps curls, you give yourself two minutes of hip rotations. Instead of focusing only on running faster, you work on taking cleaner steps. It sounds unremarkable, almost boring. Yet it contains a quiet form of self-care that reaches far beyond muscles. By getting your hips moving again, you create room to move – now and for the decades ahead.
