If you spend most of your day in a chair, your hips stay bent for hours, your hamstrings rarely lengthen and your lower back barely moves. Many people notice this as a stiff, "tight" feeling when they stand up after a long meeting or a drive. The good news is that a short, regular stretching habit, plus getting up more often, is simple, cheap and needs no equipment.

This guide gives you a 10-minute routine for the three areas people search about most (hip flexors, hamstrings and lower back), along with what the research says about how long to hold each stretch and how often to do it.

Why sitting leaves you feeling stiff

Research suggests that many adults spend more than 7 hours a day sitting, at work, on transport or in their free time.1 The NHS points out that you can meet your weekly exercise target and still be at risk of ill health if you spend the rest of your time sitting or lying down.1 That's why UK guidelines ask adults not only to exercise but also to break up long periods of not moving with some activity.2

Stretching isn't a substitute for moving more: the guidelines are about being active and sitting less.2 But stretching does something specific and useful: done regularly, it improves flexibility and, as a result, the range of motion of your joints.3 For a desk worker, that can mean moving more freely, getting into a squat more easily and feeling less stiff by the evening.

You may read online that sitting "shortens" your hip flexors. Whatever is behind the tight feeling, what is well supported is that regular stretching improves how far a joint can move, and that the improvement fades if you stop.3

The rules that make stretching work

Before the routine, here are the basics from Mayo Clinic's guidance on stretching safely:3

  • Warm up first. Stretching cold muscles can hurt. Walk, march on the spot or cycle gently for 5–10 minutes first, or stretch after a workout when your muscles are already warm.
  • Hold, don't bounce. Move into the stretch smoothly and hold it. Bouncing can injure a muscle and make it tighter.
  • Aim for tension, not pain. If it hurts, back off until it doesn't, then hold.
  • Hold for about 30 seconds. Breathe normally. Very tight areas may need up to 60 seconds.
  • Stretch both sides. Aim for even flexibility rather than extreme flexibility.

How long is long enough? In a classic trial, adults with tight hamstrings stretched 5 days a week for 6 weeks. Holding a stretch for 30 seconds increased range of motion just as much as holding it for 60 seconds, and stretching once a day worked as well as three times a day.4 For most people, one good 30-second hold per stretch is enough.

How often? Mayo Clinic suggests at least two to three times a week, and notes that even 5 to 10 minutes at a time can help.3 The NHS flexibility routine also recommends at least twice a week, building up slowly.5 If you sit every day, a short daily routine is an easy habit to stack onto something you already do, like finishing work or brushing your teeth.

A 10-minute routine for hips, hamstrings and lower back

Do this after a few minutes of easy movement. Hold each stretch for about 30 seconds per side unless noted, and breathe slowly.

1. Kneeling hip flexor stretch (front of the hip)

Kneel on a mat with one foot flat in front of you and the other knee on the floor behind you. Gently squeeze the glute of the back leg and tuck your pelvis under slightly, then shift your weight forward until you feel a stretch at the front of that hip. Keep your torso upright and don't arch your lower back. See the animated demo of the kneeling hip flexor stretch.

2. Lying hamstring stretch (back of the thigh)

Lie on your back, loop a towel, belt or band over the ball of one foot and raise that leg toward the ceiling, keeping the other leg flat on the floor. Pull gently until you feel tension along the back of the thigh. A slight bend in the knee is fine. Lying down keeps your back supported, so you can focus on the hamstrings. Here's the hamstring stretch demo.

3. Knee to chest (glutes and lower back)

Still on your back, pull one knee toward your chest, holding under the knee rather than on the kneecap, while the other leg stays long. Switch sides, then finish with both knees together for a few breaths.

4. Cat stretch (spine mobility)

On your hands and knees, slowly round your spine toward the ceiling, letting your head drop, then return to a flat back. Move slowly for 5–8 repetitions instead of holding one position. This gentle movement is a good way to "wake up" a back that has been still all day. Watch the cat stretch.

5. Child's pose (whole back)

From hands and knees, sit your hips back toward your heels and let your arms reach forward along the floor. Rest your forehead down and breathe into your back for 30–60 seconds. Skip this one, or put a cushion under your hips, if it bothers your knees.

That's about 10 minutes. Done after work, it doubles as a signal that the working day is over.

Build movement into the day, too

Stretching pairs well with moving more often. A few practical ideas:

  • Stand up and walk for a minute or two every half hour or so: refill your water, take calls standing or walk to a colleague instead of messaging.
  • Do one stretch from the routine each time you get up, such as the hip flexor stretch against a chair.
  • Pair stretching with strength. The guidelines recommend muscle-strengthening activity on at least 2 days a week,2 and moves like squats and bridges work the same hips and legs you're stretching.

When to get checked first

Feeling stiff after sitting is normal. Pain is different. The NHS advises staying active when you have lower back pain and trying gentle exercises and stretches, but stopping if the pain gets worse.6 See a doctor if back pain doesn't improve after a few weeks, stops you from doing everyday activities or keeps getting worse.6 Get emergency help for warning signs such as numbness or weakness in both legs or changes in bladder or bowel control.6 If you have a recent injury or a long-term condition, ask a physiotherapist to adapt the stretches for you.3

How to start this week

  1. Pick a trigger. Attach the routine to something you already do every day, like closing your laptop.
  2. Do the 10-minute routine on at least 3 days this week. Use the animated demos above to check your positions.
  3. Add movement breaks. Set a reminder to stand up every 30–60 minutes during work hours.
  4. Make it part of your training. If you want a structured plan, the 5-Day Transformation opens every session with stretching and has dedicated Stretch & Cardio recovery days. Open it in the TrainSmart app and tick off each session as you go.

Small, regular sessions beat an occasional long one. Give it two or three weeks and notice how much easier it feels to stand up from your chair.
