Heavy legs at 6 pm, ankles that by the end of the day leave the mark of your sock's elastic, tingling if you stay too long in the same position: if you work sitting down, you probably know this routine. The reason is mechanical. Blood in the legs climbs back towards the heart mainly thanks to the contraction of the calves, the so-called "muscle pump", and while you sit, that pump is switched off for hours. The solution, luckily, is just as mechanical: switch it back on, many times a day. Here is how.
Circulation exercises for the legs: the desk routine
These leg circulation exercises are done seated or standing next to your desk, with no equipment and no sweating. The goal is not to train, it is to pump. Repeat the block 3–4 times across the working day (for example mid-morning, after lunch, mid-afternoon).
| Exercise | How to do it | Dose |
|---|---|---|
| Ankle pumps | Seated, heels on the floor: lift the toes, then lift the heels, alternating at a steady rhythm | 20–30 reps per direction |
| Ankle circles | Leg slightly raised, draw large circles with the foot, in both directions | 10 circles per direction, per foot |
| Heel raises (calf raise) | Standing, hands on the desk: rise slowly onto your toes, lower over 2–3 seconds | 15–20 reps |
| Seated marching | Lift your knees alternately as if marching, back resting against the chair | 30–40 steps in total |
| Glute squeeze | Seated or standing, squeeze your glutes for 5 seconds and release | 10 reps |
| Half squat to the chair | Stand up and sit down, lightly touching the chair, arms forward | 8–10 reps |
Total time: 3–4 minutes per block. Done 3–4 times a day, they are more effective than half an hour of exercise concentrated in the evening, because they interrupt the stagnation while it is forming, not after the damage is done.
Why they work (and why they are not enough alone)
The calf is called the "second heart" precisely because each contraction squeezes the deep veins of the leg and pushes blood upwards, while the venous valves stop it from falling back. Ankle pumps and heel raises use exactly this principle. Seated marching and the chair squat add the work of thighs and glutes, large muscles that move far more blood.
If you are pregnant the pump is working against much more fluid than usual, and not all of these movements count for the same. Which countermeasures have actually been measured in pregnancy is covered in swollen legs in pregnancy: what really helps.
That said, no desk routine replaces real movement. WHO physical activity guidelines recommend at least 150 minutes a week of moderate activity: brisk walking is still the best exercise for circulation there is, because it combines calf pumping, breathing and an upright posture. The routine above is there to cover the hours in the chair; daily walking builds the foundation. If your problem goes beyond circulation (stiffness, back pain, low energy), the full plan is in how to break up prolonged sitting.
The habits that multiply the results
Exercises work better if you also sort out the surroundings:
- Stand up every 30–45 minutes, even for just 2 minutes: drink a glass of water, take a phone call standing up. The interruption matters more than the duration.
- Check your chair height: if the edge presses behind your knees, it compresses the very veins you are trying to help. Feet well planted, knees at about 90 degrees.
- Do not keep your legs crossed for long periods: it is not an absolute ban, but it is an extra avoidable constriction.
- Stay hydrated: dehydration makes blood more viscous and worsens the feeling of heaviness.
- In the evening, rest your legs: 10–15 minutes lying down with your legs propped against a wall or on cushions helps drain the swelling that has built up.
- If your doctor has prescribed compression stockings, wear them: exercise and compression work very well together.
The most common mistakes
- Doing them "now and then". One day of pumps changes nothing: it is daily regularity, for weeks, that changes end-of-day symptoms.
- Moving only your toes. Effective movement starts at the ankle, with full range: toes up, heels up. If the calf does not contract, the pump is not working.
- Making up for sitting only in the evening. Evening training is excellent, but it does not cancel 8 hours of continuous stagnation: little and often during the day is better, with evening movement on top.
- Ignoring causes that are not muscular. Swollen legs can also come from venous insufficiency, medication, hormonal or heart problems: exercises help, but they do not replace a medical assessment when symptoms are significant. To understand the possible causes better, read poor circulation in the legs: symptoms, causes and remedies.
When an assessment is needed
See your doctor without waiting if the swelling is in one leg only, came on quickly, and comes with pain, warmth or redness: this is a scenario to rule out straight away. Visible varicose veins, swelling that does not go away after a night's rest, or skin changes (dark colour, persistent itching around the ankles) also deserve a check.
A physiotherapy assessment is the right route instead when the picture is the classic one from sitting still (evening heaviness, stiffness, perhaps some associated muscle ache) and you want a routine built around you: how much you can load, where to start, how to progress without reigniting other problems. Start with the questionnaire with a Ri-Hub physiotherapist: 20 minutes on a video call to assess your situation and give you a concrete starting point.
In summary
Heavy legs in people who work sitting down are not destiny: they are the predictable result of a muscle pump that has been still for hours. Leg circulation exercises work if you respect three principles: full ankle range, little and often during the day, and consistency for weeks. Add standing breaks, a daily walk and legs-up rest in the evening, and in most cases you will feel the difference within a couple of weeks. And if the symptoms do not settle, do not guess: get yourself assessed.
If the swelling is concentrated in the ankles and appears mostly in the evening, the full picture, including causes unrelated to circulation, is in Swollen ankle: causes, what to do and when to worry.
