If you've ever stood up after a long meeting or a marathon flight and felt your legs heavy and achy, you've already felt the quiet pull of gravity and stillness. The good news? You can prevent blood clots with small, consistent movementoften while you're still sitting. Think of your legs like a gentle fountain: when they move, blood returns smoothly to your heart; when they don't, it can pool. Today, I'll show you eight friendly, do-anywhere exercises to boost circulation, plus smart tips for travel, desk life, and recoverywithout overwhelming you or your schedule.
Before we dive in, here's your quick-start: Try ankle pumps and calf squeezes every hour you're sitting. Keep your legs uncrossed, stand to walk when you can, and ask your clinician whether compression stockings are right for you. Tiny habits, big protection.
Why movement matters
What causes clots when you sit?
When you sit still, your calf musclesthe body's "second heart"go on break. Usually, each step squeezes blood up the veins toward your heart. Without those squeezes, blood moves slower and can pool in the lower legs. Slower flow plus vein wall irritation plus sticky blood is the classic recipe for a deep vein thrombosis (DVT). Long flights, road trips, and convalescing after surgery crank up that risk because stillness stretches into hours.
Who's most at risk?
Some of us need to be extra intentional. You're at higher risk if you've had recent surgery or a hospital stay, you're on bed rest, you're over 60, you've had a prior clot, you're pregnant or postpartum, you have active cancer, you take estrogen-containing hormones, or you're managing obesity. None of these mean you'll get a clot; they just mean your prevention plan (hello, seated exercises for circulation) matters even more. If you fit one or more of these, check in with your clinician about a personalized strategy.
Warning signs you shouldn't ignore
Here's your "don't-wait" list. For DVT: one leg suddenly swelling, warmth, redness, tenderness, or a cramp-like pain in your calf that doesn't feel like your usual workout soreness. For a pulmonary embolism (a clot that travels to the lungs): sudden shortness of breath, chest pain that worsens when you breathe in, fast heart rate, dizziness, or coughing up blood. If these hit, call emergency services. It's always better to be cautious.
8 best exercises
Do these blood clot prevention exercises every hour you're sitting for long stretches. Aim for about 3060 seconds per leg unless noted. Move gently, breathe normally, and stop if you feel pain. Ready?
1) Ankle pumps (seated)
How to: Sit tall with feet flat. Pull your toes toward your shins (dorsiflex), then point them away (plantarflex). Think of drawing water up and pressing it downsmooth, rhythmic, 12 seconds each direction. Do 3060 seconds per leg, or both together if that's comfy.
Why it works: Each pump squeezes your calf muscles, which propels blood up your veins toward your heart. It's the simplest, fastest way to wake up your "calf pump."
2) Ankle circles (seated)
How to: Extend one leg slightly, heel hovering or resting lightly. Slowly draw big circles with your toesclockwise for 1015 seconds, then counterclockwise. Keep the motion in the ankle, not the knee.
Pro tip: Bigger circles, not faster circles. If your knee is wobbling or your hip's doing the work, you're going too fast or too big.
3) Heel-toe raises (seated or supported standing)
Seated: Keep your heels down and
FAQs
How often should I do the clot‑prevention exercises?
Perform each set for 30‑60 seconds every hour you’re seated, especially on long flights or during prolonged desk work.
Can I do these exercises if I’m already on blood‑thinners?
Yes, the movements are safe, but always check with your healthcare provider to confirm they fit your medication plan.
Do I need special equipment for any of the exercises?
No special gear is required—just a chair, a stable surface, and optionally a small towel for ankle circles.
Are compression stockings necessary if I do the exercises?
Compression stockings can add extra protection, especially for high‑risk individuals, but they’re not a substitute for regular movement.
What if I feel pain or discomfort while doing the moves?
Stop immediately. Mild muscle stretch is normal, but sharp or lingering pain may indicate injury—consult a clinician.
