What cardio is easiest on sore knees?

Options that are usually well tolerated

• Stationary or outdoor cycling: smooth, repetitive bending with little impact; seat height matters
• Swimming and water walking: water takes much of your body weight, and cool pools are a relief in a Qatar summer
• Cross-trainer (elliptical): a walking-like movement without the foot strike; keep the resistance moderate
• Walking on flat ground: still excellent for many people, especially on a track or in a mall
• Rowing machine: fine for many knees, but the deep bend at the front of the stroke can irritate kneecap pain
• Seated arm cycling or upper-body circuits: useful on days when the knee is flaring

How to start

• 1. Pick one option and begin with 10 to 15 minutes at an easy pace where you can still talk
• 2. Check the knee that evening and the next morning
• 3. If there is no extra pain or swelling, add about five minutes every few sessions
• 4. Aim to build towards around 150 minutes of moderate activity a week, spread over several days
• 5. Mix two types if one starts to irritate the knee

What tends to aggravate sore knees

Running downhill, jumping, stair machines, steep incline treadmill walking and classes with lots of lunges or pivoting usually load the knee more. They are not banned, but they are better added once the knee is calmer and stronger.

When to stop and get the knee checked

Stop the session if pain becomes sharp, the knee catches or locks, or it feels like it may give way. If every form of cardio hurts, the knee keeps swelling, or pain is waking you at night, book an assessment with a knee specialist in Doha so the cause can be found.
