Crossing your legs is not bad posture

A cliché about one of the most common positions has been debunked. It actually has many advantages.

Cross your legs
Crossing your legs is almost a natural position, chosen to feel more comfortable and at ease. But some argue that it's a position with several contraindications, as it damages the hips and knees, causes postural imbalances, and puts stress on the spine. This isn't true.
In reality, the instinct to sit with your legs crossed arises from a series of factors that give a feeling of well-being.
  • When you cross your legs, your body creates a sort of "block" that stabilizes your pelvis. This reduces the workload of your postural muscles, so your brain perceives the position as more relaxing. It's essentially a shortcut to being comfortable without effort.
  • Sitting for long periods of time can put pressure on the buttocks and lower back. Changing positions—even crossing your legs—helps redistribute your weight and avoid local discomfort (although not always ideally in the long run).
  • Our bodies tend to continually seek out micro-variations to avoid stiffness. Crossing your legs is one of these "automatic strategies," a bit like shifting your position in a chair without thinking.
  • Some people (often those with more hip mobility) find this position more natural. Pelvic shape and flexibility also influence how "spontaneous" it feels to do it.
Furthermore, sitting with your legs crossed is perceived as a more composed and even more elegant position. And for this reason, it has never gone out of style.

Now a study published in the journal Manual Therapy, Starting with a question to a panel of physiotherapists from around the world about what sitting position they recommend for proper posture, the study reached a conclusion that will reassure all those who love sitting crossed-legged: it doesn't damage posture and there are no contraindications. If anything, the experts' advice is to vary positions, as the body always benefits from movement.
