What is legs touching when sitting?

Legs should not touch when sitting as it can result in poor posture, decreased blood circulation, and discomfort. Sitting with legs crossed or with one leg over the other can also cause strain on the hips and back. It is recommended to sit with both feet flat on the floor, knees at a 90-degree angle, and hips pushed all the way back in the chair. Adjusting the chair height or adding a footrest can also help achieve proper posture while sitting.
