How much daily sitting should a person limit themselves to?

Pay more attention to your posture and practice standing up under the strength of your legs, rather than worrying about how long you are sitting for.
Transcript: "My recommendation for sitting is less how often you sit. More, while you're sitting, are you paying attention to your posture? Or your hips splaying out? Or are you keeping everything tight together? And how often are you practicing standing up out of the chair under the strength of your legs, not pushing yourself out of the chair with your arms? That stand up and sit down process is far more important than how you're sitting, in particular. So don't worry so much about, how long am I sitting? Worry, what am I doing to reciprocate the internal rotation and compressions of sitting? That's much more important answer."
