It’s not just slumping that hurts your posture. Simply sitting can be harmful, too.  For instance, when you sit constantly—as most of us do—the muscles on the fronts of your hips become short and tight. What's more, your glutes—or butt muscles—actually forget how to contract. The combination of tight muscles on the front of your hips and weak muscles on your backside causes your pelvis to tilt forward. This pushes your lower abdomen outward, making your belly protrude—even if you don't have an ounce of fat. Worse, it also puts more stress on your lumbar spine, which can lead to lower-back pain.
