Open Hips
Extension: good.
Overextension: bad.
In the fitness world, you often hear the term open hips. What does it mean, though? In a simplistic term, it's the point at which your hips come forward, and your body "opens" to an upright position. A key aspect to this open-hip phrase: your spine is upright and neutral; it is in an optimal position.
A problem: people often overdo it. They hyperextend their back in hopes to compensate for any possible missed opening of the hips. Don't do this. When this happens, the back—particularly, the lower back—becomes compromised.
Just stand up. That's open, and that's sufficient.
