Our bodies are shaped by every movement we make and, in particular, by those we do repeatedly. Those who sit repeatedly have short hip flexors, those who play the piano have increased mobility and control in their fingers, those who run marathons have leg muscles that have adapted to endurance use.

Do you wake up in pain?  Where you ache in the morning is an indicator of the areas of your body which need more attention.  If you consider the combined effects of gravity and our daily activities--driving, computer time, lots of sitting, it would make sense that our alignment is most poor after a long day. 

One of my favorite things in life is rowing a raft through the Grand Canyon on the Colorado River. Until eight years ago, this was my job: Grand Canyon River Guide. Every year, from April through October, I took passengers on wilderness rafting trips through beautiful, remote desert far from the rest of the world.

Your butt. Your derriere. Your po-po. Your tokhes. However you choose to refer to this area, we're talking about your glutes. While often a source of worry for vanity's sake, this isn't just about looking good. The glutes are one of the most important muscle groups of the entire body!
