I concur with Kelly Baggett on this.
"1. Get your butt in gear
What do I mean by that? Simple. Get your glutes contributing more in all activities. One simple thing you can do is become more "glute-conscious." Get up and walk around with your hands on your hips and voluntarily engage your butt muscles. As you walk around throughout the day take a few moments and periodically and consciously engage your glutes each time your foot contacts the ground. The more you do this, the more you're strengthen the mind to muscle connections and the better your glutes will function."
It's also a great way to make lots of new guy friends! Don't forget to keep your hands on your ass!
