According to recent research, many of us sit upward of 10 hours a day, which means our butt muscles, or glutes, are constantly compressed. Simanksy recommends mashing your glutes on a foam roller or lacrosse ball to bring blood flow to the area to help rejuvenate the tissues.
Try it: Position yourself so your sit bones are centered on the roller. Cross one ankle over the opposite knee and lean onto the glute of the leg that's crossed. Spend two minutes per side, rolling up, down and around the glute muscles, and zeroing in on any tight, knotted spots.
