Supine bridge stability test and exercise for runners

[Shortchange2006]

An important addendum to this video. If you really want to assess stability, particularly in the gluteous medius, you'll perform the bridge, then when kicking out the leg (making sure it stays parallel to the bent leg, you'll hold the leg extention for a 2 - 5 second count before lowering it slowly. If you notice a drop in the pelvis on the opposite side of the leg extension, it indicates a weakness or muscle imbalance.
