Side Planks
The side plank is one of the best full body stability exercises out there. This is a favorite of mine for personal training clients who have back and hip pain as it leaves no stone unturned. This exercise not only target the obliques, abs, and low back muscles, but also hits the shoulders and hip. The muscles of the rotator cuff and the hip stabilizers (particularly the glutes and TFL) get some good isometric work in during the side plank.
