The side plank works the obliques and the side of the hip.
Lying on your side, supported on your forearm, elbow under your shoulder, legs straight on top of each other.
Raise your pelvis to align your body from head to toe, and hold the position. Switch sides.
The hips must not drop or drift backward. Supported on the bottom knee, it is easier.
