Rotating Plank- Start in a low plank with a dumbbell positioned between your forearms.  Maintaining core stiffness, grab the dumbbell with your right hand and roll into a side plank.  Right arm will perform a rear fly movement with the dumbbell as you open your chest.  Return to the starting position and repeat the movement to the left, holding the dumbbell with your left hand.  Continue alternating sides for a total of 16.

Marching Bridges- Lie down on your back with knees bent.  Press your feet into the floor and roll your pelvis up into a bridge position.  Head, shoulders and both feet are on the floor, hips are pressing up.  From this bridge position, begin “marching” your feet, lifting one foot and then the other a few inches off the ground.  Try to initiate this movement from your hips and glutes, not your back.  Work to keep the entire core musculature engaged and not let the hips dip or sway side to side.  Perform 10 “marches” on each side and then lower your hips down to the floor for recovery.
