7. Core Rotation and Anti-Rotation (Plank)

How to do it: Begin on the ground on all fours. Rotate your arms so the creases of your elbows are facing outward, and place your hands shoulder-width apart, with your fingers spread wide. Push your hands firmly into the ground and press up into plank position. Keep your chin off your chest and your head in line with your spine. Hold the position for 30 seconds, and work to gradually increase the length of time in the pose.
