Plank walk-outs

How to do it

1. Stand with your feet hip-width apart, then fold forward and place your hands on the floor in front of your feet - knees bending as much as they need to.
2. Walk your hands out, one in front of the other, until you reach a full plank with your shoulders over your wrists and your body in a straight line.
3. Pause, then walk your hands back toward your feet and roll up to standing.
4. Out and back is one rep: the further your hands travel, the more your abs pay for the trip.
