– Come into a full plank. From the side view, your shoulders should be stacked on top of your hands
– Engage your core and squeeze your buttocks so that your body is in a long straight line
– Perform a pushup, then rotate your body into a side plank (an easier version is to keep the other arm supported on the floor in front rather than pointing it to the ceiling)
– Drop your hips to the floor and raise again
– Complete your reps, then switch sides
