This is a very helpful and effective move for when you get off the plane. It helps activate your core. Begin standing tall, feet about hip-width distance apart and legs straight. Bend over folding at your hips so that you can place your hands on the floor about a foot in front of you. Slowly lower your body towards the floor by walking your hands forward, eventually ending up in a high-plank position. From here, walk your feet towards your hands, keeping your legs as straight as possible. Repeat the sequence for three sets of 8 to 12 reps.
