The Lunge and Reach is a great combination move that will activate your core, dynamically stretch your hip flexors, and mobilize your spine. Walk forward into your tall plank and step one foot to the outside of your hand, making sure your knee is aligned above the ankle. Ground down through your opposite hand as you reach your arm towards the ceiling and open your upper body towards your front knee. Finish with wrist circles, spending a few moments in this position. Placing your hand to the ground, return to your starting plank. Alternate each side, feeling the activation of your full body throughout this sequence and feeling a deep stretch in your hips.
