Do THIS instead of planks to maximize your core strength! While planks have long been hailed as the holy grail of core workouts, the hollow body hold is a game-changer. This dynamic exercise not only engages your abdominals but also targets your entire core, including your lower back, hips, and glutes. By maintaining a hollow position, where your lower back stays glued to the ground and your legs and shoulder blades are slightly lifted, you'll activate deeper layers of your core muscles, challenging them in ways you never thought possible.
