How to do the Weighted Bottle Hollow Rock
Starting Position:
Begin by lying flat on your back on a comfortable surface, like a mat or carpet.
Hold the water bottle with both hands above your chest, arms extended straight.
Body Positioning:
Lift your legs off the ground so that your feet are about 6 inches above the floor.
Engage your core to flatten your lower back against the ground.
Your arms should be extended overhead while gripping the water bottle.
Rocking Movement:
Slowly rock backward by leaning your torso toward the ground while keeping your feet elevated.
Aim to bring your shoulders slightly off the ground as you rock backward.
Maintain a smooth and controlled motion.
Return:
As you rock back, let your body naturally return to the starting position.
Make sure to engage your core throughout the movement to maintain stability.
Repetitions:
Perform 10 to 15 rocks to build strength and stability in your core.
Rest as needed between sets.
Tips:
Keep your movements slow and controlled to avoid any strain.
Ensure that your lower back remains pressed against the mat to protect your spine.
Focus on using your core muscles to initiate the rocking motion rather than relying too much on momentum.
