Setup
- Load the EZ bar with round weight plates on each side and secure them with collars to ensure a smooth roll.
- Kneel on a foam pad or mat with your knees hip-width apart and the bar positioned directly beneath your shoulders.
- Grasp the EZ bar with an overhand grip on the inner downward-sloping curves to reduce wrist strain.
- Tuck your tailbone to achieve a posterior pelvic tilt and brace your core to create a 'hollow body' position.
How to do it
- Inhale and slowly roll the bar forward, extending your body into a straight line while keeping your arms locked.
- Lower your torso as far as possible without allowing your lower back to arch or your hips to sag toward the floor.
- Exhale and initiate the return by pulling through your lats and squeezing your abs to roll the bar back toward your knees.
- Maintain a slow, controlled tempo (3 seconds down, 2 seconds up) and stop when the bar is directly under your chest.
Form checklist
- Keep your hips moving in sync with your shoulders; do not leave your glutes behind over your knees.
- Maintain a slight rounding in the upper back (protraction) to keep the serratus anterior engaged.
- Ensure your arms remain straight throughout the entire range of motion.
- Stop the forward roll immediately if you feel any tension or 'pinching' in your lower back.
Pro tips
- Think about 'pulling the floor toward you' with your lats to initiate the upward phase rather than just pushing with your hands.
- Squeeze your glutes as hard as possible throughout the movement to lock your pelvis in place and maximize abdominal tension.
Make it harder
- Add a 3-second isometric hold at the point of maximum extension.
- Perform the rollout at a slight diagonal angle to increase the demand on the obliques.
