Setup
- Stand upright with your feet shoulder-width apart and a slight bend in your knees.
- Place your right hand lightly behind your head with the elbow flared out to the side.
- Let your left arm hang naturally at your side or place your left hand on your hip for stability.
- Engage your core and maintain a neutral spine with your gaze forward.
How to do it
- Exhale as you slowly bend your torso directly to the right, aiming to bring your right ear and elbow toward your right hip.
- Contract your right obliques forcefully at the bottom of the movement, feeling the 'pinch' in your side.
- Inhale as you slowly return to the starting upright position using a controlled 2-second tempo.
- Perform all prescribed repetitions on one side before switching to the other side.
Form checklist
- Keep your chest open and avoid leaning forward or rounding your shoulders.
- Ensure the movement is strictly lateral, as if you are moving between two panes of glass.
- Keep your hips and pelvis stationary; do not let them shift to the opposite side as you bend.
- Avoid pulling on your neck with your hand; the hand should only rest lightly behind the ear.
Pro tips
- Focus on the mind-muscle connection by imagining you are trying to touch your bottom rib to your hip bone.
- Pause for one second at the peak of the contraction to maximize muscle fiber recruitment in the obliques.
Make it harder
- Perform the movement with both hands behind your head to increase the weight of the lever arm.
- Slow the eccentric (upward) phase to 4 seconds to increase time under tension.
