Setup
- Stand with your feet slightly wider than shoulder-width apart and a soft bend in your knees.
- Extend your arms straight down in front of your torso, clasping your hands together.
- Engage your core and maintain a neutral spine with a very slight hinge at the hips.
How to do it
- Swing both arms to one side in an upward arc, rotating your torso and pivoting on the ball of the opposite foot.
- Exhale forcefully as you reach the peak of the swing, squeezing the glute of the pivoting leg to stabilize the hip.
- Inhale as you swing back through the center with control, using momentum to transition immediately to the opposite side.
- Maintain a fluid, rhythmic tempo, ensuring the movement is driven by the hips and core rather than just the arms.
Form checklist
- Always pivot the trailing foot to prevent torque on the knee joint.
- Keep your gaze following your hands to ensure the neck rotates naturally with the spine.
- Ensure the rotation occurs primarily in the mid-back (thoracic spine) rather than the lower back.
- Keep your arms long but do not lock out the elbows completely.
Pro tips
- Focus on 'pulling' with your obliques to initiate the swing, treating your arms like a pendulum driven by your core.
- At the top of each swing, pause for a fraction of a second to maximize the mind-muscle connection with the glute and oblique.
Make it harder
- Increase the velocity of the swing to challenge your ability to decelerate the movement using your core.
- Hold a light household object or a small weight to increase the centrifugal force and demand on the obliques.
