Setup
- Sit upright on a sturdy chair with your feet flat on the floor, hip-width apart.
- Engage your core and maintain a neutral spine, keeping your chest lifted.
- Rest your hands on your thighs with your palms facing down and elbows slightly bent.
How to do it
- Exhale as you lift your right hand, bending at the elbow to tap your left shoulder.
- Inhale as you slowly lower your hand back to the starting position on your thigh.
- Repeat the movement with your left hand tapping your right shoulder, alternating sides each rep.
- Maintain a controlled 2-1-2 tempo: 2 seconds to lift, 1-second pause at the tap, and 2 seconds to lower.
Form checklist
- Keep your torso completely still; avoid swaying or rotating your hips.
- Ensure your shoulders remain down and away from your ears to avoid neck tension.
- Keep your feet firmly planted to provide a stable base of support.
- Focus on a smooth, fluid motion rather than using momentum to swing the arm.
Pro tips
- Squeeze your bicep at the top of the movement as you tap your shoulder to increase muscle activation.
- Imagine a glass of water sitting on your head that you cannot spill to ensure perfect spinal alignment.
- Slow down the eccentric (lowering) phase to increase the time under tension for the deltoids.
Make it harder
- Hold a light dumbbell or a household object like a water bottle to add resistance.
- Lift one foot slightly off the floor while tapping to further challenge your core stability.
