Setup
- Lie face down on a flat surface with your legs straight and arms extended fully overhead.
- Position your feet hip-width apart and your hands shoulder-width apart, palms facing down.
- Tuck your chin slightly to maintain a neutral spine, keeping your gaze fixed on the floor.
- Engage your core by pulling your navel away from the floor to protect your lower back.
How to do it
- Simultaneously lift your right arm and left leg a few inches off the ground while keeping them perfectly straight.
- Lower the limbs back toward the floor and immediately lift the left arm and right leg to begin the alternating pattern.
- Exhale as you lift each pair of limbs and inhale as you switch, maintaining a steady, rhythmic breathing pattern.
- Move at a controlled, moderate tempo, focusing on fluid transitions rather than jerky movements.
Form checklist
- Keep your hips pressed firmly into the mat to prevent excessive arching of the lower back.
- Maintain straight elbows and knees throughout the entire set.
- Keep your head and neck aligned with your spine; do not look up or strain your neck.
- Focus on reaching long through your fingertips and toes rather than trying to lift as high as possible.
Pro tips
- Squeeze your glutes hard before lifting your legs to ensure the movement comes from the hips rather than the lumbar spine.
- Imagine a glass of water resting on your lower back; keep your torso so stable that not a drop would spill during the alternating movements.
- Depress your shoulder blades toward your back pockets to maximize lat and trapezius engagement.
Make it harder
- Lift your chest and all four limbs slightly off the floor and perform the 'swimming' flutter without letting any limb touch the ground.
- Increase the speed of the flutter while maintaining a completely still and stable torso.
