Setup
- Begin on all fours in a quadruped position on a flat surface or mat.
- Place your wrists directly under your shoulders and your knees directly under your hips.
- Maintain a neutral spine and engage your core by pulling your navel toward your spine.
- Distribute your weight evenly across your hands and knees.
How to do it
- Simultaneously extend your right arm forward and your left leg backward until both are parallel to the floor, exhaling as you reach.
- Hold the peak extension for one second, focusing on creating a straight line from your fingertips to your heel.
- Inhale as you slowly return to the starting position with controlled tempo.
- Repeat the movement on the opposite side (left arm and right leg) and continue alternating sides.
Form checklist
- Keep your hips and shoulders square to the floor throughout the entire movement.
- Avoid arching your lower back or flaring your ribs as you extend your limbs.
- Keep your neck in a neutral position by looking at the floor slightly ahead of your hands.
- Flex your foot (toes toward shin) on the extended leg to better engage the glutes.
Pro tips
- Focus on 'reaching' for opposite walls rather than lifting your limbs high to maximize spinal decompression and core tension.
- Squeeze the glute of the extended leg at the top of the movement to ensure the lift comes from the hip rather than the lower back.
Make it harder
- Add a 'crunch' phase by bringing your elbow and knee together under your torso between extensions without touching the floor.
- Perform the movement from a high plank position or with your knees hovering an inch off the ground to significantly increase the stability demand.
