Setup
- Lie flat on your back on a mat with your legs fully extended.
- Place your arms by your sides or slightly overhead for a greater challenge.
- Engage your core by pulling your navel toward your spine and pressing your lower back firmly into the floor.
How to do it
- Exhale as you lift one leg toward the ceiling while simultaneously reaching the opposite hand toward that foot, lifting your shoulder blade off the mat.
- Inhale as you slowly lower both the leg and arm back to the starting position with a controlled 2-second tempo.
- Repeat the movement on the opposite side, alternating legs and arms for each repetition.
- Maintain a steady rhythm, ensuring your lower back never arches away from the floor.
Form checklist
- Keep your lower back glued to the mat throughout the entire range of motion.
- Ensure the leg remains as straight as possible to maximize quadriceps and hip flexor engagement.
- Lift your shoulder blade completely off the floor during the reach to engage the obliques.
- Avoid using momentum or swinging the leg; move with deliberate control.
Pro tips
- Focus on 'crunching' your ribs toward your hips as you reach for your toe to maximize upper and lower abdominal compression.
- Pause for a split second at the peak of the movement to emphasize the contraction of the rectus abdominis.
Make it harder
- Keep both legs hovering 2-3 inches off the ground throughout the entire set instead of resting the non-working leg on the floor.
- Hold a light dumbbell or medicine ball in your reaching hand to increase the resistance on the core.
