- Rep-based

Setup
- Start in a high plank position with hands shoulder-width apart and feet hip-width apart.
- Push your hips back and up into a Downward-Facing Dog, creating an inverted 'V' shape with your body.
- Lift your right leg straight back and up into a Three-Legged Dog position to begin the first rep.
How to do it
- Exhale as you shift your weight forward into a plank, pulling your lifted knee toward your chest or nose.
- Contract your abs hard at the peak of the movement, rounding your upper back slightly to maximize the crunch.
- Inhale as you push your hips back and return to the Three-Legged Dog position, extending the leg high.
- Complete the set on one side before switching, or alternate legs by returning the foot to the floor between reps.
Form checklist
- Keep your core braced and avoid letting your hips sag below neutral during the plank phase.
- Press firmly through the palms to keep the shoulders active and stable.
- Drive the knee as close to the chest as possible to ensure full abdominal recruitment.
- Maintain a neutral neck, looking toward your hands during the crunch and back toward your feet in Downward Dog.
Pro tips
- Focus on 'protracting' your shoulder blades—pushing the floor away—at the top of the crunch to engage the serratus anterior.
- Slow down the transition from the extension to the crunch to eliminate momentum and force the core to do the work.
Make it harder
- Add a 3-second hold at the peak of the crunch to increase time under tension.
- Rotate the knee toward the opposite elbow during the crunch phase to increase oblique activation.
