Cable Seated Crunch

Muscles worked

Main muscles
- Diaphragm
What it is
This exercise effectively targets your abdominal muscles from a seated position. You'll use a cable machine to perform a controlled crunch, focusing on contracting your core. It's a foundational isolation movement for strengthening your midsection.
Technique tips
- Allow the weight to gently stretch your abdominals at the top.
- Keep your hips stationary throughout the entire movement.
- Drive your elbows towards your hips to engage your core.
- Exhale forcefully as you crunch, then inhale on the return.
- Control the cable as you slowly extend back to the start.
How to track your progress
Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
