Reverse Crunch

Muscles worked

Main muscles
- Diaphragm
What it is
This core exercise effectively targets your abdominal muscles, focusing on the lower region. It involves lifting your lower body and curling your pelvis off the floor to engage these muscles. You will feel a strong contraction in your rectus abdominis as you bring your knees towards your chest.
Technique tips
- Keep your arms flat on the floor for stability.
- Initiate the movement by rolling your pelvis, not just swinging your legs.
- Exhale slowly as you lower your legs back to the start.
- Focus on controlled movement, avoiding momentum.
- Ensure your lower back remains pressed to the mat.
- Bring your knees towards your chest at the top of the crunch.
How to track your progress
Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
