Decline Crunch

Muscles worked

Main muscles
- Diaphragm
What it is
This core exercise targets your abdominal muscles effectively, performed on a decline bench. You secure your legs and perform a crunch, isolating your entire abdominal wall. Focus on smooth, controlled movement to maximize engagement.
Technique tips
- Place hands lightly by your head; do not interlace fingers.
- Actively press your lower back into the bench throughout the movement.
- Lift your shoulders only a few inches; keep your lower back down.
- Exhale forcefully as you crunch up; inhale slowly on the descent.
- Pause briefly at the top to fully contract your abdominal muscles.
- Focus on a slow, controlled pace; avoid using any momentum.
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.
