Crunch - Legs On Exercise Ball

What it is

This core strengthening exercise engages your abdominal muscles by elevating your legs on an exercise ball. You will perform a controlled crunch, focusing on pushing your lower back into the floor throughout the movement. This helps to isolate your rectus abdominis effectively.

Technique tips

• Lie with your lower back pressed into the floor.
• Keep your toes touching and pointing inward on the ball.
• Place hands lightly by your head; avoid locking fingers.
• Exhale as you roll shoulders up; inhale returning down.
• Focus on a slow, controlled movement; avoid momentum.
• Your shoulders should lift only about four inches.

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.
