Step by step instructions, muscle activation and variants for the Dumbbell Starfish Crunch.
The dumbbell starfish crunch is a beginner-friendly ab exercise performed lying on the floor with arms and legs spread wide in a star shape. Holding a dumbbell adds resistance to the crunch, increasing engagement of the rectus abdominis.
The Dumbbell Starfish Crunch is a foundational movement that builds strength and muscle through controlled, progressive overload. Train it 1 to 2 times per week with 3 to 5 working sets per session, gradually adding weight or reps as form holds up.
