Common Mistakes
- ! Moving too quickly: Focus on the quality of the movement rather than speed to achieve maximum benefits.

Introduction
The Dumbbell Single-Arm Starfish Crunch is a dynamic exercise that targets your core while also promoting stability and coordination. This exercise combines the benefits of a traditional crunch with a unilateral arm movement, training not only your abdominal muscles but also your shoulders and arms.
Main Muscles
This exercise primarily targets the rectus abdominis (the abdominal muscles) and the obliques (side muscles). The deltoids (shoulders), triceps, and, to a lesser extent, the hip flexors and lower back muscles are also trained.
Possible Alternatives
- For a less intense variation, perform the exercise without dumbbells.
- To increase the intensity, use a heavier dumbbell or perform the movement more slowly.
- Alternatively, you can perform the Starfish Crunch without the arm movement to focus more on your core.
