Based on the limited reference provided, the oblique crunch targets the oblique muscles. Here's a general understanding of how to perform an oblique crunch:
-
Starting Position: Lie on your back with your knees bent and feet flat on the floor. You can place your hands behind your head, but avoid pulling on your neck.
-
The Crunch: Engage your abdominal muscles and lift your shoulder blades off the floor.
-
The Twist (Oblique Focus): As you crunch up, twist your torso, bringing your elbow towards the opposite knee. Focus on contracting your oblique muscles. Avoid using momentum; the movement should be controlled.
-
Lower Back Down: Slowly lower yourself back down to the starting position, maintaining control.
-
Repeat: Repeat the movement for the desired number of repetitions, then switch sides to work the opposite obliques.
Key Considerations:
- Proper Form: Focus on controlled movements and proper form to avoid injury.
- Engage Core: Make sure to engage your core muscles throughout the entire exercise.
- Avoid Neck Strain: Don't pull on your neck with your hands. Let your abdominal muscles do the work.
- Breathing: Exhale as you crunch up and inhale as you lower back down.
