Decline Oblique Crunch

A decline bench crunch with rotational movement, targeting the obliques and rectus abdominis through spinal flexion and rotation.
Instructions
- Secure your legs at the end of the decline bench and slowly lay down on the bench.
- Raise your upper body off the bench until your torso is at a 35-45 degree angle from the floor.
- Place one hand beside your head and the other on your thigh. This is your starting position.
- Raise your upper body slowly while turning your torso to the left as you exhale.
- Continue crunching up while rotating until your right elbow approaches your left knee.
- Hold this contracted position for a second, feeling the oblique contraction.
- Lower your body back down to the starting position slowly as you inhale.
- Complete all repetitions on one side, then switch and repeat on the opposite side.
Tips
- Focus on rotating and twisting your torso, not just crunching.
- The decline angle significantly increases the resistance compared to flat crunches.
- Perform the movement slowly and with control to maximize the contraction.
- Keep your abs tight throughout and feel the engagement in your obliques.
