Side Crunch
A weighted core exercise where a dumbbell is held in one hand while the torso flexes laterally, targeting the oblique muscles.
Instructions
- Stand upright with feet hip-width apart and good posture.
- Hold a dumbbell in one hand (typically your right) at your side with arm bent at approximately 90 degrees.
- Maintain a stable stance with your core engaged and knees slightly bent.
- Bend sideways toward the side holding the weight, lowering the dumbbell toward the ground.
- Use your oblique muscles to control the movement; bend slowly and deliberately.
- Continue bending until you reach approximately 45 degrees of lateral flexion.
- Pause briefly at the bottom position, feeling the contraction in your obliques.
- Use your oblique muscles to pull yourself back up to standing position.
Tips
- Keep your torso facing forward; avoid rotating your spine during the movement.
- Maintain control throughout both the descent and ascent phases.
- Do not use momentum; move slowly and deliberately through the full range of motion.
- Breathe steadily; exhale as you bend and inhale as you return to standing.
- Perform all repetitions on one side before switching to the other side.
