Bench Crunch

1. Starting Position: Lie back on a flat bench with your shoulders supported and your feet flat on the ground. Your body should be positioned at an angle with your head and upper back resting on the bench.

2. Hand Placement: Place your hands behind your head, making sure to support your head lightly with your hands. Avoid pulling on your neck to ensure you don't strain it.

3. Engage Core: Tighten your abdominal muscles. This is important for stabilizing your body during the movement.

4. Movement:
- Slowly lift your upper body off the bench by curling your torso towards your knees. Keep your feet flat on the floor and your lower back pressed into the bench.
- Exhale as you lift, focusing on contracting your abdominal muscles.

5. Peak Contraction: At the top of the movement, pause for a moment and squeeze your core muscles to maximize the contraction.

6. Return: Inhale and slowly lower your upper body back down to the starting position under control, ensuring you don’t just drop but maintain tension in your abs.

7. Repetitions: Aim for 10-15 repetitions, rest for a moment, and then repeat for 2-3 sets depending on your fitness level.

8. Tips:
- Keep your movements slow and controlled to avoid momentum taking over.
- Focus on using your core to lift rather than your arms or legs.
- If you feel strain in your neck, adjust your hand position or support your head more lightly.

Remember to maintain proper form throughout the exercise to avoid injury and maximize benefits.
