Video Instructions on How to Do Crunches
Crunch Exercise:
Muscles Targeted:
- Primary: Rectus abdominis (the six-pack muscles)
- Secondary: Obliques (side muscles) to some extent
Instructions:
- Starting Position:
- Lie down on your back on a mat or a comfortable surface.
- Bend your knees, keeping your feet flat on the ground.
- Place your hands behind your head, lightly supporting your neck. Avoid pulling your head forward with your hands.
- Body Alignment:
- Keep your back in a neutral position, meaning it should be neither arched nor pressed flat against the floor.
- Execution:
- Inhale and engage your core muscles.
- Exhale as you lift your upper body off the floor, aiming to bring your shoulder blades a few inches off the ground.
- Focus on using your abdominal muscles to lift, rather than straining your neck or using momentum.
- Contraction:
- Hold the contracted position for a moment, squeezing your abdominal muscles.
- Lowering Phase:
- Inhale and slowly lower your upper body back to the starting position, controlling the descent to work the muscles throughout the entire range of motion.
- Repetition:
- Perform the exercise for the recommended number of repetitions. Start with a manageable number and gradually increase as your strength improves.
Tips:
- Maintain a steady and controlled pace throughout the exercise.
- Avoid pulling on your neck or using your hands to lift your head. Your hands are there for support, not to assist in the movement.
- Focus on the quality of the movement rather than the quantity of repetitions.
Common Mistakes to Avoid:
- Jerking your neck or using your hands to pull your head forward.
- Lifting your entire back off the ground, which can strain the lower back.
- Holding your breath—remember to breathe throughout the exercise.
Variations:
- There are many crunch variations, such as reverse crunches, bicycle crunches, and oblique crunches, which target different areas of the abdominal muscles.
Note:
- Consult with a fitness professional or healthcare provider before starting any new exercise program, especially if you have pre-existing health conditions or concerns.
Remember to listen to your body, and if you experience pain (other than the normal muscle fatigue), it’s advisable to stop and consult with a fitness professional or healthcare provider.
