Name of Exercise
Type of Exercise —Multi-joint
Muscles used —Abdominal muscles
As a beginner, it is important to perform a posterior pelvic tilt prior to performing the crunch. To do this, press your lower back into the floor while curling your pelvis slightly upward. This will help you engage the right muscles.
There are a few modifications that can make the exercise more challenging:
Avoid pulling up or jerking on your head with your hands. This could cause injury to the neck. Keep your hands light on your head and concentrate on using your abdominal muscles to do the crunch. Make sure to maintain correct technique even as you fatigue.
