Performing the: A Step-by-Step Tutorial Weighted Crunch
Hold a weight plate or dumbbell across your chest with both hands.
Exhale and slowly curl your upper body, lifting your shoulders and upper back off the floor while keeping your lower back pressed firmly against the mat.
Hold the crunch position for a moment, focusing on contracting your abdominal muscles.
Slowly lower yourself back down to the starting position while inhaling, ensuring the movement is controlled and not letting your shoulders fully rest on the floor before starting the next repetition.
