"Revolutionize Your Core with a 7-Minute Ab Workout: No More Crunches!"

Crunches and sit-ups may not be the best exercises for sculpting a strong core due to potential strain on the spine. Fitness professional Elsie recommends a 7-minute, 3-move bodyweight ab workout that targets the rectus abdominis muscles. The workout includes plank reach, plank walk, and plank rotation exercises. Planks are effective for core strength without straining the spine. Modifications can be made for difficulty levels, and building a strong core has benefits beyond aesthetics, including improved support, performance, and injury prevention.
