A split-image thumbnail featuring a fitness instructor on the left with a surprised expression, wearing glasses and a black top, pointing upward with one finger. On the right, bold white text on a red background reads "WHY YOUR AB WORKOUTS" with green text below saying "GIVE YOU LOW BACK & HIP PAIN!" Beneath the text, a smaller photo shows a woman performing a crunch exercise on a mat, with red lightning bolt graphics indicating pain in her lower back and hip area.
