Crunches are not effective for reducing belly fat as they only work the superficial muscles and do not target the deeper abdominal muscles.
Sit-ups can actually cause more harm than good as they put a lot of strain on the neck and spine.

Incorporate exercises that work multiple muscle groups, such as squats and lunges, to maximize calorie burn and build lean muscle mass.
