I'm a Trainer, and This Is the Ab Workout I Do For a 6-Pack

If you want to get stronger, more defined abs, there are a few things I recommend you do. My first suggestion is to look at what you're eating. Are you consuming lots of foods that are processed, are high in sugar, and have zero nutritional value? If so, you're going to need to revamp your diet and eat a healthy balance of carbs, protein, and fats. Second, I recommend implementing a calorie deficit. This is not the same as starvation; it's simply eating fewer calories than you burn each day in order to lean out.

Finally, to boost your metabolism and burn more fat, begin to implement high-intensity workouts like sprinting into your routine, along with heavy compound exercises (exercises that work multiple muscle groups at once), such as squats, deadlifts, rows, and lunges while strength training.
