Whilst there are many different targets in fitness, many people go to the gym with the goal of looking better in mind. Whilst with most muscle groups people want to make them bigger to look better, so they train them with heavy weights and/ or high reps to push them to grow. With abs however, this will not be the best goal. Training the abs with heavy to get them bigger may actually detract form your overall shape by making your waist look thicker.
So when training abs, we always recommend avoiding heavy weight, so that they can be trained whilst keeping your midsection small. Any ab exercise that makes your stomach protrude out should be avoid, so exercises with your feet hooked under a bar, or with a weight should be kept to a minimum when training your abs for appearance. By keeping to crunches or vacuums it will allow you to work your abs but also avoid your core becoming thicker.
To perform vacuums, blow all the air out of your stomach, then suck it in and hold for 10 seconds.
