Vacuum Abdomen is a free Android app developed by SportsHealth Apps that centers around the famous "vacuum" exercise. This exercise targets the internal muscles of the abdomen, which can help reduce protruding or sagging belly, and give you a slimmer waist.

One of the conveniences of the app is that the exercise can be performed lying down, standing up, or sitting, making it easy to do anywhere. If you want to strengthen your core and achieve a better-looking physique, Vacuum Abdomen is the app for you.
