If you follow the tips we give you here, you can start sculpting your underboob and making it rounder quickly. How to Build Underboob - http://athleanx.com/x/no-more-chest-fat Subscribe to this channel here: / @athleanxespanol As always, we start by doing an honest self-assessment in front of the mirror. Are you dealing purely with chest fat, or are you simply lacking in development and muscle in your underboob? If the former, then you'll need to address your nutrition first and foremost. There is no situation where you're going to fix sagging underboob by simply performing exercises for that area. You have to create a caloric deficit in order to burn fat in your chest and even be able to reveal the degree of development of the pectoral muscles you have now. There are many videos on this channel that show you how to lose fat in general, which will also help you decrease your chest fat levels. That being said, many people not only have problems with chest fat, but poor lower chest development is due to a lack of proper training. They are either not doing the right lower chest exercises or they are doing them incorrectly. That is where I believe we can make the biggest impact. Start by covering your bases with the big exercises. These are the lower chest exercises that you have probably already done but may not be doing exactly right. The decline bench press, dips, and incline push-ups are three of the most basic lower chest exercises you can do. The benefit with them is that you can easily load weight and achieve a bigger chest, but they do not take you through the full range of motion of the pectoralis major. To take advantage of this, you need to understand the science of the pectoralis major muscle. There are three distinct heads to the pectorals. First is the upper or clavicular head which runs from the collarbone down and into the upper arm. The second is the sternal portion of the pectoral which inserts from the sternum and runs back to the common insertion on the arm. Lastly, there is the often overlooked abdominal head of the pectorals. This is the one with insertions on the underside of the sternum and ribs and runs up and into the upper arm once again. The orientation of the chest fibers reveals that to get a better under chest you need to bring your arm not only up and down but also across the entire body. This opens up exercise options such as cable crossovers, push-up variations, and even one-arm exercises performed with bands and a pull-up bar that allow you to get a defined under chest even when you're training at home. The key to getting a sculpted lower chest is to take a smarter approach to your chest routines. This includes making sure you avoid one of the biggest mistakes you can make when training your pecs. This allows your shoulders to sag under the weight of your body or the dumbbells as you perform the exercises. At the bottom, if you sag your body and allow your shoulders to rise during the descent, you will greatly decrease the lower chest's contribution to the exercise. Instead, keep your shoulders down the entire time and press up through your arms and chest on each rep for proper execution. The dumbbell decline bench press should also be performed with your shoulders down and elbows bent. Failing to do so and allowing your shoulders to rise will result in you missing out on recruiting your lower chest. Finally, forgetting about the importance of your upper abs and posture can have a negative visual effect on your pecs, creating a sagging lower chest if this element is ignored. The upper abdomen actually forms a frame for the lower chest line. If you're not training your abs with top-down exercises right now, start. This will go a long way towards creating better visual definition for the lower chest. Likewise, poor posture with rounded shoulders gives you no chance of having an aesthetically pleasing chest. This guide isn't afraid to point this out.
