If you want a strong core, you have to work all your core muscles. That’s why transverse abdominis exercises are so important, since lots of people tend to forget about those deep core muscles when focusing on their abs. Even though there are a ton of great abs exercises out there, many tend to favor your rectus abdominis (the muscles running vertically on the front of your abdomen) or your obliques (which run along the sides of your abdomen). But focusing on your transverse abdominis—located beneath your obliques—can help you build well-balanced core strength.
