Even if summer is over, working on your body is always important. Losing inches and having your six-pack visible are the most popular goals for the abdomen exercises.
It is the responsibility of the rectus abdominal muscle to flex the lumbar spine and it plays an important role in breathing. This muscle can be viewed as a 4, 6, 8, or even 10 pack sometimes from the outside.
The good news is that there is a big variety of different ab exercises that will help you achieve this goal if you are looking to train your ab.
Even if you didn't focus on them, the compound exercises will hit both of your upper and lower abs parts.
Any exercise where you need to keep your body solid and strong, such as static grips such as the plank and Romanian one-leg deadlift, is also key to your core.
