This means the internal oblique is a same side rotation muscle whereas the external oblique is an opposite side rotation muscle. When rotating to the right, your left external oblique is working with your right internal oblique. They take on the same responsibilities as your external obliques. However, the muscle fibers run in opposite directions of the external obliques. But, t hat doesn’t mean they are not equally as important. It is a deep muscle that can't be seen, no matter how low your body fat percentage is. The internal obliques are located beneath the external obliques, running along the sides of the rectus abdominis as well. Moreover, it assists and contracting the abdomen and keeping your guts in place, nice and safe.

Its main job is to twisting and bending your the body side to side, and to also resist twisting and bending - so, trunk rotation, anti-rotation, lateral flexion, and anti-lateral flexion. It is also a superficial muscle, but it's going to take quite a low body fat percentage for them to be noticeable, even if they are well-developed. The external obliques run along the sides of the rectus abdominis from the ribs to the pelvis. A bulletproof core starts with the transverse abdominis. planks, crunches, rotational exercises, etc.). Think of this as your deep stabilizer muscle and protector of your guts! It plays an important role in many exercises because of this (i.e. Moreover, it plays a big role in spinal and pelvis stability. It plays the very important role of abdominal compression, which means drawing your belly button toward your spine, as well as protecting your internal organs by keeping them in place.

The muscle is divided into two halves (left and right side) by a band of connective tissue known as the linea alba. 8 pack, the muscle is long, extending from your sternum to the bottom of your pelvis. Now, regardless of whether you have 4 pack abs vs.

Needless to say, it is a superficial muscle, meaning it is close to the skin, so it is visible with low body fat. The rectus abdominis is your 'six pack' (or 2, 4, 8, or even 10 pack depending on your ab structure, as everyone is different). When you think of 'abs', this is the muscle.

That way you will understand which muscles are being worked with all the various cable core exercises below.** On that note, let's look at each muscle and what their main responsibilities are. After all, there is no point in putting up walls without a strong pillar to hold them up. So, w hile the stars of the show are the rectus abdominis (your 'packs') and the obliques, because they are visible (if you have lower body fat), it is paramount that you work your core from the inside out, meaning that you train your core through all planes of motion and actions. Transverse Abdominis (abdominal muscle)Īmong those, the transverse abdominis, internal obliques and multifidus are deep muscles that rest beneath the others.Your core consists of muscles that cover the front, sides and back of your mid-section (abdomen and low back). Six major muscles make up your core, and they aren't only your abdominal muscles. The abs and core, in particular, benefit from its use in that it's a great way to progressively increase strength and add variety to your training (through all planes of motion). Keep on reading for 17 of the best cable ab & oblique exercises that will take your core workouts to the next level. The nature of the cable machine allows for fluid motions and consistent tension, which lets you more efficiently strengthen your muscle group of choice and increase time under tension. While most use it for upper body exercises, such as the chest, back, and shoulders, not many realize it is quite effective for the abs as well. The cable machine is perhaps one of the most versatile and user-friendly machines you could use in the gym.
