Along with muscles in the lower back, these key abdominals make up your core. Think of your abs muscles as the meat in the middle of a fat sandwich. On top of them is subcutaneous fat, the stuff you can potentially see from the outside, depending on your body composition. Below them is visceral fat , which is the type that takes up residence next to your internal organs—in excessive amounts if you continually overdo it on calories and experience too much pent-up stress.
Visceral fat has been linked to heart disease , type 2 diabetes, and metabolic syndrome, he notes. Since it's nearly impossible to tell by looking how much visceral fat your body is hiding inside, scientists have figured out a couple of DIY guidelines. To avoid increased risk of obesity-related diseases, women should have a waist measurement no bigger than 35 inches measure it at the smallest point of your midsection , and some experts recommend a waist-to-hip ratio of around 0.
According to a Mayo Clinic study , the ratio of waist to hip is believed to be a measurement of visceral fat. Limit trans fats. Step one to combat visceral fat is to toss the trans fats, which used to be found in prepackaged treats under the alias partially hydrogenated oils. These are being phased out and are mostly absent from supermarket shelves now, since scientists discovered how unhealthy they are for your organs, belly fat levels, and beyond.
The World Health Organization is trying to eliminate artificial trans fats worldwide by Seek out more monounsaturated fats—for example, olive oil and those in walnuts and avocados—which help your body metabolize belly fat.
And swig some reduced-fat milk, like 1 percent or skim, while you're at it: Calcium increases the activity of enzymes that break down fat cells and reduces the stress hormone cortisol, which triggers your body to hoard belly fat. Speaking of hormones, is your workout causing high cortisol levels? This is a deep back muscle that runs along the spine. It works together with the transversus abdominis to increase spine stability and protect against back injury or strain during movement or normal posture.
When you decide to add some abdominal exercises to your exercise program, be careful about which ones you choose. A qualified fitness instructor can help you develop a safe, effective program.
If you have a pre-existing injury or medical condition, consult an exercise physiologist or physiotherapist. Incorporate exercises to train your core muscle group, rather than standard crunches that target separate muscles.
Some effective abdominal muscle training methods include:. You can strain your abdominal muscles from overstretching or overuse. Prevention strategies include regular stretching, warming up prior to exercise and cooling down afterwards, and keeping good form while playing sport. This page has been produced in consultation with and approved by:. Acromegaly is caused by an excess of growth hormone in adults, which causes the overgrowth of bones in the face, hands, feet and internal organs.
Exercise can prevent age-related changes to muscles, bones and joints and can reverse these changes too. A person with amyloidosis produces aggregates of insoluble protein that cannot be eliminated from the body. Ankle sprain is a common sports injuries caused by overstretching and tearing the supporting ligaments. Content on this website is provided for information purposes only. Core training is best performed through exercises that emphasize a stable trunk.
Keep in mind, your core should be active with all of your strength training exercises, but it should also be challenged directly. Exercises like planks, bird-dog, dead bugs, pallof press, etc. You could also preferentially target weaker muscle groups of the core to help the entire unit work better together the multifidus is often an area that falls behind.
Abdominal training involves a lot more movement. You are no longer concerned with the group of core muscles working as a unit to create stability. Rather, the goal is to isolate the roles of specific muscles, often for the sole purpose of developing better visual appeal. Only the rectus abdominus and the external obliques need to be considered because the deeper layers are not visible on the surface. The easiest are the muscle fibers of the rectus abdominus which align in a vertical direction and move the lower ribs closer to the pelvis or the other way around.
Common exercises like crunches and sit ups isolate these muscle fibers. Oblique training is a bit more nuanced since these fibers are diagonally oriented. In this article I will tell you what the research has to say!
These three things are foundationally most important and will trump everything else within this article. When most people talk about building their abs, they are talking about their rectus abdominis muscle whether they know it or not! Generally, it stretches from the pubic bone, and stops at the sternum. There are actually quite a few studies showing that you can preferentially engage the lower abs versus the upper abs depending on your exercise choice.
What they have found is generally, exercises with a posterior pelvic tilt think opposite of low back arch provide better lower abs activation when compared to exercises such as a sit up or curl up which provide better upper abs activation. On the other hand though, one well known study by Dr.
According to Dr. Stuart McGill, there were issues with normalization in previous studies stating:. For example, concluding that the lower abdominals have less EMG activity than the upper abdominals when the signals are not normalized may not be due to the ability to preferentially recruit. In his study though, he did find very small differences in upper rectus abdominis activation versus lower rectus abdominis activation.
The difference was so small though that there was no practical value to clinical use. In a separate study conducted by Bret Contreras, he found that you can preferentially activate the lower abs versus the upper abs.
