How come when you're exercising (doing aerobics) they keep saying to tighten your abdominals?

Question

What does that do?
What happens if you forget?

Answer 1

Ur abdominals are the core muscles in ur body. they r used in almost every excersise u do in some small way. tightening them gives them and extra workout.


Nothing will happen to u if you dont

Answer 2

Tightening your abdominals helps strengthen your "core" and helps provide balance. The result is better form and a more effective workout. If you forget, it's not the end of the world. You just won't be getting as even of a workout because you're not focusing equally on intrisics and extrinsics. Good luck, and tighten your tush! :-)

Answer 3

Tighten the abdominals helps to avoid injury during exercise. It also speeds toning. If you practice holding your abdominals throughout your daily activities it gently strengthens them and enforces the habit of good posture.

Answer 4

Tightening your abs helps tone your abdominal muscles. It focuses the effect of the exercise into those muscles, enhancing the effect.

Answer 5

It increases your workout as they are your core muscles and also creates a better support for your lower back whilst you are working out.

There should be no major problems if you forget - it just improves your workout if you remember. Once you get used to tightening them during your workout you will find it becomes automatic and you won't forget.

Answer 6

It helps to support your back and keep it in proper alignment. Its natural to forget from time to time. A good instructor will remind the class often throughout the workout to keep abs tightened. Good form is very important to safety. You can hurt yourself if you don't maintain good form.

Here are some thoughts on abs from my 360 Blog of September 10. It describes pulling the abs tightly toward your spine to prevent them from forming bowed out.


There is no site specific way of losing fat... the old myth about working your abs to burn belly fat isn't true. To get rid of love handles, you need to lose overall fat. That happens with exercise and watching your diet. More on that below.

The most effective way to lose fat is aerobic exercise in the "moderate" fat-burning range, ideally first thing in the morning before you eat. When you wake your body is ready to burn fat and your levels of growth hormone are highest at that time. Later in the day it can take up to 30 minutes just to put your body into a fat-burning mode.

Another overlooked way to burn fat is by lifting weights. Skeletal muscle has very high caloric needs... almost twice that of adipose (fat) tissue. Put on a little muscle and you will burn calories all day even at rest. Be aware that skeletal muscle weighs more, so with this approach you may see your weight increasing while your body fat is melting away. Not realizing this often stresses folks who think they should be losing weight as a measure of fitness. Forget the scale, look in the mirror and you will be happy.

To lose a pound of fat, you need to eliminate about 3500 calories. You can do this by burning more with exercise or by modifying your diet to reduce intake. If you do a Google search on say, "swimming calories" you will quickly find a website with tables of calories burned for a given exercise. You can use such lists to estimate how many calories you are burning up with your routine.

For diet, keep a diary for a couple of weeks counting calories, grams of protein, and grams of fat intake. It is easy with online sources of nutritional information (type the name of the food and calories into the Google search engine) and packaging labels. That will let you quickly figure out where the fat is coming from in your diet.

Fat gives you 9 calories per gram. So take the number of grams of fat, multiply by 9, then calculate what percentage the fat calories are of your total daily calories. Restricting the calories from fat to about 20% of your total intake is ideal for a maintenance diet... that isn't overly restrictive. Of note, you need some fat in your diet. For instance, the body uses fat to produce hormones. Once you have a picture of how to modify your diet, you can drop the diary and just go back to it occasionally if you are wanting to tweek things further.

There is a subset of questions that goes further and asks about "How to get a six-pack?" The answer is the same. Six-packs are 20% abdominal exercise and 80% diet. There is one caveat... abdominal muscles will form in the position that you work them, so be certain to pull them tightly toward your spine while doing crunches, etc. Also, during most lifting, the "core is active" which means that you should be stabilizing with contracted abs then too. Fail to do this and the abs will form, but bulging outward and the result is not attractive.

If you are trying to build muscle as a way to lose fat, then you may need to increase total calories and specifically your protein intake. I target about 0.8 g of protein per pound of body weight each day when actively building. That is far more protein than most people need in their diets.
