Most American I saw is fat. I think the Americans need a National Fitness Program like the Russians do. Or like the Koreans and Chinese do. Most Koreans and Chinese I saw is not fat.
It's possible for anyone to take individual action if they really want - but since it's not in the US culture to stay fit, like it's in many parts of Asia, it demands a little bit extra motivation.
The key parts are:
1. Your mind. You must decide that you want a change and you must be commited to a lifestyle change.
2. Nutrition
3. Training
There are lots of guides online, and you could even buy a book like 'body for life' which would give you all you need without you having to do mountains of research.
But for health and fitness like everything else in life, if you are determined to succeed and determined to put in the hard work - you will succeed.
And hard work it is. If you're looking to get anything more than the 'health benefits', it's going to take a lot of dedication and hard work!
Lots of the time it's not going to be fun and/or pleasant.
But life quality will improve, and you will feel better.
Put little effort and commitment in, and you will receive little in return. This is a continuous journey where you will be rewarded for the work put in.
Many people look to get great results from little work - but that never happens. It's like becoming a decent programmer, if you pay others to do your homework, it will simply never happen.
I think the value of hard work and consistent effort and dedication is important to emphasize. Of course old fashioned hard work is not a good sell, that's why supplement companies profit from selling dreams. Take this protein powder, and you'll look like a bodybuilder in no time. Do this sixpack shortcut program and you will have a sixpack in 6 weeks time..
If a chiseled body is desired anybody wanting to do that should know it will take a lot of time and dedication, and it will probably become your number 1 priority in life. Everything you eat, and everything you do matters, to achieve the result you want to have. Doing something 70% is not going to give you any results.
And it's not like saving money in the bank. If you save 100 dollars every week and put in the bank, you will have 400 dollars by the end of every month, and 4800 by the end of the year, and if no further action is taken, those 4800 dollars will just stay there.
If you work hard for a year, you could get a nice sixpack, if that's your desire, it's perfectly doable, unless you're far out fat or in extraordinary horrible shape in which case it might never happen due to excessive skin on your body.
However, once that sixpack is achieved, it will vanish in about a week if you don't keep up the nutritional regime and training. It's not like a thing that you create or buy, and then you have it for ever.
It's a lifestyle, and it's hard - and that's why you see so few people in good shape. And it's not only about going to the gym, but also grocery shopping, preparing all the meals, and eating all the meals - actually professional fitness models have it as their full time job.
In addition most fitness models and bodybuilders you see, and want to be like, are chemically enhanced, often sacrificing their health in the process. So while they look healthy on the outside like a super hero, they might not be so healthy inside. Heart attacks and other health issues are not unheard of.
So the most sensible way to go about it, is to determine what kind of level you want to put it on, and what's important for you. If you eat relatively healthy and go to the gym for good workouts 3 times a week, that's enough to keep you in pretty decent shape. But remember moving the body outside the gym and work, like walking is important too.
Anyone very interested in the topic should join some training community online.
The stubborn body fat is also the part that goes last. These are the reserves nature has put on your body for hard times, and to have it go away, you need to use up all other reserves first.
So the answer to have it removed is to keep up very vigorous exercise and a good healthy diet regime. Of course there's shortcuts here as well, where you can take fat burners (I'm sure some steroid forum could help you out), and you can eat virtually anything and get that sixpack you crave, but if you think of it long term, it's a bit like adding some suspicious agent to the gasoline of your car, it might go better and faster for a while, but eventually things will clog up, and you will run into problems, and in difference to the car, the body cannot simply be fixed unless you have shitloads of money and access to the best healthcare, and even then there's no guarantees, if you run your body too hard for long enough, it will give you trouble.
So stay healthy, go the old fashioned route, and enjoy all the benefits it will provide for you in your life.
