A short paragraph about the " Increase the Level of Health and Fitness". Please correct my notes.

Skywalker, here's a variant on "not only but also", that you use so well.

You used "not only but also" in this entry before, so what about varying it a little bit?

(original)

Finally, people should not only avoid being inactive, but should also change their work habits, so they can have a balance between their 'leisure time' and working lives.

(alternative)

Finally, as well as avoiding inactivity, people should also change their work habits, so they can achieve/have a balance between their 'leisure time' and working lives.

not only, but also

as well as (something), they/you/I/we/it/--------can/will/should/ought/--------

as well as earning money, people need job satisfaction

as well as helping oneself, one ought to help other

as well as being attractive, he was also intelligent

as well as thinking about it, she was actually planning to do it

as well as buying apples, they bought raisins

as well as robbing me, they also beat me up

as well as making the decision, they actually insitgated............

not only did he speak to her, he met her too!

My own notes

There is not a shadow of a doubt that there are various ways to increase the level of health and fitness in people.

Firstly, exercise is an effective way to 'get in shape'; there is ample evidence that exercise can not only strengthen the immune system, but can also enhance the ability of the cardiovascular system. (Oooh nice use of "not only but also" my 'young Skywalker' hehehe [that's a quote from the film, "Star Wars"])

Secondly, people should control how many (how much food) calories they intake daily, because calorie intake plays a pivotal role in increasing people's weight.

Finally, people should not only avoid being inactive, but should also change their work habits, so they can have a balance between their 'leisure time' and working lives. (I don't like, "sporty lives" it's too informal).

For instance, going for a walk during a lunch break can help employees to 'burn off' some of those stores of fat; a study has shown that taking 30 minute walks over the lunchtime period, three times a week can improve the fitness and well-being of employees who have sedentary jobs.

Brilliant.

Nice one.
(I need to do some exercise though, all I do is sit in front of this PC, make videos, make my site, help people in italki and look on Facebook, whilst eating :)........)
