Here is how I'd change it:
If we want to be healthy, we must exercise, sleep well, and eat healthy food.
Walking and Tai Chi are two forms of exercise that most anyone can do. Tai Chi is good for our health and promotes blood circulation.
Karate and Taekwon-do keep us fit and are also useful for self-defense. Dancing is good exercise and also promotes gracefulness. Jogging is good for improving stamina and strengthening the body. Swimming is low-impact, yet every muscle of our body is exercised.
[there should be something about sleeping well here]
We must have a balanced diet. For protein, we must eat fish and meat. Rice, fruit and vegetables are rich in carbohydrates.
There are other ways to get protein, too, but I left that alone.
While your first sentence is grammatically correct, I changed the wording to eliminate any possible misunderstanding about whether we should eat healthy exercise...
"Strolling" is a bit obscure -- I changed it to "walking."
Removed the line about younger/ elderly -- depending on your definition of "elderly" (over 55?), lots of "elderly" people can and DO jog. That sentence also just seemed extraneous.
"Overstrain" was awkward, I replaced that section with "low-impact."
Let me know if you have other questions.
Stumble It!
