I am very lucky because I enjoy my work very much. I'm a fitness instructor at a gym near where I live. I (1) six aerobics (有氧运动) classes a week and also tell my students about (2) and nutrition (营养学). As they say,“You are what you (3) .”
To be honest, I worry about the (4) that many people have today. So many people are overweight. And why? Because they eat the (5) foods and they don't do any exercise. When you work in an office all day, I know it is difficult to find (6) to keep fit, but you (7) need to do 20 minutes a day!
It's also very important to have a (8) diet, starting with breakfast in the morning. It's not a good idea to (9) breakfast although many of us just have a cup of tea or coffee. Eat as much (10) food as possible — lots of fruit and vegetables — and (11) not to eat too much fried food.

I would say we like what our bodies (19) and if you eat more healthy food, over time, you might find yourself wanting to eat them more than anything else. Try it, I think you'll be (20) !
