I really need to lose some weight. I should go on a diet.
I think you should work out more too.
Wow! You are much skinnier since the last time I saw you.
I have lost about five kilos.
How did you do it?
I was on a diet and exercised daily.
I hate working out.
You can try a low-impact workout schedule. Why don't you go to a gym?
Good idea. Then the trainer will help me to make a fitness plan. Besides that, what's your secret?
The secret is persistence.
