Hi, I do weightlifting, also called Olympic-style weightlifting, for a living
That sounds really interesting, Lifting weights is something I do when I'm at the gym sometimes, How much can you lift? 
Hi, I do weightlifting in the modern Olympic programme
That sounds great, have you ever won any medals and is Olympic-style weightlifting a competition sport? 
Yes, its a sport which test limit strength and I have won six gold medals in it!
Wow six medals! you must be very good at it, I can usually lift 40 pound dumbbells when I lift. Its tough.
you should try the dynamic and clean technique. It will allow you to lift more! 
Oh ok, I'll look that up. I am always looking for ways to improve, What lifting techniques do you use? any in particular? 
I use the human ballistic limits technique which is kinda advanced and not for beginners
