I am pretty toned from exercise, how about you?
I'm not but do you train by increasing weights to increase your muscle force outputs?
I wouldn't say it like that but yes, I do increase weights to train my muscles. I've seen some commercial about training and wondering if it's always been around? I feel like I got motivated by it years back.
I don't know how long but its the current longest running infomercial.
I see, well that's good. Do you know how much it cost to run that?

Response: Ah yes. It is about $1000 per minute to promote infomercial.
