response: I'm afraid I have no idea how long but its the current longest running infomercial.
original_response: I've seen that infomercial on tv for years now.
history: 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.
knowledge: It is the longest running infomercial product at this time.
