I don't know how long but its the current longest running infomercial.
I've seen that infomercial on tv for years now.
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.
It is the longest running infomercial product at this time.
