Amit_S hit the nail right on the head with the saying that people want a quick fix.
Thing is, machines are EASY. It's not hard work. (Most) People don't want to work HARD to loose that fat, gain that lean muscle or get faster, or whatever. They want it the easy way. Machines deliver an easy way to exercise. Even when it doesn't produce results, people will make up excuses and still continue using them.
Also, ignorance may play a good part in this. |
