They are bodybuilders. That's a completely different story.
We're gonna have to agree to disagree here. Machines suck for most things and for most people.
That's a fairly odd statement.
Machines certainly have their place, particularly for individuals who are new to resistance training. If you look at the NASM OPT model, machines have their place when supersetted with more functional exercises that emphasize proprioceptive development.
I do agree that for a couple of the machines listed in the article, the cons do outweigh the pros.
Seated Leg Extension: Also bad because typically most of those machine types brace the thigh just above the knee, which generally causes excessive forces that drive the patella into the joint groove and, over a period of time, can cause cartilage damage.
Behind the knee lat pulldown: Seeing as how I've never seen a machine labeled this way, it's not really the fault of the machine. Lat pulldowns are a perfectly fine exercise, so long as they are done correctly (ie. in front of the body). Pulling the bar down behind the head have no functional use, and prevents the exerciser from utilizing the muscle through its full range of motion.
Seated rotation machine: Outside people with spinal issues, it's a useful machine for individuals that do not have the experience or ability to do more functional exercises. To say that because a resistance machine doesn't "fight fat" renders the machine useless is about the dumbest thing I think I've ever heard in my life.
Pec Deck: Yes it sucks as your primary piece of chest exercise equipment, but it shouldn't be your primary piece of exercise equipment. The machine is useful if it is used as a superset exercise.
Smith Machine: The smith machine isn't any more dangerous than any other machine. Saying it is sounds about as ridiculous as people who claim that squatting is dangerous.
The long and the short here is that the majority of machines aren't dangerous if you use them correctly. Particularly in novice exercisers, machines can help to establish a base of strength, and should be coupled with functional exercises that emphasize joint stability.
Rather than dog on a couple pieces of exercise equipment, Men's Health would have done its readers far greater service by showing them how to use such machines correctly as part of an overall training plan.
