Nautilus machines are hands down the best machines ever made, designed by Arthur Jones.
Hammer Strength was done by his son.
I used Hammer Strength in 1990 in the States.
It was okay, some were better than others, but Nautilus was much better in my opinion.
I watched Mike Mentzer use the Nautilus curl machine in Golds Gym Venice, and at that precise moment I realised the mistake people make/made is that they use the same ideas from free weight training...ie a barbell and apply it to the machine.
The reason Nautilus ultimately failed was that they were used incorrectly. The cam design was perfect, sepecially the pullover machine which is still unequalled for hitting a mucle equally over a full range of motion.
As far as sports and real life go, nothing, but nothing compares with the humble barbell. Never will.
But if your goal is to isolate a muscle and train it with equal resistance over the longest possible range of motion, for whatever reason, a BB is a poor choice.
Bands and chains can help dramaticly here, but the Nautilus machine, and to a lesser extent the Hammer Strength equipment are superior for this.
As a side note, in the early 80's there was a Nautilus Gym in Frankston. A close friend trained there from his first ever gym session. He had made nice gains in his muscle size. He asked to train with a group of us at the old Tarzan & Janes.
He nearly fell off the bench press, couldnt squat, basicly had to start again. He had zero real world strength, yet looked pretty good. He never actually got anywhere near any of us in regards to strength, even though he stuck with free weights once he saw how weak he really was.
Would I use machines at PTC?
If I could get my hands on the Nautilus pullover and Bicep curl machines, absolutely, but nothing else really interests me. His crunch machine maybe, I love that thing lol
Another interesting point, Arthur Jones was asked why he never made a calf machine. He said you couldnt design anything more effective than single leg calf raises off a block holding a DB.
Think about that next time your doing fancy **** for calves.
Arthur Jones was also a genius.
