You’re kidding right? Have you ever taken any equipment analysis courses?
Take a look at their 4-bar linkage crunch machine…it has a moving virtual axis that acts the same way the virtual axis does in MOST people performing trunk flexion. It’s an engineering masterpiece as far as gym equipment goes and Tom Purvis is a fucking genius.
Just saying. If you can’t tell me what a cam/moment arm/axis/lever/force angle/pulley is then don’t say anything is shit. You might hate some equipment, but none of it is “shit”, some pretty close…but I can find an efficient use for pretty much anything. LEarn how your body works as a “machine” understand the physics of force application be creative and objective and you’ll find a use…trust me…

LOL I guess I’m studying exercise science and physics for nothing. I’ve used some Nautilus machines two years ago, during a trip to central Florida, due to no access to a barbell and man weight. I assessed it as shit because I found the loading potential when “pushing the weight” to be dangerous.
A lot of shear on the joints and origins/insertions and the apparatuses don’t move in harmony with the body. That may be okay with 40lbs … not so much with 300lbs. My assessment was based solely on that experience. My post was made purely in jest anyways … soooo … PMS on someone else … mmkay? Thanks![/quote]
I believe most things on this site begin in jest haha. If you study physics how can you say you sheared an origin/insertion? [/quote]
I was only referring to joints in that regard. I thought about the origins and insertions afterwards but didn’t acknowledge the verb I had used.

Unless Nautilus comes equipped with scissors… I’m sure you’re aware of the requirements for creating shear, i.e., directions of force and the most important thing contact surfaces. As us physics guys know however force creates wear, can’t do anything about it…and again, since when was 300lbs always 300lbs when you’re moving it…last time I checked it pretty much never is unless you managed to avoid rotatory motion during exercise…Which machine were you using? [/quote]
I was referring more so to where the loading occurs. Like squatting 600 with a close stance vs a wide one. The apparatus forced me into a wider hand placement and a straight bar path which isn’t very comfortable for me. It greatly disturbed my mechanical integrity, but I feel that way about most machines that I’ve tried. I don’t recall the name of the setup. It had a chest/shoulder press station, leg press station, leg extension/curl station, and a low row/pulldown station. They were arrayed in the shape of a square from what I remember. Not sure if they were adjoined or not. Probably not.

I would assess the modern nautilus machines as being a lot more congruent with the movement of MOST people. Hence the reference to the 4-bar linkage and virtual axis movement…did you just disregard that haha?[/quote]
No lol. I make sure to read everything before I post when I intend to make an at least semi-intelligent response. I was focused solely on the reasoning behind my assessment in my previous post.

Just curious have you heard much about RTS? If you’re enrolled in what you say you are i’m sure you would love it. A lot of great minds coming out of that place.[/quote]
No, I haven’t. What is it?[/quote]
