"YoYo Technology AB (Inc.) has developed a revolutionary patented strength training system using flywheel(s) - which replaces weight plates and other resistance training devices relying on gravity. YoYo's resistance is provided by spinning flywheels, very much like a child's yoyo, hence the name "YoYo", with the strap being wound and unwound around the axle of a fixed flywheel. A concentric (positive) muscle action overcomes the inertia of the flywheel setting it spinning on low friction bearings, while a subsequent eccentric (negative) muscle action is used to overcome the inertial force of the spinning flywheel."

I'm not really interested in a machine right now, but I can't help but be a little curious about this stuff.  I see nothing in the Spiraflex (system behind Bowflex Revolution) information pertaining to eccentrics and the minimal descriptions provided indicate it uses elastic polymers, not a flywheel.  However, I couldn't find much detail during a quick internet search.

Might be worth a visit to a local retailer this weekend to just try it out.

Wasn't sure. I'm very familar with Tesch's work and his ergometer and knew the Yo-Yo system that Bryan pointed out was based on it but wasn't sure about the Boxflex and didn't take a lot of time investigating it. Good to know

I've done hydraulic resistance machines, rubber band junk, soloflex, and air resistance.
AIN'T NUTHIN' FEELS LIKE STEEL!!!
YOU GOTTA CLANK WHEN YA CRANK!!!

AAAAARRRGHHH! think I'll go eat somethin'...
 
LOL quad! I agree!

Well, the technical way to say it would be &quot;Nothing beats Gravity!&quot; since free-weights are nothing but basic tools for us to resist gravity with our muscles.....just what they were designed to do!
 
Dudes! I'm with you.  However, natural curiosity does occassionally compel me to try and see how this sort of thing works.  

Besides all the arguments about natural plain of motion, etc., my beef with machines is that they are not standardized -- if you go out of town to another gym, who knows how the weight on that contraption compares to the one you have been using.  However, as long as gravity keeps working, 150 lbs of weight is always 150 lbs of weight -- at least on this planet

lol, I'm with Quad

I've got to see or read about other guys who are at least as big as I am using it before I'll try it.   That's the only reason I'm finally getting an incline hammer strength machine.  Read too many good things about them
 
The idea reminds me of that toy we used to make when we were little kids...you'd take a disc and put a couple small holes in the center, put a loop of string thru them and wind it up...and you'd pull the loop ends with the disc in the middle and it would spin one direction, then the other. Has to be something like that principle, only you'd resist it spinning once past the &quot;center&quot; point.

I can't imagine how that thing amused us for very long...
 
Bowflex is using a spring mechanism. The yo-yo uses inertia and momentum of a heavy &quot;iron&quot; flywheel. The resistance is very different as is the speed of movement curve.

You are going to love the machine.

Its great for increasing the load and being safe.

Which is why I love it!

Bryan is a big fan of hammerstrength I believe.

Already have it, and you're right, I love it. I'm a &quot;front delt pusher&quot; when it comes to presses, and I have to work extra hard to stick my chest out and focus so my pecs do the work. I've always been very partial to free weights, but it's much easier to stick those pecs out on this machine than a regular incline bench.
 
Interesting principle, sounds like it could work.

However, I'd still be rather skeptical and I am sure it willnot be cheaply available either.

I'll stick with Peak here, give the pile of iron on the

floor anyday!

They sure don't GIVE this stuff away! Steve, is their isolateral unit the one you use?</div>
Yes, I got the iso lateral wide chest. A World Gym about 60 miles away had the regular iso lateral one and everytime I used it my chest was really sore afterwards and liked the way it worked my pecs. So, I ordered the WIDE one and it's great. I'm not using it right now, but I will after I finish my powerlifting program and go back to bbing for a while. This machine and dumbbell flyes are the only things I can do to make my chest work like I want. Even cable flyes don't do it for me. The inventor of this machine must have had huge boulder shoulders and tiny little bitch tits like me.

I feel the same way. And not without reason, so much of training is psychological. I just love my weights, and the sound they make when I'm loading and unloading the bar. The sight they make when I'm putting up a good amount, etc.
