what's the deal with the damper control (i think that's what it is) on the machine? i've adjusted it to different settings and can't really tell any difference.

does anyone know what this does and where it should be set at?

Sounds like it is broken! It should make the resistance increase or decrease.

huh, there are actually two of them at my gym, so i'll check out the other one. it's been at 9 on the one i've been using. what setting do you all recomend setting it at?

It doesn't make a huge difference either way. At CrossFit, they usually have it at 3 I believe.

Actually it can make considerable difference, although its use and effect is often misunderstood.

In brief, it controls the amount of air resistance into the turbine, against which one pulls. The higher the number, the greater the amount of air, the heavier the drag. The difference is akin to rowing a heavier versus a lighter boat. Misunderstanding typically comes from a too-literal equating of this to lifting with more or less weight. I.e., one who lifts one hundred pounds ten times is exterting more than if he lifts fifty pounds ten times. This is not necessarily analogous to drag factor, however. One can exert just as much pulling on a low drag factor as on a higher. To a degree, it is like switching gears biking. But there is yet another factor, which is that, since actions have equal and opposite reactions, resistance increases with the effort the rower applies. This sounds, perhaps, magical, but it is simple physics. Think of a boat. If one pulls an oar gently, it passes easily through the water. If one pulls hard, however, the oar doesn't fly through the water; rather one feels resistance equal to the force applied. So with the Concept 2.

A beginner will probably find that the higher drag factor results in a lower stroke rate and will tax the skeletal muscles more; the lower drag factor will cause an increase in stroke rate and less skeletal muscle fatigue. But with improved technigue this will cease necessarily to be the case.

I hope this helps.

I guess what I meant was that it hasn't made a big difference in my times. It does feel different however.

thanks for the info! i was supposed to check it out today but forgot after doing thursday's WOD. never done power cleans before and they really kicked my ***! i'll check it out tomorrow!
