just a thought but attach two five pound weights on 4+ foot ropes and attach to gear hooks to lower center of gravity. i know its crazy but it might work...

Do you mean while climbing or as some kind of training? How would you deal with the pendulum effect of the weights? On 4' tethers that 10 lbs will develop momentum as it swings around freely, and the ropes wrap around each other, coiling and uncoiling, magnifying the pull of every sideways move you make in unpredictable ways. Why do you want to lower your center of gravity anyway?

the lower your CG is the easier it is to balance

I'm guessing he wants to lower his center of gravity to have better balance.
As was mentionned, the ropes would swing around and make it harder if anything.
Even without swinging, if you start to fall to one side, the weigt is not going to help you whole body align itself back over the line.
for this crazy idea to even partially work , the weight would have to be attached by leg-braces to rigid rods. And I'll just let you think about the complications involved with mounting and walking on a line with such a contraption.

Oh. Okay. I think you'd have the same problem. Inertia is a harsh mistress. Maybe a pair of ankle weights would work for that. Or lead feet.

WOW......I mean dam!........I couldn’t even begin to imagine the amount of grief hanging a bunch of weights off the back of your harness would cause. Come to think of it, I’ve done this. But it was a number 4.5 Camelot that I managed to clean but was unable to remove from the rope. It was on the end of long runner and it swung and smacked me around the knees as I struggled ever upward, cursing my stupidity on choosing to commit so much of my life in the pursuit of an idiotic activity. I recall smacking, scratching, and swearing.....oh, so much swearing.........but I don’t recall it having any positive effect on lowering my centre of gravity.
That is all.

In reply to: i meant for slacklining
if its just keeping your balance you're going for, wouldnt it be easier with the center of mass up high?
maybe you need a lead helmet.

No. Higher center is not the way to go.
The first idea would not work for reasons already stated.
A circus balance pole lowers the center of balance. At twenty feet long and weighing forty pounds, the walker holds it with nearly straight arms and pokes it back and forth to balance. This makes it much easier.
The idea of weight below the line would make it easier BUT the method set forth is horribly flawed. Think about it for a sec. You swing the line, the ropes swing even more. The ropes bump into the line which swings the line even more. With just a little weight that would be really anoying but with a lot of weight...you would have already fallen.
I once saw a BOGUS circus trick that had a girl on a trapeez hanging under a bicycle that is being riden on a highwire by a man. This is not dynamic balance, but counter weight balance.
In my new book "Walk the line, the Art of Balance and craft of slackline" I explain the differents between static, counter-weight and dynamic balance. It might clear things up a little. slackdaddytools.com
The trick to counter weight balance is the ridgidity factor. If you had sholder straps that held horizontal supports that went out perpendicular to the line then had vertical members that were RIDGID, then had them support a platform with weight under the line, you might acheve your desired effect. Even that would have to be ridgidly attached to your body or finnesed to keep from swinging too much. (the trapeez in the circus trick could only swing a little, and only foreward-backward not side to side).
Please share the video when you attempt said feat.

To accomplish what you are desiring, it would be better to strap weights to your calves. This would get rid of everyone's concern about the ropes tangling.

For training purposes (and to just look cool) we clip a 45 pound free weight plate (you know, found in a lifiting room) to the back of our harnesses on a 3 foot sling and do jug laps on our wall.
It really forces you use your feet because your arm's can't hold out long with that kind of extra weight. It's great for strength training and endurance training. Plus when you take the weight off you feel like you could campus anything!
Be careful, though. You're belayer needs to be aware the extra weight will make you harder to hold and you need to be aware the thing will swing around a little.
Keep crankin!

This would not work for reasons already stated. As added notes
1st-the bar used in circus acts is not just for lowering the center of mass, it also increases the moment of inertia. This decreases the "wobble".
2nd-the numbers in your poll are not really meaningful anymore because half the people who logged in failed to see that this was slacklining, and not training.

you could get a sex change-women have a lower center of gravity
(or maybe you could just go part of the way and become an hermaphrodite)
or you could just practice a lot more

does a circus pole lower the CM a relevant amount? dont people hold it at or above their waist? for women, at least, that is probably at or above the CM. i thought it was related to the moment of inertia (correct term?) stated in a previous post.
a lower CM will make it easier to make balance corrections, but a higher CM will make things more stable (assuming the ability to make fine balance changes at the bottom. presumably for the same reason that the horizontal balance pole works for the circus). are you saying that for slacklining, it is more important to be able to make rapid balance changes than to just stay centered in the first place?
not my area of expertise.

NOt sure but,,,,, being weighted down dosent nessisarly help you acheive better balance on the line,, but doing it a whole bunch sure does helps,, and after thinking about it a long heavy pole isnt going to help much either on the slackline,, if anything i think the heavy pole would just hold your body back from getting used to letting the line move under you and allowing your body to adjust to the line rather then adjusting the line to your body,,,,,.... i hope u readers kind of know what the hell im talking about...
(whats that you say,,,, oh yeah,, it really does help to not give up))

If it's slacklining you're doing, might I suggest that you try to walk on the slackline without resorting to some sort of "cheat"? Everyone else does...

I said yes I'd try it but you should have asked if it would work. The answer is obviously no.
