I'm guessing Stu @ BW 62Kg

1 arm + 8kg, 2 arms 140kg

Or something equally hideous

[BicepsMou]

In the 1 arm v 2 arm testing we've done there's quite a lot of variation, but on average 2 arm ~= 1.7 * 1 arm.

Thanks Remus - much appreciated you are sharing this Information from your database!

Oddly good guess Tom, except my body weight is 59kg these days.

+6kg for one arm. 135kg total two arm.

jesus fucking christ

[highrepute]

interesting thread.

My numbers also come out around 1.8. I'm doing from memory and can't quite remember which numbers are for which hold size and I can get at least a plus/minus 2.5kg variation day to day. I'm sure I have a poor one arm score because of weakness in that position. I can lower down on one arm in control from chin to 90degrees at the elbow but below that I just collapse (something to improve)

BW 57, -10 one arm, +30 two arm.

The +6 is fathomable (if not achievable!) but hanging with more than body weight is super impressive/disgusting

+1

I was thinking that probably as the hold gets bigger the discrepancy grows.
At least this is my experience.

Ooooh - interesting

Are you taking the p***?

Adding some extra data as I think i'm an outlier.

I find adding the extra weight way, way easier than 1-arming:

1-arm: 69.5kg (BW-7.5)
2-arm: 144kg (BW+67kg - spread around the body, dipping belt, weight vests & ankle weights)

ratio = 1 to ~2.1

Not at all. It’s a factor that hadn’t entered my mind and no one is citing edge depth they are basing scores on though presumably Remus’s are based on the lattice edge

[Nibile]

 
As I said before, on a 1,5 cm edge my total score would be 67+5+67=139.
On the BM central rung (mine is 20/21 mm) I could add 20 kg RH and 16 LH, so 67+20+67+16=170.
A two armed hang on 1,5 cm with 72 kg added is horrible but feasible, with a good setup.
A two armed hang on 2 cm with 103 kg goes beyond my imagination.

Tested this at the wall tonight and I also seem to have a bilateral surplus. One arm hangs have always felt quite desperate to me, and I feel like I can  try much harder two armed.

+20kg for 5 seconds is impressive!

[Nibile]

Cheers but it wasn't for 5 secs.
It was probably around 2.

Very obvious question, are people posting their "weak" one arm hang score? I suspect not.

I think it's very easy to see how the discrepancy arises, if - like me at the moment - you have significant weakness in one arm/hand.

Putting aside any thoughts about things like shoulder weakness/stability etc:

If L = 65kg (70kg - 5kg); R = 70kg.
Then 2*65/70 = 1.85

(2*65 remains the limiting factor irrespective of additional strength in the other arm.)

Which doesn't seem particularly mysterious.

Add in the factor of the "Y hang", then even less so.

If you have weak shoulders, then I imagine this factor would increase as you sag slightly towards a point loading rather than a "beam".

[bendavison]

Got round to doing this last week and, like a couple others on here, I'm relatively stronger on two arms than one.

On the beastmaker 2000 small edge, 5 second hangs, shoulder engaged, no nestling:
1 arm: bodyweight (82 kg).
2 arm: bodyweight + 85kg.

So a ratio of 2.04 ish.

[abarro81]

+85kg on the 2k edges... mama mia! 

[jwi]

It's best if people compute their “Bilateral Index” as that is the number used in the literature:
BI(%) = 100 *  bilateral / (left side + right side) – 100.
Of course, one arm hangs are not exactly the same exercise as the two arm hang because of shoulder stability issues, slightly different levers etc.

bendavidson has BI(%) =  100*(82+85)/(82 + 82) – 100 = +1.8%, so a bilateral facilitation
Ally Smith has BI(%) = 100*(144)/(69.5 + 69.5) –100 =+ 3.6% bilateral facilitation
highrepute has  BI(%) = 100*87/(2*47)–100= –7.4% so a bilateral deficit
etc...

I think we have rediscovered that:

BLD [bilateral deficit] is actually highly variable among individuals (9). Whereas the BLD most often is observed in acute studies that have used untrained subjects performing novel movements, longer term bilateral training tends to mute the inhibitory effects of the BLD

On the beastmaker 2000 small edge, 5 second hangs, shoulder engaged, no nestling:
2 arm: bodyweight + 85kg.

 

holy fucking shit

how do you distribute so much weight?! 30 kg weight vest and the rest around your waist?

[petejh]

Tried this tonight on a lattice edge.

65kg body weight
1 arm, bodyweight+ 0.5kg (65.5kg total)
2 arm, bodyweight + 52kg (117kg total). Ran out of weights in the boardroom training room but was close to my limit, could maybe have done 54kg


65.5/117 = 1.78

[Duma]

I'm amazed everyone is so even left and right... Or are you all just posting numbers for your strongest arm?

[36chambers]

I'm amazed everyone is so even left and right...

I was thinking the same. Last I checked, I could easily hang 7 kg more on my RH compared to my left.

[joel182]

I'm was equal to within my smallest plate (1.25kg) when doing hangs this afternoon.
