Jack Arnow - One Arm Chinup Machine

[MUSlC1213]

I thought you were gonna be the one arm chin up machine and I was disappointed

[Turksdahustla]

haha he sounds like mort goldman

[jimmythebastattss]

hey jim thanks to your comment on your website on the way jack grips the bar my strength in one arm negative has improved by at least half thanks

[BeastSkills]

Glad it helped! Jack is extremely strong, in part, because he's extremely technical. You always have to think how you can improve and strengthen the movement.

Nice!! good idea!!!

[BeastSkills]

Around 2/3 bodyweight added seems to be in the ballpark for your first one arm chin-up.

[jockvandam]

That was a great question from Rustynail.

Just to clarify: you reckon that if, for example, someone weighs 100kg, and they can do one chin up with 66kg strapped to them, they will be able to do one one arm-chin. Is that about right?

[BeastSkills]

Just getting the 2/3 weighted chin won't give you a one arm chin-up, but it'll get you much, much closer than anything else I've seen. Several more weeks/months of more focused training and you should have it.

[jockvandam]

Thanks for that. I weigh ~100kg and widegrip pull an extra 25kg for six reps. I'm much stronger doing these than close grip, which I guess is what you need to train. My back is a lot stronger than my biceps. Does this exercise require mostly biceps strength? Thank you.

[asskickerfoo]

No, it's overall body strength and of course your back plays the biggest part in it. Personally I'd leave wide grip alone.

[angrygunsmith]

is 2/3 a one rep max or for like 6 reps?

[PeDoDoKu]

IMO one rep. I weigh 70kgs and could do one rep with 60kg weight. However at that time I was not able to do a OAC. Now I can do one rep with 50kg but have concentrated OAC training to get that skill back, and I´m much more confident with getting OAC again.

[angrygunsmith]

how do you develop that strength in the weighted chinup though becoz ive been trying and trianing it for about a month now and iahvent increased much at all..

[BeastSkills]

It takes a lot longer than a month to build up the strength! Give it time!

[angrygunsmith]

now tha you say it, i did about 3 months before hand, maybe a months break, and now im back again, still ahvent improved much, maybe i just have bad genes, god i wish i could swap genes with someone, all the hardwork i put in and my body doesnt adapt to the trianing...

[rustynail77]

At what percentage of extra bodyweight when weighted chinning, are most people able to do their first one arm chin? Or first one arm controlled negative?
