Is Will Bosi the strongest climber? The Results! 

Lattice Team, this is a crazy dream, but it would be absolutely massive if you could get your hands on the Mellow crew.

For the pull-up test, he might not have pulled the hardest but his form was the best out of the people you’ve had on in a while

100% thought Cam was just Pete but with glasses 😂

Meeting and BEATING the averages for 9c and V17 is insane

Would be interesting to see a ranking of all the pros you tested with each exercise.

"I really struggle to fingerboard" - A man with some of the strongest fingers in the world

Would absolutely love to see a graph that compares the results of the really strong climbers you guys have tested, also have you guys ever tried out any core strength metrics or shoulder strength metrics for certain kinds of moves such as gastons or compression? Also was there ever any testing with different edge sizes to see if they results hold up across different hold sizes?

Love watching the dialogue with Will, seems like a really nice guy.

it would be pretty interesting to see a documentary where you share and compare all these numbers and experiences you've had with different top climbers, plus thoughts

Compared to all other elite climbers I’ve seen, he looks so normal! Like is he even ripped? Because if not there’s hope for me still 😅

It would be super duper cool if you did a video tour of the Lattice facility! Seems like not a particularly big space but lots of high impact training apparatus.

Do Yves Gravelle next!!

I honestly thought Will would do much better than he did. Would be interesting to see the entire Mellow crew on here as well as Adam,Alex, Jakob, and a few of the top female climbers as well. Also it would be cool to have a pdf list giving a ranking of all athletes who have done this test just to see how they compare to one another and to see if we can beat their scores(like that’s even possible lol)

I haven't even watched it yet but my guess is "yes, he is"...

All this testing you are doing is amazing! Is there also going to be a video of Adam?

Will Bosi or the so called MR. V17 - the meen of the mean. UNPRECEDENTED - we get hardest boulder stream sessions, then we get standardized testing and metrics in a top level video edit. Cannot believe where is climbing now compared to only 10 years ago. Keep up the amazing work of keeping everyone PSYCHED beyond their mind. Will you are a beast, so well rounded it is bonkers.

These videos are so much fun. But I'm going on strike until you get Seb Bouin in. Need to see his critical force! (Might need to test it for 20 mins with him).

Love the dirty dozen series! Excited to see where Shadowsun lands and if Azrael makes it to the Top 20

Kudos to changing your mind! 🎉

4:18 looks like Hector Salamanca when he's about to blow up the bomb hahaha

Interesting! It would be also cool to see some of the GB competition climbers on this tests 'cause the have a whole different regime and approach to training. Like Max Milne would be perfect!

I have the same hand morphology issues with hangboarding. If I half crimp, my pinky is nowhere near the board and I can only use the Detroit hangboard 😅

yo. Could use a recommendation on how to do a "not so scientific" setup to test pressure on the hangboard. Where can I get the set up you have or could you suggest some DIY setups that one might use for a basement dweller such as myself.

> Hey Will, you just climbed Burden of Dreams 9A. Let´s test your finger strength. < I´m not sure, I haven´t done much finger boarding recently... All of my thoughs to finally start training for climbing: ARE WE A JOKE TO YOU?

Btw that 1 armer on BM 14mm that Cam does on the backround there as he gets introduced..Like since when did shit like that get normal enough that you could no-sell flex with them like that? :D I remember like 5 years ago or smth it was smth that like only Alex Megos could do :D

Have you ever had Yves Gravelle on for this test? The guy seems more of a fingerboarding and strenght athlete than climber, wonder if he could challenge the very top climbers in a test like this :D

Will's psychedness for climbing is why I want to spend all of my time in a climbing gym. Who wouldn't want to be this hyped about climbing :D

Is there a way for people who can’t make it to your facilities or aren’t pro climbers to get help with coaching and performance testing?

Would be interested in knowing thoughts about measuring peak force with a 90 degree arm bend vs straight armed. From the limited testing ive done with athletes it appears that most are able to pull much more when straight armed. Is there value in measuring both?

What is the reason behind Lattice preferring to use 2-rep-max for testing pull-up strength over a 1-rep-max?

PhD in climbing is so cool 🥺

Every time I watch one of these assessments I wonder if the athletes could perform better in the tests if done separately or in different order. E.g. the 2RM pull-up seems to always be performed after being obliterated by the Critical Force test.

Since I am doing research on that broad topic aswell, I would be really interested if there are gender- and/or age-dependent changes in where high-end athletes perform the best? Might be difficult to say though due to the changes between boulderers and climbers?

Nice! I would love to see Yves Gravelle breaking those edges some day!! Really nice content. Thank you :)

Hi Guys for max hangs - is this peak force during 10 second period or average force over 10 second You measure ? Thanks !

Really interesting to see how these metrics change for different types of training cycles. Makes me appreciate the fragile balance that olympic climbers have to maintain to stay at the top. Hopefully lead and bouldering are their own events in the future.

Mean for v17 climbers? I mean, who else do you got? Aidan Roberts?

How tall is Will? I've always thought he looks quite tall, but seems he must be around 175 ish considering how bulk he is and how little he weighs?

11:58 Guys, what is the difference between 3rd and 4th row?

Undefeated and undisputed

"I dropped out of Uni, but not like I went to class for two years and was like oh this is hard and bailed, I went to the first lecture and then quit" lmao

its always fascinating to me how little upper body pull strength is actually involved in climbing, even absolute freaks like will bosi are only doing ~65% bw for 2 reps

When will we get a video of the send???

hes crazy

@Lattice Training - Thanks for the vid! Can you try testing Chris Sharma next? Think we'd all like to see that one day...... #askingforafriend

Was he fresh?? Do you note if there was a rest day(s) before this testing?

Do you do these tests in the same order with everyone? Seems a bit weird to compare someone doing pull ups after critical force to someone who does them fresh?

Please test Ben Moon❤😊

What other V17 climbers have they even tested, hard to really determine if he is average if they have only tested one other

Wasnt there a top for the best results in the tests?? I remember Beto Rocasolano was the top 1 at that moment

Wouldn’t you need to test people a number of times in order to get a true mean of their stats? Single day testing could be skewed based on any number of factors couldn’t it? (How you feel that day, etc….)

I'm pulling 65 kg on the lattice metal block, how does that compare?

How did will do compared to Stefano?

I'm surprised you don't encourage people being tested to scream - it really seemed to make a difference with Emil.

what is Will Bosi weight and height ?

Make the visuals bigger, we can't read them!

Of course he's strong, but technique and intelligence (the mental aspects) are so important in high level climbing as well.

Beard is aid

What's Bosi's Bodyweight?

🏴󠁧󠁢󠁳󠁣󠁴󠁿💪🏻🔥

When Adam Ondra will take the Lattice test??? ;)

Yes he is. Whatever the test says.

so can he do v15s?

I will archive this video for all the people who keep telling me that you can't be strong without looking like a body builder.

wait i can 2 rep pull up more then will bosi? wtf I'm like 5 times worse at finger strength though xD

👍👍👍

arabic threshold?

get seb bouin

Sounds like he generates some upward force in a more unconventional way around 4min 30ish. Hahahaha

So when are we going to see Janja Garnbret do this test? I feel like the worlds strongest climber is a female

"average for a V17 climber" 😅😂

To play a bit of devil's advocate: do we really need another feats of strength video? Are we just all voyeurs now? Is this what gets us psyched, just hours in the gym hanging off an edge? Should it not be doing rad shit at the cliff, having good laughs with friends, and/or giving back to the community? Don't get me wrong. Will is a machine and seemingly a nice human. Let's learn more about the latter and give the training bit a rest. Climbing is (or at least should be) much more than gym training.

DO THEY KNOW HIS FOOT IS ON THE GROUND??? Then the rest of them they aren't even showing a full body shot? I doubt this guy is even a v6 climber.

Not so impressiv He was standing with one foot on the ground and not able to hold the crimp free and a pull up with 40 or 50 kg is doable for an average climber. This strength is far away from Moon or Moffatt, they also had much more tension. This power is enough for V7 and does not explain the V12 or more. Made unfortunatly the experience that climber use an extrem glue while bouldering and climbing.

I'm curious, have you always done the Maximum Voluntary Contraction test before the Rate of Force Development? It was always my understanding that you'll lose your ability to produce power/explosiveness before you lose your top end strength within a single workout, though I don't think it's really been studied. I also wonder if post activation potentiation (PAP) has an effect on the RFD test. Since it has the potential to temporarily increase both RFD and MVC and you take the highest values for both parameters, it seems that the RFD results may be higher than what would be displayed on the wall. This means your MVC reading may be more representative of expected performance, while the RFD would have an acute performance boost from the PAP. Overall PAP needs more thorough and specific research, but I wonder if it could be leveraged by people who are climbing at their limit. The last paragraph of the article below suggests to me that a relatively intense "warm up" could be used to boost performance on at least a few hard sends. bjsm.bmj.com/content/38/4/386
