It's been a year, grip nerds. Updated ratings data: https://cannonpowerworks.com/pages/grip-strength-ratings-data No real surprises at this point. Some averages moved by a pound or two.

It's not that I can't buy one but it's always more fun to make.

They say that you have to close your brand new gripper about 30 times to get the spring to it's working condition. Let's try it out.

Carl's GHP10 cert. GHP10 is a pretty hard gripper.

Major update. I was able to speak with the company who provided Warren with the 0.5625" Hercules springs. Warren ordered 100 springs in June of 2012 and then 36 springs in June of 2016. So best case scenario, 136 Hercules grippers is the max. There are likely less that have survived for a multitude of reasons. Whether all made it to production, were damaged in production, subsequently lost, etc. But 136 is the max.

ACE of O-1 Recap We had 21 participants from 6 countries including multiple all-time greats competing in an all 7” O-1 drill rod contest taking place from 1/7/24 to 4/13/24. The difficulties were P Q R 11/32 23/64 with 2 attempts per bar, one point scored for each difficulty bent, and overall time used to break ties! Without further ado… Congratulations to THE ACE of O-1 DEREK GRAYBILL!!! Derek bent all five bars in one session and further strengthens his grasp on GOAT status by dominating the strongest field ever assembled! Alex D and Sergey also bent all 5 bars, coming second and third based on time and each had brilliant competitions as well. Alex D bent all 3 letter bars in cordura singles in a majestic display of power and skill and Sergey dramatically conquered the Final Boss on his second and last try after running out of time with one hit to go on his first attempt. They were the only 3 to successfully bend all 5 bars and deserve to be distinguished with podium finishes! Alex G and Andrey rounded out the Top 5 with four points each after successful 11/32 bends! Thank you to everyone who participated, there was amazing performances throughout the competition! Some that jump to mind are Austin scoring the first point of the contest with a 9 second bend of P and that going wire to wire as the fastest bend of the contest! Robert Miller defeating all 3 letter bends and getting faster as he went while being 36 years older than our youngest competitor Andrey who scored a Top 5 finish at only 21 years old!!! Dmitriy Anisimov reducing his wraps from his first two second P bend and then bending it twice as fast! Juha and Carl-August, one of the all-time greatest Double Overhand and Braced Benders respectively, smashing bends and giving the newer benders a chance to compete against greatness!!! HUGE THANKS to Jan who had an excellent competition as well and without whose help this contest wouldn’t have been anywhere near as awesome! Also Huge Thanks to Todd for judging all my bends, love you dawg! Personal Recap: I almost can’t believe it’s over! All it took was buying the drill rod then cutting, grinding, cleaning, labeling, recruiting, packaging, shipping, judging, updating oh yeah AND BENDING!!!!! Including the most important single bend I’ve ever attempted. This was likely the most competitive lineup ever assembled for a single contest and I was in 8th place with 3 points and out of 23/64 (blue) and only had one 11/32 (green) chance remaining … fortunately Derek spent the week teaching me how to bend and I came through in my last chance to move me all the way from 8th to 4th Place Overall! What a contest if I may say so myself

Here are some infos that I have gathered along with some nice photographs! From right to left we have a Single Stamp, 02' Double Stamp, 04' Double Stamp, 05' Double Stamp and modern design CoCs (with better knurling) from 06', 09' 12' and 14'. There are a total of two missed packages here - the square 02' package where the gripper was placed diagonally, and the early 14' package with the "IronMind" writing much more faded. I had one of those but tossed the package away after some time. The 05' GR8 double stamp was actually opened by me too, something I couldn't resist doing a while back Here are some close-ups of the very old ones: Single Stamp (1995-2002), same package was used on Silver Crush grippers I believe. The very old ones actually said "Silver Crush": A favourite of mine, the 02' Double Stamp, this one particular gripper is also called the "Samuelsson #4" (2002): A slightly different package for double stamps with the CoC writing on the handles from 2004 (the text placement on the back is also very different): The GR8 double stamp package looks quite similar to the white packaging used on the first "modern design" CoCs, but is also slightly different! Obviously, no 1.5 2.5 and 3.5 yet!

Whats your favorite grip feat or what feat do you consider to be the most impressive? I primarily train olympic weightlifting and only started focusing on grip recently, so I really enjoy seeing what's been done in the community. For me it's gotta be Carl Myerscough curling 20kg plates with a pinch grip like they weigh nothing. For no other reason than that's something I walked out into my garage to try and it was so far out of possibilty.

Carl's GHP 10 certification is at the top, for sure. I'd argue that it's one of the greatest strength feats accomplished by a human being period, without hyperbole. I don't think it could possibly be overstated just how difficult it is. People 15 years ago often said that they didn't believe a GHP 10 would ever be closed by a human hand. Carl did it with a 38mm block set.

@Carl Myerscough 's GHP10 is #1 but theres a few other feats that should be mentioned Laine Snook cleaning tbe Inch then doing 300lbs for 10 reps on a rolling thunder Cim Johansson lifting 584lbs on a 2" Axle https://www.instagram.com/reel/C5ixx2BouSt/?igsh=Y3hnMWY3eWduZDF3 @AdamTGlass thumbless Inch Farmers walk for 17.5 feet also, his strict plate curls. @Ben Helms red pill cycle also, highest to clean and press the Inch. @Jedd Johnson 5 tens transfer a few times then fatman, blue and Next Gen Blob lift frenzy

It's not "a" grip feat but I'm not as impressed by any single feat as I am with dominating something like a giant "Medley" that includes a number of what are "stand alone" highly impressive grip feats done non stop in a short time frame. Many include many feats that would be World Class by themselves. I can only imagine the Medley it would take to stop someone like Carl.

My experience is similar. I have run many "grip gauntlet" booths at USAPL meets and had grippers at my desk in corporate America for about 15 years. The average guy, untrained in grip, can close a #1 after they've been shown anything about how to hold the gripper. There was more upside at the powerlifting meets. Sometimes a guy would walk up and no set a #2 and ask "what are these?" That never happened at my desk job. A lot of the powerlifting folks could give the #2 a real scare after being shown how to hold a gripper. There was more downside at the corporate crowd. There would be guys who just couldn't quite get the Trainer even after receiving tips. You could always see the skew was really affecting them from a coordination standpoint and they would predictably exclaim, "it's trying to twist out of my hand!" But, on average, any given untrained guy that tried could usually close the #1.

Week 4 of volume block went well, 2x8 with 174 3.5.

Being a bit sceptical about numbers in training progress (all my grippers are not calibrated), I went for a search for dynamometr and find out that they either expensive or doesnt fit my requirements or just crappy quality. So I took advantage of my jobsite possibilities and combined best of them all imo: durability, price and required dimensions. There are few cons like scales doesnt lock max weight and slippery handles (going to sand blast them). But otherwise works perfect.

Awesome! Was anticipating the yearly update soon. You rated 4,000 new grippers in the past year. Wow, looks like business is booming.

I didn't include Nickel because those vary so much on purpose. But here is some data: The minimum so far is 145 and maximum 169. The average is 153. The most narrow example was 77 mm and the widest was 87 mm. Disgusting. The average spread has been 80 mm.

Got a pair of Jack Lalannes 50lbs bumper plates

I have no idea why my phone made those so huge.

I just did it after some coaching by @smaikelzas. Lets go!

Silver Crush (the full steel goodness)

Not grip related but yesterday I had to help my sister in law move some box’s in her garage . At first she said that it would take about an hour, 6 hours later we were done, in was kind of a workout, picking up box’s and moving them out and moving them back, I did get a couple steps in.

NN 2” deadlift 248.5x2 252.5x2 257x1 and partial Blobtop Left 19.5x1 19.75x1 20x1 20.25x1 20.5x1 Right 16.75x1 17xpartial 17xpartial 16.75x1 17xmiss 16.5x1 16.75x1 17x1 17.25x1 17.5x1 For whatever reason my right hand needs extra time to find its grove.

I started cupping too much and it was messing me up. Lowering weight to focus on form for few weeks. pretty sure the carabiner I was using for a few weeks was making me overcompensate Inch rows left 70x5 69.5x6 69.5x5 right 67.5x6 67.5x5 67x6 inch handle gooseneck holds Left 76.5x10 seconds 77x7 77x6secs Right 76.5x10 seconds 77x7 77x10secs Not greatest workout but decent Gone done helping guy move stuff earlier than l thought. Would have had time to work before going out last night but my work van overheated and broke down on way back yesterday. An hour from home. mechanic told me I blew a hose I told him to mind his business! Waited 2 hours for tow truck and for my dad to get me but it was all worth it for the most amazing ribeye ever last night

The same guy with grippers. Insane!!

Such a cool movie.. still trying to get my dads brother to restore his COE. He doesn’t wanna go crazy, no body work. just sandblast and paint it all black. Been haunting him a lot, I’ll come up on weekends and do all the grunt work.

If you handed someone a gripper who has never trained it and told them to close it they would always attempt to do a TNS with the back handle way down their thumb pad. Most people cant close a #1 first try because they dont know about setting it. Teach people to set a gripper and they smash it. I took my grippers to a weightlifting gym a few years ago and had everyone attempt it. They all failed a coc#1. Then I showed them how to set the gripper, almost all of them closed it immediately afterwards. They all failed on the coc#2 with the closest being a few mm off. Granted the coc#2 they used rates in the 110's (ballpark estimate from how easy my 98 coc#2 feels). If I had handed them an average #2 a few would have closed it. A #2 in my opinion is what I consider average. (100 rgc)

Well my obsessive nature kicked in & I went down a rabbit hole the other night . I ended up ordering a couple variants of chalk. Should get me through for a while

HORN Hit my warm ups at +90, +105, +120/1 BH LH +125/ 4, 2, 1, 1 RH +122.5/ 3, 1, 2, 1 Hands were shot today…nbd I think doing grippers instead of horn a few days ago caused this. Either way, time to keep on going and not let it get to me! Have a wonderful evening

Heavy and Almost Volume Bending Day This was the big setup session for Horrido 6.5” 10.9 cert attempt next Monday, so of course there was a million obstacles, including hardass steel Warmups maybe lacked some pop but nothing to get in a fit over then it was onto 2-3 170mm R O-1 bends and 2-3 170mm Edgins. First R bend went smooth enough although not the smoke show of last weeks somewhat shorter R. But then parent ESP or something must’ve gone off and I went full rush just to the next R, just re-sliding the wraps from the previous bend and taking no rest (at the time I was justifying it that I’ll need to be ready for 5 straight hard minutes against the 6.5” 10.9) … and alas despite the bend going fine enough I was starting to get slowed down by the crush et voilà off goes the baby monitor. I stretched the kiddo a bit, but it was too tough a spot to be able to get it finished before getting him. After a little rest to fetch him, I relocated to the basement gym(I typically bend in the garage) and tried like hell to get that R moving again and finished off. It was a long slow process but eventually the last two cm gave way and I was able to complete the bend and call it the isometrics for the session as well After fighting that battle I didn’t fret about leaving it at 2 R’s and moving onto the 170mm Edgins. I don’t have clamps in the basement gym so I foot rolled three cut Edgins in a row!!! First one felt like air after the R crush, but the by the third one I was getting pretty worn out and got it quite off center, but I had flashbacks to the R crush and in an effort to avoid a repeat I just overpowered the little guy and got it done (if it got properly stuck I’m not sure I had another war in me). Next up (and last up since I counted the second R as an iso finale as well) was barehand 7” C drill rod. But I was unable to muster any power and only had a bit of wobble after two hits so threw on 1/3 imps and took it down while trying to emulate my barehand style. That was a steel bending session!!!!!!!

Here is a front and back picture. Man, I wish I had not gotten rid of this one. Of course this is the case for about every gripper I have ever sold.

Red nail Tomajko style snap, 9 minutes Kerckhaert sx7 #2 Both no leg pad. Great work today, then some time spent with my son (they say he looks just like me)

Good question. Regarding the Powerball 400 "Hulk" gripper. We have rated 100 of them at this time. The average is 195. The minimum is 176 and maximum is 209. We have rated very few of Grip Genie Level 7. Grip Genie has not had a large enough supply yet that they could provide us with very many. However I will say that for the few examples we have rated, they are proving to be harder than the Powerball equivalent on average. They have been 212 average with a minimum of 208 and maximum of 216.

NON-GRIP RELATED Had to wear a suit to work this morning. Apparently I'm getting an award later today. Don't know any more than that...just a crytic email asking me if I was planning on coming in-person and could join a luncheon before the ceremony. Anyway...the REALLY BIG NEWS is my suit pants finally fit again. (Like "legit fit"...not squeeze into them and hope I don't pop a button or split a seam.) Makes me feel like I've finally made some real progress undoing four years of wearing lounge pants and DoorDashing fast food while working from home. Taken some work but feeling pretty good this morning.

RH - grippers 20mm block set - 3x2 Standard Adjustable Ti, RGC 122, 3-sec hold on each rep 10mm (bottom)choked - 3x2 Stainless Adjustable, RGC 156 48.9kg/108lb reverse curls - 6x14 Not hard, but my elbows felt better after. Btw I did this with my custom Inch trainer (grabbing the shaft), so that's why the weight is weird.

GRIPPERS T x 10 BH 1 x 5 BH 1.5 x 1 RH LH 1.5 8 Au 4 1.5 8, 8…I now think it’s time to move up to the Au for rep work here! RH Au 7 IM 2 ALMOST 2…this feels harder than my same rgc 103 rated CU which I’ve repped before…I think 3 or 4 reps here I’ll be close on the hard Pt, and maybe more Au 8, 7 Practice set and 5-second hold LH hard Pt RH GHP 6 Will do Horn on Monday…trying to get my work done and rest a few days before I hit PR sets of 5 in the BP & SQ. Have a wonderful weekend

First tear. Got bit by the GHP 4. Small PR - 122 CoC 2.5, 38mm block set

The first time I bought grippers I bought the CoC 1 and 2. I had read somewhere, most likely here, that most people could start with 1, with 2 as a goal if you've done manual labor. My dad drove me to pick them up at the post office and the both of us could close the 1 and 2 without setting or anything. I have brought a CoC 2 to work and no one so far has been able to close it, did bring a .5 also and all the guys could close that and one 20ish woman

This, nothing else comes even close to this in my opinion.

Chucked these in as I had a massage last night & didn’t want to squat too low but wanted to chuck a bit of weight around. Depth above parallel but not the end of the world. Bulg Squat had me sweating. Knee flexibility is not great but improved as the sets went on. Will add weight as the wks go on. DB Shoulder Press. But light but got shoulders moving. Will add a band in next session. Should give it a bit if extra tension. Inc Bench comfy enough . Felt them tho. Hypers strict really did me. They hit the spot & I really felt them. Good to get them back in rotation. Hub. Well I couldn’t remember where I was with this so hence the loads of sets. Seems to be moving ok. Going to study a few vids tonight on tech. 5 am sess in The Zoo. Got some good graft in & have a few more base numbers to work with. Todays squat set up in The Zoo. You might notice how small English garages are lol.

TNS'd a 165 RGC 3.5 in my 2nd gripper session tonight. The handle mount is horrible.

Plate curls 17.5x8 20x8 20x8 both hands If I can just 8 solid reps on my 20lbs plate I can start adding again... the 10+5+2.5=17.5lbs is the thickest I want to do... 10lbs sledge Curls 11"x5 12"x5 12"x5 Rear Levers 19"x5 20"x5 20"x5 Pronation supination 8"x5 9"x5 8"x5 Weighted ring push ups and ring rows and squats High reps with the Chest Expander Chest Krusher 4 springs Leaving in 1 week. My cousin wants me to drive from Lakeland to Pensacola to see him.. The dude is the man, US Marine Corps flight instructor. I'm just not sure I can handle driving 7 hours with my uncle I'm traveling with. Unless we go with my uncle (his brother) we are visiting. Flying with him is going to be hard enough. I told my aunt and uncle to have alcohol, something to snort, something to smoke and and something to inject when I get there (I'm kidding about everything except the alcohol part)

Half York 90 Dumbbell Hold for Time 04-17-2024 My right hand was done at this point, but my left pushed onward. Just a hold for time with a half York 90 (46.90lb) dumbbell. Musical Inspiration: "Duality" by Slipknot from the album "Vol. 3: (The Subliminal Verses)" released in May 2004.

Oh yeah been married 29 yrs this yr, she’s a lucky lady lol.

4/17 AM WORKOUT DEADLIFT 135 X 5 225 X 5 275 X 5 325 X 5 375 X 2 (wanting to get more) LEG PRESS 100 x 20 200 x 20 300 x 20 400 x 20 450 x 20 LEG CURL 20 x 10 30 x 10 40 x 10 50 x 9 60 x 5 LEG EXTENSION 90 X 15 100 X 15 110 X 15 120 X 15 130 X 15 TWO 4 MNUTE ROUNDS ON THE ROGUE ECHO BIKE

Push Day Kicked it off with bench, worked up to 275x3, 315x2 and 325 2x5 to a 4 board. Then took the workout outside and did some untracked clean and press work with 32kf and 48kg kbs, with the hope they were feeling good enough to go for double 48kg clean and press. But alas they weren’t so it’ll allude me a little longer, it’s only been 12 years so any day now Then I did behind the next presses with 150 pounds for sets of 5/3/3. And 140 pound log viper presses for 3x5. Then wrapped it up with 30 reps of light Viking press and re-wrapped it up with 50 swings of 9kg meel.

Tim Butler is loaning me 168, 172, 175, and 179 3.5s. I bet I can TNS the 172 fresh. This 165 was done at the end of my 2nd gripper session of the day.

Thanks John. Looking forward to it. @matek its a #3.5 This came up on my Facebook memories today 4 years ago.. Want to talk about hard work... Excavated this for a small addition. We bought a mini excavator for this job, couldn't fit anything bigger in the back yard. I wheelbarrowed out 3 dump truck loads full of dirt and and filled a 20 yard dumpster full of dirt to save for backfill, and had to wheelbarrow back in. Lots of jackhammering and drilling to key new foundation into old one. House was built on a spring so I was in constant mucky water which made it 1000x harder.. We ended up doing the concrete footing but the form guy did the foundation. beer tasted awful good afterwork.
