Wrist Size as a Predictor of Bicep Potential

I’ve noticed my wrists have gotten bigger as I’ve gotten stronger. I’ve heard other lifters say this too. This isn’t fat I don’t think. I and the other guy I’ve talked to about this are both fairly lean. This isn’t huge growth, but somewhere around 1/4". I used to be able to touch my thumb and middle finger, and I can’t anymore.

I think there is some muscle in the wrist that can experience hypertrophy.

I am assuming the calculator is based on wrist size being static.

Either way, most really good BBers have small joints. They don’t have the 14" arms that the calculator says they should have.

reasonable expectation? Here you go. MORE mass than you have now.
Do the work. Brief, frequent, intense.

To this point, I recently encountered a study that showed climbers’ finger bones actually grew thicker after so many years of climbing.

Is there an Index Finger to Muscle Mass ratio I could reference so I’ll know how big I can get?

Clearly it’s a moving target. Your bodybuilding genetic ceiling with which you are born increases as you spend time climbing rocks; that’s simple math.

Look man, I just want to know if I’ll be good at something before I do it.

Is that so much to ask?

I’ll add to the skinny guy stuff. 6 footish, 160-something lbs in the first pic


208(ish?) in this one

Try very hard at eating and lifting for a few years and you’ll be amazed at what you can do. Stop letting goofy stuff hold you back from actually doing something productive and getting closer to your goals.

Edit to add that I do not claim to have “good” biceps currently, but I’m assuming I’ve added a substantial amount of meat to them. I also find it strange that you are focusing on biceps when it’d look pretty crazy to have fulfilled your potential on biceps and not anything else. Train it all dude.

Damn brother, I’ve never actually seen you throw up the before and after like that. Nice work

Thanks dude, I appreciate that. I’m content with what I’ve been able to do in the past 4-5 years considering my starting age and lifestyle, haha. I’m just happy to not be a complete turd anymore.

Its good seeing some before and afters :+1:

I would have loved to have some of the starting points some of you fuckers had.

In case anyone has forgotten, or hasn’t seen this, this was me at 18.

Aside from the fact that I used a ‘Casey Butt wrist calculator’ thing, plugged in the OP’s numbers and got different results, it’s still horse shit, even at the numbers it spit out for me. I exceeded what the calculator told me my potential was, and I can goddamn guarantee I didn’t reach my own actual potential, as I spent VERY little time actually training my biceps, and I never got my bodyweight over 210ish lbs.

You were about the size of what I ate for breakfast at the age of 18….
Great transformation.

Thanks! I would say this is, more or less, my best look over the last few years. Good combo of size and leanness.

I just measured my wrist, and it’s maybe 6.25" . My biceps in this picture were probably just under 18" (this is just a guess, but I know that’s approximately right).

We can trade wrists OP. Mine are 7 inches and its a mild hassle getting custom sized bangle/bracelets.

If you hit your wrists enough with a sledge hammer so they break then heal and repeat the process several times, they should end up bigger than what they originally were due to excessive calcification and metal pins holding them together. This is the only way I can see to get your biceps bigger.
The only downside is that you won’t be able to use your arms as you go through months or years of surgery to pin the shattered bone back together. You also probably will never lift a weight again but your genetic potential should have increased.
Problem solved.

Well, as long as I bet them bigger somehow…

I had 6 inch wrist and did wrist curls and reverse wrist curls to build up the small muscle in the wrist and now they are 7 inches and my flexed biceps is up to 17 inches. I always had a small frame but with patience and diligence my 35 inch chest is now 40” and my arms went from 13 to 17” . Build your triceps up because they are 2/3 of your arm circumference

I don’t know if this is you, but in other forums guys would ask for an ideal routine, and as the pros and cons of various regimens were debated, the OP would do NOTHING. No bodybuilder routine, no bro-split, no Starting Strength…NOTHING. Doing nearly anything, and putting their heart into it, would at least have primed the pump for the eventual “good” routine they’d adopt. Remember, “A good routine consistently worked hard will supersede the perfect routine not followed.”

So, what routine are you on, and what past routines have worked (or not worked) such that you’re worried about your genetic limitation? Even if you believe that calculator (I don’t), you’ve got several inches to add.
