I started thinking about this as I was grating a carrot and then making dalgona with a regular whisk, both of which I have to take breaks every minute or so because it’s a legit work out. As I do more and more of these kinds of activities countlessly all day long for the last 20 years of my life, how come my hands are relatively in the same shape even though my LH mainly only supports my RH in the most activities?
I also only very recently started weightlifting. So prior to about 2 months ago I wasn’t doing anything that would “even out” the work my LH and RH are doing.
My RH is for sure stronger than my LH because I can’t open a jar with my LH, but how come they look the same if it’s been my RH doing all the heavy lifting my entire life?

Your hands don’t really have very many muscles. Or rather your fingers aren’t actuated by muscles in your hand. Instead they are connected to tendons that connect to muscles in our **forearms**.
[Take a look at this chart.](https://upload.wikimedia.org/wikipedia/commons/d/d1/Musculus_abductor_digiti_minimi_%28Hand%29.png) You can see that within the fingers there are no muscles, just tendons that run across the palm or the back of the hand. In fact you can see this yourself by looking at your palm and inner wrist as you flex your middle finger or ring finger; you should see the tendons moving in your wrist that are pulling your fingers to make them move.
Because of this arrangement someone with strong hands will have more toned **forearms** instead of the hands themselves.
Your other hand still does a lot of things. Whisking requires your other hand to hold the bowl, which is still work, it just doesn’t require fine motor skills like holding the whisk.
Also, whisking is the kind of low intensity repetitive motion that doesn’t build huge muscles. Look at long distance runners. Anything requiring a lot of strength, like moving furniture or weightlifting, will probably need both of your hands.
You will see a difference in tone if you spend a lot of time on an activity that is both high intensity and asymmetrical, like archery or arm wrestling, but most people don’t really have that in their lives.
Mine is. I have a whole body issue with that. My hair is softer and Fuller on one side the other side is thinner and wiry. My right arm is bigger than my left arm. But I also used to do a lot of painting with very large brushes full of a lot of paint. And my right calf is at least a centimeter bigger than my left. To the point where a doctor just lost his mind about it.
Related: I remember hearing years ago that most women have right boobs slightly smaller than left boob; one reason posited is that most people are right handed so it can, in fact, work the chest muscle more which can affect boobiness.
I did an informal poll among my boobed friends and most of us who are right-handed do in fact have a slightly smaller right boob.
Are yours not? My right hand is measurably and visibly stronger than my left
Not JUST from jerkin it ok
When I was smithing my left was stronger than the right- left held the stock, right held the hammer. Stock hand requires more strength
Building visible muscle requires progressive overload which you don’t really have from just repeatedly doing day to day tasks.
Because the average person doesn’t practice hobbies or jobs of high enough intensity where the difference would show. If you did only arm wrestling with one hand, with gruesome training regimens, after some time you could definitely tell the difference
I had a childhood injury that caused me to not have a lot of flexibility in my right hand’s fingers, so I ended up using exclusively my left hand most of my life. And as a result, my right hand is slightly smaller than my left hand: rings that fit on my left index finger are too loose to stay on my right index finger; if I wear a watch on my left wrist, that same watch has to be tightened 2 spaces more if I wear it on my right side
Also there is usually a -small- difference in hand sizes. I used to sell jewelry and rings definitely are a little bigger on people’s dominant hands. Maybe not by much but there is a difference
