Why do all physical skills assume your writing hand is best as dominant?

[hawkal]

I write with my left hand and because of that everything that I do that could be influenced by hand use I'm instructed to use my left hand even though it may feel completely unnatural and awkward to me. I play guitar right handed, I use my right hand in all sports, and I fight right hand dominant but when someone asks me if I'm left or right handed, or what hand I write with suddenly I'm doing it all wrong even though it feels totally natural to me.

How does the hand you write with effect your ability to punch using that hand or to strum a guitar with that hand? It seems absurd to me

Is there any proof that writing hand dominance is better in all skills?

Never heard of this one. The only handed thing I have heard is that for most people the right hand is better at ‘sending’ type activities and the left at receiving (sensing).

I highly suggest whatever feels more natural.

My writing hand is definitely dominant (right hand).

The interesting thing is that it appears it's not only that I punch stronger with my right hand, I also kick better with my right leg. My jumping leg is the left leg though.

I think that it's quite common that people find it easier to punch with their writing hand. It might be because the co-ordination of writing hand is usually better, since you use it way more often. This co-ordination makes the punch stronger.

P.S. Why care what's right and what's wrong, if you find that although you write with a left hand, your right hand is dominant, so use it (or work more on the right hand so you'd increase ambidexterity).

I write with my left hand, but do all sports with my R, except baseball and golfing.

I think the main issue is that people are ac costumed to teaching the right hand, so you learn skills through that when you're younger. My fighting stances are R hand dominant because that's how they were taught. I can change between the two, and do, but as I grew in skill, I noticed that I definitely preferred the R because I practiced it more.

Im left handed & i too do everything else with my right.

Yeah, its a strange thing. I'm left handed but when it comes to knowing which is my better kicking leg or which arm I punch best with, there are all these trade offs.

I have more power in my right cross but my left has more control in my hooks. Also, I can keep my balance better when doing one legged kicks that are thrusting out(side kicks, back kicks, hook and spins) with my left leg, and anything with insteps turning to the head are best executed with right.

I guess that just because one side has more power, it isn't necessarily the dominant in skill. As said before, it depends on how you were to develop a skill.

At least we're not forbidden to write with the left like in previous centuries.
