How do you roll your ''r'' in Spanish? What do you do?
15 Answers
Here is what I did. I practiced "Trrres trriste tigrres trragaban trrigo en un trrigal until my tongue hurrrt. It worked (along with the GOYO method.
Popl- you're a guy. You already know how to roll your Rs. Seriously!
I know you played "machine guns" when you were a kid. That noise you made with your tongue on the roof of your mouth just behind your teeth? That's the rolling R sound.
Some of us also used the same sound for trucks or bulldozers.
If you're a guy- you probably did it. If you're a girl- sorry, can't help you! 
Stuff about Rolling RRs
Lazarus explains how to make the RR sound.
For some reason, webdunce explains RR again.
Most important thing, it is all about the tongue's tip resisting air flow and a balancing of those two opposing forces resulting in the vibration of the tongue's tip. There is no way a person can move their tongue fast enough by way of muscular up-and-down movements. I feel most people who struggle with this sound are trying to move their tongue fast enough some kind of way, which not even the most gifted Spaniard can do.
Cheers.
I came across this video the other day and thought it might be useful. One of her examples is to say in English, 'put it on' faster and faster until you slur the words and your tongue will then be in the proper position for the trill.

Julian shared this link with me on Tuesday when we were practicing. It is funny but, it really helps. Good luck!!!
My favorite practice phrase (that someone posted on this site) is " El perro corre in el ferrocarril". The dog runs on the railroad tracks . My apologies to whoever posted this first. I use it alot. El perrrro corrrre in el ferrrocarril.
For what it's worth, I can't do it. I've been trying all my life. Because I wanted a machine gun when I was little playing cops and robbers..... but instead all I could have was a pistol. Now, as an adult, when I'm alone in the car I practice. I can get my tongue to vibrate/trill but I'm forcing so much air out that I get light headed. Soon as I try to make a sound on top of that, it's over. :(
I don't know why I never thought to do this before, but I did a Google search for adult native Spanish speakers who have problems pronouncing 'r' (It's common for little kids not to manage it)
My search sentence was: ¿Por qué no pronuncio bien la r? (Why don't I pronounce 'r' well?)
There are plenty of native speakers asking (and answering) this question.
Tongue tie is frequently mentioned, among other suggestions. (bad habits learned as children and not corrected, need to see a speech therapist, do exercises etc)
Here's a sample answer...
.la causa mas común es porque algunas personas tienen el frenillo de la lengua muy grande, eso se puede ver si tratas de levantar tu lengua con la boca muy abierta si no logras tocar tu paladar o si tu lengua se ve como dividida en dos es muy probable que sea esta la causa.
The most common cause is that some people's tongues have a thick frenulum, it can be seen if you try to raise the tongue with your mouth open, if you can't touch your palate or if your tongue looks as if it's divided into 2 parts then this is probably the cause. (I wouldn't describe it that way, but I know what he means, I can clearly see the centre of the tongue firmly held down, with the sides lifting up.)
The good news - unless the tongue-tie is very severe you can, like I have, practise like mad with tongue-twisters and exercises, and get close enough to pronounce many 'r's' better than when you started.
Don't give up!!
The phrase that I was taught (and still gives me trouble, hehe) is:
"Erre con erre cigarro, erre con erre barril. Rapido corren los carros por la línea del ferrocarril."
PS. I have bolded all the r's that require a hard roll.
Put the tip of your tongue on the ridge behind your teeth. Push air through. Forcefully.
In any case, this is how I do it. From my experiences, everyone has a different way to describe it, to learn it, and maybe even to do it. Search every way possible and try each. Remember that you can't learn to do it unless you actually make some NOISE! :D
Welcome to the forum.
I guess probably everyone who ever visited this site has asked that question. Your best bet is to go to the search box at the top of the page and enter ** how to roll**. This will find how to roll your r's, how to roll your rr's, how to roll your R, etc.
Check out this blog post!
Hope it helps!
Rolling my r's isn't that much of a problem for me, it's just that I forget to do it most of the time, especially when I'm speaking quickly. I can't believe how many times I get away with it... but I shouldn't. 
Soy un hablante nativo de español y creo que se aprende a rodar la lengua de manera natural, desde nuestra primera infancia, haciendo ruidos raros como "rrrrrr", imitando el sonido de los coches, camiones o motocicletas, como dijo Goyo. Para mí, por ejemplo, es muy difícil pronunciar el sonido gutural de la 'r' como lo hacen los franceses o los alemanes. No sé si alguna vez podré ser capaz de hacerlo.
Todavía disfruto mucho imitando el sonido que hacen los tráilers cuando frenan con motor: ¡Prrrrrrr.....!
I am a native Spanish speaker and I think we learn to roll our tongue naturally, from our early childhood, making funny noises like 'rrrrrr', imitating the sound of cars, trucks or motorcycles, as Goyo said. For me, for example, it is very difficult to pronounce the guttural sound of 'r' as do the French or the Germans. I do not know if I will ever be able to do that.
I still like to imitate the noise made by the 18-wheelers when using jake brakes: ¡Prrrrrrrrrrrr....! It is very funny for me.
Practice alot and have a healty snack of meat balls, doughnuts, and cherry tomatoes.
