Using light weights (just a few pounds, more would likely hurt your wrists). Bend your elbow and rest it on a flat surface. Keep your forearm straight, and bend your wrists (whilst holding the weight, of course), so-so many times (not sure). Backwards, forwards. If you do it sideways make sur eyou don't straight your wrist too much (sore wrists are hell).

Note: there's not much you can do to make your wrists thicker. Unless of course you want to get nice and fat :P. And, there's not a great deal of muscle there to pump up. So. *shrug*

I have small wrists too.
but bigger upper arms..
I really don't know what advice to give? :confused:

I know the perfect solution, I work out and I actually do this once in a while, hold on let me explain



Get a weight, maybe 35-50 pounds or however much you think you can carry with about half an arm

Put your arm on a table with your palm upwards towards the cieling

Now, put your hand over the edge of the table and stop at your wrist

Do reps straight up and down 180 degree angle

It might hurt at first though

It works on your forearms and wrists

Niice.

get those things for tennis, the wrist squeezers.

These axercises will mostly work out your forearms. Wrist size is largely genetic.

Do exercises using moderately heavy objects. then maybe your wrist is getting stronger and thicker....

I can think of something...

There is not really a muscle on your wrist. You are stuck with an undersized wrist for the rest of your life. Thank your mom and dad.

There are wrist squeezers, these things where u squeeze it (it has resistance) and it builds ur forearm muscle. You can also do wrist curls, you hold a dumbell (not too heavy) and instead of moving ur whole arm, just curl your wrist up and down.

resistance bands will help i like them because you can change the tension and you can do tons of work outs with them and they are cheaper then buying tons of weights
