'(to) exercise' in Japanese

[sleepsheep]

Hi!

I've got confused about the Japanese translation of the verb 'exercise'.
In my dictionary it says: undou o suru
and in another source: undou suru

Now, with or without particle - which one is right??

Thanks for answers!

Both are correct, but うんどうする is more common. The を is usually dropped for most nouns that are used as verbs.

The difference would be between "to do an exercise" (うんどうをする） and "to excercise"　（うんどうする）

Is this the same for "benkyou suru"?

If I've spelt it wrong, I mean "to study".

[Harisenbon]

Yup

Ok, thanks.
