an English question

limits and limitations aren't exactly synonyms. But they do have some of the same meanings and you can use limits to replace limitations sometimes. In the sentence you have, it sounds like you would be able to replace the two.

i would say yes. limitations is just a bit more of a 'proper' form.

no. limits will deep than limitations. you have hard to do things to get limits. but you are easily to get limitations. that's the difference about limitations and limits. often the sportor will use limits .and normal persons in the society use limitations.

Not really! Limitation essentially means shortcomings and is more related to quality. As in, something you do might not be that convincing. On the other hand, limit would be more related to quantity as to which will have a threshold value, even if you're actually capable to go beyond. In other words, limit would mean a restriction.
