Homework for my Korean course

요즘은 운동을 하지 않지만 어렸을 때는 수영을 보통 했어요. 그리고 저는 제가 살고 있는 도시공원으로 산책을 자주 나갔어요. 저는 스노보드를 타보고 싶어요. 스노보드는 극한 스포츠처럼 보있어서 스노보드를 타기가 재미있을 수 있다고 생각해요. 배구를 해봤지만 제대로 할 수가 없었어요.

Can someone correct my text please? I'm still a beginner, so that's why I didn't use very advanced grammars and vocabularies. English is not my native language, so forgive me if I made any mistakes. This is what I need to do: 1. Record a video of up to 30 seconds talking about sports, hobbies or activities in general that you enjoy doing, as well as things you want to try doing one day (use -아/어 보다).

What I meant: I don't exercise these days, but I often swam when I was younger. And constantly goes for a walk in the city park where I used to live. I want to try snowboarding. Snowboarding seems like an extreme sport, so I think snowboarding can be fun. I tried volleyball, but I couldn't play it right.
