I think it is better to exercise outdoors than in a gym with equipment.

There are some reasons to support my opinion.

Most of all, in outdoor, there is a fresh air by exercising outdoors, we can enjoy fresh air.

These days, because of[또는 due to] corona virus, exercise exercising[동명사] in a gym with equipment may can -> may는 일수도 있고 아닐 수도 있지만 아닌 확률이 더 큰 경우에 쓰입니다. be danger dangerous. And Also, I can make many friends. Umm, when I was a freshman, I exercised outdoors sometimes and I made many friends during the exercise that time, and I keep touching still keep in touch with them until now. So I think it is better to exercise outdoor outdoors.-> outdoor가 아니라 outdoors입니다.
