Grammar inquiry.

[combes]

Hello everyone,

I'm looking for grammatical mistakes if any.

Since many people are being away from doing exercises that are required for thier health, four colleagues and I decided to build a gym to help them and thus reduce the consequences of this health issue. As a mechanical engineer my job is to look for the best equipment and machines can be used in the gym and to fix what needed to be fixed.

If you notice something wrong then, let me know pleaes.

thanks in advance.

Since many people don't take enough exercise to benefit their health, four colleagues and I have decided to build a gym to help them out and thus help minimize any risks that lack of exercise might entail. As a mechanical engineer, my job is to look for the best equipment and machines out there that can be used in the gym and fix what needs to be fixed.
