Now, when it comes to your essay, I found several points for you to be considered explained as follows:

The common issues that I noticed is SVA or Subject-Verb Agreement, below are the SVA problem in your essay:
"..exercises aids us.." (the subject is plural, use verb 1 instead; this is also the same problem I found in the following sentences)
"..exercises brings us.."
"Because it releases chemicals in our brain called endorphins that help us relieve tension, and reduce stress."

You put the word "us" too much. You can replace this word with its synonym, for example, "people". The essay is short so bear in mind that you need to use varied of words. Also, the lexical choices that you use must be appropriate or accurate to the context of your sentence.

Still, what I like from your essay the most is you have a good control of ideas. I can see that each sentence is linked each other and it is well-structured. Practice more, and you will be fine, 100% guaranteed! :D
