I liked this poem alot had some good lines in there keep it up good job

"Gymnastics,a great feeling"

Put a space after the comma.

"One of my favorite sports
Of all sorts

There are many to choose from
But this is one I love"

I felt these four lines to not be descriptive enough, I think you could create a lot more imagery, the wording just felt weak to me.

"Doing tricks on a beam
May be scary to some that have seen

But to me it brings no pressure
And to me there's nothing better"

That's really cool that you do that, it seems like a cool sport to do. Good wording in these lines.

"Vault is exciting
As long as you're sharp and tight

But there's nothing like bars
Doing tricks on them is nothing hard"

The flow was rocky here. In the fourth line, use other words instead of what you already stated earlier "doing tricks". Maybe reword that line to: "Spinning on them is nothing hard" or something like that.

"And floor is my favorite
It is so great you just want to capture the image in your mind and save it
After you've done a trick so great"

That second line was way too long, it threw the reader off because the flow was bad.

Reword maybe to this:

"It's so thrilling and mind-blowing,
You want to forever save that image."

Otherwise, 4/5 from me, I didn't get much out of this piece, I just thought you could word things more creatively, be more original.

Take care and God Bless You!
