This is the final form of my barbell handle project. Some things I noticed after creation was that the handle seems much too long. If I were to go back and do a second iteration, I believe shortening the length of the handle by and inch and a half to two inches would make it the optimal size. In addition, I believe shrinking the diameters slightly may help with the barbell gripping issue, as I believe it may be a bit too large for most people, although to me, it seems like a good size (I have large hands). Adding these two changes I believe would make it an overall better design.
