The bars in my facility have been scraped repeatedly by the Team girls with a metal wire scraper. The bars are now totally trashed and scratched, and it is destroying all the girls hands to the point where even team girls are saying they can't do bars because it hurts too bad. Another coach for the facility said the girls just need to develop their calluses more, and this won't be a problem. However I have swung on them, and I disagree with the other coach. The bars are bad. You can see the grooves into the wood from the metal scraper, and I don't think all the calluses in the world are going to save their poor hands. Has anyone else encountered this problem? Is there much I can do to fix it, or even slightly improve it? Thanks.
