We created these pull up bars [1] years ago and continously try to improve them or introduce some new models, but, all in all, without great success. If you're into something, then it's difficult to think out of the box. So fresh eyes are needed! Any feedback would be a great help. Maybe you see another model, a new feature or a new design that would be cool to make. Thanks!
