Realistically, am I kidding myself that I will be fine without barbells? I would be fine with adding dumbbells and kettlebells at any weight. Does this work? My goals pretty much align with the idea around this article: I want to stay healthy, long. I do not want to injure myself. Looks are of no concern to me.
I understand that workouts are a topic with strong opinions. If you are into barbells you probably also do it because you believe it's necessary. Given a level response on this might not be simple but it would be much appreciated
