I think to limit your interpretation of “worthy” or not to give advice to a benchmark of strength, at any level, is a little small minded. There is merit in accomplishment, and certainly those who have achieved a lot can offer advice to people who want to do the same, but strength, at any level is not the only achievement to be made. Peoples proudest achievements may be that they lost weight, or gained it, that they became leaner, or more muscular, or stronger, or simply more fit, more healthy
That they became happier, that they overcame anxiety and joined a public gym. There are so many achievements for people to make, more than just strength, and every one of them is a difficult journey that they are qualified to give advice for. Maybe some advice won’t work for everyone, maybe it will. But we’re a community, that means we share. It’s not all vanity, all “look at me and praise me” it’s personal, and people, and sharing
Someone who was underweight and struggled to eat, but still managed to gain ten, twenty, thirty, however many pounds, and worked their ass off to get to where they are. Their experience qualifies them one hundred times over to share advice and help people with similar problems
