What weight capacity should I look for if I want to add a weight belt?

Once you're doing weighted pull-ups, reviewers across r/bodyweightfitness and r/GarageGym strongly recommend wall- or ceiling-mounted hardware rated at 400 lbs or higher and bolted into studs or joists with lag screws. Doorway bars rated 440 lbs technically pass the static-load math, but specialist communities consistently warn that dynamic loading (kipping, dropping, jerks) is what fails cheap doorway hooks, not bodyweight alone.
