Flux isn't good at muscular females. I found this out when trying to prompt barbarian warrior girls. This LORA does cut physiques up to bulging muscles. Sorry for the typos in the trigger words.

I have a new version cooking already, but give this one a shot and show me your muscle mommies.

Lean trigger is a more cut physique and Large trigger is a bulkier physique. Can use derivirivefbb for somewhere in between.
