I am not sure if this kind of dynamic flexing and posing is even possible to contain within a single LoRA. Nevertheless, I would like you guys to give your best to serve me some common posing and flexing positions of bodybuilding (e.g. shown in championships, gyms, ...). Ideally it should rotate through a set of posing but react to view and position prompts. It can optionally be used on male and/or female as well as anthro and furry species.
Let me know if there are problems with realizing such a dynamic thing. :)
