This LoRA is meant to capture Jo Landis, an online fitness model. A weight of 0.8 works ok. Be warned, there was limited training data so the LoRA is a bit over-baked.

The LoRA tends to make him twinkier than he is. Use muscular to age him up. By default his hair is a bit messy, use tousled hair or messy hair in the negative to clean it up. You can also use buzz cut or fade hair cut to give him shorter hair.
