The Anima version of this model is trained on the Preview 3 release of Anima. This version works quite well with most Anima models I tested. Sometimes the weight needs to be adjusted. For me, it worked best between 0.8 and 1.0. If you add the tag huge pectorals to the prompt, it can result in a massive increase of the muscle mass. Recommended settings: Strength: 0.8-1.0 Trigger: muscular female, big muscles, pectorals Optional: huge pectorals, abs, thick thighs, thick arms, biceps, veiny muscles...
