LORA weight: -3 to 4+
-2 to 3+ for IXL 2.0

This is a slider, Lora, so you can choose whatever weight you want, so experiment and find what suits you best. A positive weight adds abs. You can use even higher weights such as 8 and above it all depends on characters and checkpoints.

You can also add sagging breasts to your prompt to make it have an even stronger effect.
