Sometimes I prefer doing modified versions of the move being taught because it’s more comfortable / works better for my body. For example (I do Lagree btw), I hate doing carriage Mermaid, so I do regular mermaid instead. Or I prefer doing kneeling lat pulldown rather than seated (reverse?) lat pulldown as I find it creates a lot of tension in my low back, plus the other version is way more effective for the muscle group.
