Disciplined Monday to Friday, completely fall apart on weekends. How do you keep momentum?

During the week the structure carries me, I code before work, review at lunch, it just happens. Then Saturday hits, the structure's gone, and I tell myself I'll do it later and later never comes. By Monday I've lost the thread and spend an hour just remembering where I was.

Do you push to keep the streak alive every single day, or protect the weekend as real rest and accept the Monday ramp-up? Curious what actually works for people over the long term.
