Running a 5x5 for the first time — any tips?

Starting a simple 5x5 next Monday. How long did you stay on it before switching? Any warm-up protocols you swear by?

Stay on it until the main lifts stall for two full weeks. Warm up with empty bar then progressive sets — do not jump straight into working weight.

Sleep and protein matter more than fancy accessories early on. Keep the program boring and consistent.
