What compound lifts and rep schemes work best for a 3-day full-body routine?

[Paisley_T]

I'm getting back into a consistent gym routine after a long hiatus and want to establish a simple, effective full-body workout I can do three times a week with basic equipment like dumbbells and a bench. My main goals are building general strength and improving muscle tone without spending hours in the gym each session. For those who follow a similar schedule, what compound exercises and set/rep schemes have you found most efficient for hitting all the major muscle groups, and how do you structure your warm-up and progression to avoid plateaus and injury?
