Definition
The 5×5 protocol is five sets of five reps at a heavy but manageable weight, typically on squat, bench, overhead press, and row. It's the backbone of programs like StrongLifts and Starting Strength. 5×5 builds raw strength and technique in beginners, but advanced lifters usually need more volume variety.
Real questions
Is 5×5 good for muscle growth?
It's decent for beginners, but hypertrophy usually responds better to slightly higher reps (6–12) and more total sets.
How much rest between 5×5 sets?
3–5 minutes. These are heavy sets — short rest will drop your weight by set 3.
