The 6 12 25 rule is a proven strength training method that uses three different rep ranges to build muscle, strength, and endurance all in one workout. This system combines 6 reps for strength, 12 reps for muscle growth, and 25 reps for endurance and muscle definition.
How Does The 6 12 25 Rule Actually Work?
The 6 12 25 rule works by targeting different muscle fibers and energy systems in your body. When you lift heavy weights for 6 reps, you build maximum strength. The 12 rep range hits the sweet spot for muscle growth. The 25 rep range improves your muscle endurance and helps burn fat.
Research shows this approach is more effective than sticking to just one rep range. A 2019 study found that people who used multiple rep ranges gained 40% more muscle than those who only did one type of training.
What Are The Three Parts Of The 6 12 25 Rule?
- Use 80-85% of your maximum weight
- Rest 3-4 minutes between sets
- Focus on compound movements like squats and deadlifts
- Builds maximum strength and power
- Use 65-75% of your maximum weight
- Rest 2-3 minutes between sets
- Perfect for building muscle size
- Most effective range for hypertrophy
- Use 40-50% of your maximum weight
- Rest 1-2 minutes between sets
- Improves muscle endurance
- Helps with fat burning and muscle definition

What Common Mistakes Should You Avoid?
