6-12-25 Method For Bigger Legs

May 12, 2022

Here's what you need to know about the 6-12-25 Method giant sets:

  • First Exercise - Mechanical Tension: Use a heavier weight for 6 reps for submaximal strength.
  • Second Exercise - Muscle Damage: Use a moderate weight for 12 reps for hypertrophy.
  • Third Exercise - Metabolic Stress: Use a lighter weight for 25 reps for strength-endurance.

The late Charles Poliquin recommended taking these sets to near failure, but I'm a firm believer in keeping 1-2 reps in reserve (RIR) as research has shown that 1-2 reps in the tank are all that's needed to induce muscular hypertrophy. It's also far more sustainable this way and won't cripple you for 10 days.

While the 6-12-25 Method is a great method to spark new gains, it's not a method I'd use for longer than 6 weeks as people can burn out quickly on this one (which is why my 6-12-25 program is only 6 weeks in length.) I'd highly recommend starting slow this one with regards to loading and total sets performed - less is more out of the gate.
