Known for its simplicity and power, this routine focuses on big, compound lifts performed with progressive overload. The 5×5 method has stood the test of time as a foundational program for anyone looking to build raw strength and muscle mass, combining intensity and full-body engagement.

Focus: The program revolves around five sets of five reps, focusing on compound movements. This approach not only builds strength but also enhances muscular endurance, making it a dual-purpose plan ideal for strength and size gains.

Key Program Features

  • 5×5 Sets and Reps: Each exercise is done for five sets of five reps, emphasizing lower reps at heavier weights to maximize strength gains.
  • Progressive Overload: Aim to increase the weight lifted each week or every few sessions. This gradual increase in weight is key to building strength and muscle.
  • Full-Body Focus: By hitting the major muscle groups three times per week, the body adapts to a high training frequency, helping build strength and muscle quickly.
  • Compound Exercises: Movements like the squat, bench press, and deadlift activate multiple muscle groups, allowing you to build mass and strength simultaneously.

How to Get Started with the Reg Park 5×5 Routine

  • Starting Weights: Begin with a weight that allows you to complete all sets and reps with good form. For the first couple of weeks, stay slightly conservative with the weight to prevent burnout.
  • Progression: Each week, aim to add 5-10 pounds on lower body exercises and 2.5-5 pounds on upper body exercises.
  • Rest Periods: Allow 2-3 minutes of rest between sets, especially for squats and deadlifts, as these are highly taxing exercises.
  • Consistency: Since this program involves heavy lifting and full-body training, consistency in both attendance and effort is key to seeing results.
  • Optional Accessories: Pull-ups, dips, and chin-ups can be added to the end of the workout if time and energy allow, giving a little extra boost to the upper body.
