GZCL P-Zero: The Next Evolution in Strength Training

Created by renowned strength coach Cody Lefever (GZCL), P-Zero is the latest advancement in the popular GZCL training methodology. Building upon the success of GZCLP, a linear progression system embraced by over 50,000 lifters worldwide, P-Zero introduces enhanced flexibility and customization for lifters aiming for both strength and muscular development.

Why Choose GZCL P-Zero?

  • Proven Methodology: Utilizes the successful GZCL pyramid structure (T1, T2, T3) to strategically balance strength and hypertrophy.

  • Adaptable Progression: Whether your goal is powerlifting, bodybuilding, or general strength, P-Zero can be tailored precisely to your objectives.

  • Structured Yet Flexible: Clearly defined guidelines enable you to confidently build your own progression, keeping workouts fresh, engaging, and effective.

How the GZCL Pyramid Works:

  • Tier 1 (T1): Peak Strength

    • Main compound lifts (squat, bench, deadlift, press).

    • Heavy sets at 85%-100% of your training max (TM).

    • Designed for maximal strength development (10-15 total reps per workout).

  • Tier 2 (T2): Strength & Volume

    • Compound movements or variations performed at moderate intensity (60%-80% TM).

    • Volume-focused to complement T1 lifts (20-30 total reps per exercise).

  • Tier 3 (T3): Hypertrophy & Foundation

    • Isolation and accessory exercises using lighter weights for higher reps.

    • Focuses on muscular growth, foundational strength, and injury prevention (30+ total reps per exercise).

Introducing P-Zero Ultra Singles Progression:

  • Optional singles-based progression to build strength, confidence, and technical proficiency.

  • Utilize singles at or above 90% TM for focused intensity.

  • Clearly defined stages (Stage 1: triples, Stage 2: doubles, Stage 3: singles), allowing progression based on performance rather than arbitrary timelines.

Who is GZCL P-Zero for? Ideal for intermediate to advanced lifters looking to:

  • Break plateaus with structured yet adaptable programming.

  • Integrate powerlifting-inspired strength principles into their routine without exclusively training for competition.

  • Take ownership of their training progression, customizing as they advance.

Your Progress, Your Pace: P-Zero provides the tools to continually challenge yourself with heavier lifts, new exercises, and adaptable volume. By cycling through progression stages and adjusting intensity strategically, you'll build unstoppable momentum toward your strength and physique goals.

Join thousands of lifters who have transformed their training with GZCL methods. It's time to evolve your strength journey with GZCL P-Zero.

I gained significant strength. I reduced the volume to 2 sets per exercise.

Gustavo Calvache

Love it, great results, feeling really strong able to get proper rest firing the week. Unfortunately, this will be my last week, I am moving towards a program that I really can make it in 45-60 min. That is the only downside for me, if you have time, give it a try

Mike J.

Pretty effective, the high volume seemed to really help, and avoid injury at the same time. I prefer this to other GZCL programs I've ran previously. Made minor changes due to equipment, added a little bit more arm reps just because.

Well written program. The p zero ultra singles are really fun. I also like the approach to the T3 volume. Highly recommend

About Cody

Physical fitness has been a lifelong passion of mine. While serving with the U.S. Marines I began training myself and others to achieve a higher level of physical preparedness. This developed into a passion for lifting weights that took me to the powerlifting platform where I competed in multiple state, national, and world level championships. My clients range from military servicemembers to athletes to the average person desiring improved physical fitness, whether that be in sports or in daily life.

In 2022, I opened up North America’s Highest Gym in Almba, Colorado. Located at 10,361 feet elevation, Alma’s Gym is high up in the Rocky Mountains approximately 2 hours outside of Denver. It is a place for locals and tourists alike to get stronger and develop their bodies.

I officially partnered with Boostcamp App to launch GZCL Program (GZCLP) into an app format for free.

Common questions

P-Zero Ultra (GZCL 2.0) is a paid program available inside the Boostcamp app. You can browse the full week 1 schedule here for free, then purchase inside the app to unlock all 12 weeks with auto-progression and coaching notes included.

This program is built around a full gym. Make sure you have consistent access before starting, since the progression model assumes you can perform the same movements week over week. If you're missing something, the Boostcamp app includes substitution suggestions inside each workout.

Each session typically takes around 60 minutes to complete. That estimate covers your working sets but doesn't account for warm-up or rest between sets, so budget a little extra time when you're first learning the movements. As you get familiar with the program, sessions tend to move faster.

P-Zero Ultra (GZCL 2.0) is structured around 4 training days per week, with rest days built in to allow for recovery. Consistent rest is as important as the training itself. Skipping rest days can stall your progress. The app lets you reschedule sessions if your week doesn't go to plan.

The program runs for 12 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go. Many athletes choose to repeat the program after finishing, either at a higher starting weight or with a different variation.

P-Zero Ultra (GZCL 2.0) is available inside the Boostcamp app, free on iOS and Android. Once you download the app, you can search for the program by name or find it on the coach's profile. The app tracks all your sets and weights automatically, so you always know exactly what to do next session.
