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 it's for
Reviews
I love the upper lower split of this program. It also accounts for fatigue build up and deloading week, which is something I learnt the hard way that I needed. Noticeable strength gains for sure. Will be doing this again.
Good so far
Takes a lot of guesswork out, pushes the limits of strength while also obtaining an amazing pump in each workout.
Not a replacement for GZCL LP. Poor progression and not enough volume.

The coach
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.
How P-Zero Ultra (GZCL 2.0) works
P-Zero Ultra (GZCL 2.0) is a standard-length, 12-week, 4-day-per-week strength program written for beginner lifters. Each session takes around 60 minutes to complete. It was created by Cody Lefever and is published on Boostcamp with full week-by-week structure built in.
The program runs as a 12-week block with the same training-day structure throughout. It's built around a full gym setup. Inside the Boostcamp app, working weights and targets auto-progress between sessions based on what you actually lifted, so you don't manage the math by hand.
P-Zero Ultra (GZCL 2.0) is appropriate for new and returning lifters. The session-by-session structure removes the guesswork that usually stalls beginners. Over 1,052 Boostcamp athletes have run it. Browse week 1 here for free; unlock the rest inside the Boostcamp app.

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.
