Best Apps for GZCL & GZCLP: 3 Workout Apps Compared (2026)

GZCL is Cody Lefever's tier-based strength framework, built around T1 (heavy compound), T2 (supplemental compound), and T3 (accessory) work with a 1:2:3 weekly volume rule. GZCLP is the linear progression variant for beginners. These three apps either ship the official GZCL programs as pre-built content or are dedicated to the GZCL family.

Boostcamp

US App Store
4.8 ★ (8.8K)
Pricing
Free tier + Pro at $59.99/yr ($4.99/mo annual), 7-day trial
Platforms
iPhone, iPad, Apple Vision, Android

Why it's on this list

Boostcamp ships all four official Cody Lefever GZCL programs free: GZCLP (the 12-week linear progression entry point), The Rippler (12-week intermediate), Jacked and Tan 2.0 (12-week hypertrophy-focused), and P-Zero Ultra (GZCL 2.0), plus Geoffrey Schofield's GZCL-framework Wayjacked Machine. Each is ready to run with the tier scheduling and 1:2:3 weekly volume rule already set up.

GZCL's structure is exactly what makes the tracker matter: three tiers a session, each with its own intensity and rep target, and an AMRAP on the last T1 set that drives progression. Boostcamp lays the T1, T2, and T3 work out in order, records the AMRAP, and advances the loads on the variant's schedule. Adjusting T3 accessory volume set by set takes two taps, RPE and RIR are loggable on every set, and the plate calculator covers the heavy T1 and T2 lifts. No part of that is paywalled.

Cody Lefever first shared the GZCL family as spreadsheets on Reddit and Lift Vault, and turning programs like that into tap-to-run app content is what Boostcamp was built to do. GZCLP sits in the library beside 5/3/1, nSuns, and 11,000+ others, so progressing through the GZCL variants (or jumping to another methodology) keeps one continuous history. Pro adds the Strength Score, a per-muscle volume heatmap, and 20+ exclusive coach programs for $59.99/year ($4.99/month annual).

Best for: Lifters who want all four official GZCL programs pre-built with T1/T2/T3 tier tracking, plus a library for what comes after the GZCL block

Liftosaur

Pricing
Free tier + subscription or lifetime (lifetime around $70 to $100)
Platforms
iPhone, Android, Web

Why it's on this list

Liftosaur ships GZCLP as a pre-built program in its catalog and supports the full T1/T2/T3 tier structure on its standard tracker. The program runs with auto-progression baked in, and you can run it on iPhone, Android, or the Liftosaur web client.

What sets Liftosaur apart is Liftoscript, a plain-text scripting language for defining custom workout programs with arbitrary progression rules. If you want to build a custom GZCL variant (a non-standard T2 movement pattern, alternative T3 schemes, or a hybrid with another methodology), Liftosaur is the only one of the three that supports that workflow directly. The web client is particularly useful for designing GZCL-framework programs on a laptop, then syncing to mobile.

Best for: Lifters who want pre-built GZCLP plus the ability to script custom GZCL-framework variants in plain text

Frequently asked questions

Why is Boostcamp ranked first for GZCL and GZCLP?

GZCL runs on a three-tier structure (T1, T2, T3) with an AMRAP on the top set driving progression. Boostcamp ships all four official Cody Lefever programs (GZCLP, The Rippler, Jacked and Tan 2.0, P-Zero Ultra) free, with the tier scheduling and AMRAP progression handled for you. The dedicated GZCL app is excellent for the GZCL family specifically; Boostcamp adds the rest of the library and keeps one continuous history when you move between programs.

What should I run after GZCLP?

GZCLP is the linear-progression entry point to the GZCL family. The usual path is GZCLP first, then The Rippler or Jacked and Tan 2.0 as you advance, then P-Zero Ultra or a different methodology entirely. Boostcamp ships every step of that progression in one library, so your lifts and personal records carry from one GZCL variant to the next without re-entering anything. That is the practical difference between a programs library with a tracker built in and a single-program logger.

Is GZCLP free, and what do the paid tiers add?

GZCLP and all four official GZCL programs are free on Boostcamp, including the tier scheduling, AMRAP progression, plate calculator, and charts that run them. The dedicated GZCL Method Workout Logger is also free to run GZCL, with a one-time $9.99 Pro unlock for charts and a plate calculator. On Boostcamp those are already in the free tier; Boostcamp Pro ($59.99/year or $4.99/month annual) adds the Strength Score, a per-muscle volume heatmap, and 20+ exclusive coach programs rather than gating GZCL itself.

What is the T1, T2, T3 tier system in GZCL?

GZCL programs are built around three exercise tiers per session. T1 is a heavy compound lift (squat, bench, deadlift, or overhead press) programmed for high intensity at low rep ranges. T2 is a related compound lift, typically a close variation of the T1 movement, programmed at moderate intensity and volume. T3 is isolation or smaller-compound accessory work for hypertrophy and weak-point targeting, programmed at higher rep ranges. GZCL programs apply the 1:2:3 volume rule across the tiers (rough rep-count distribution across the week). All three apps support the tier structure: Boostcamp and GZCL Method Workout Logger ship it as pre-built program content, and Liftosaur lets you script it via Liftoscript or run its pre-built GZCLP.

Should I start with GZCLP or jump into The Rippler or Jacked and Tan 2.0?

GZCLP is the linear progression variant designed for beginners (lifters with under 12 months of consistent training, or lifters who can still add weight to the main lifts every session). It uses the same T1/T2/T3 framework but with simpler progression rules and lower weekly volume. The Rippler is an intermediate template that introduces percentage-based progression. Jacked and Tan 2.0 layers heavier hypertrophy work onto the GZCL framework and is best for lifters who have already completed at least one GZCL cycle. P-Zero Ultra (GZCL 2.0) is the most advanced of the four. Boostcamp ships all four, so you can move between them as you progress.

Can I customize GZCL accessory work?

Yes on all three apps, but the workflow differs. Boostcamp's program editor lets you swap accessories and adjust T3 volume in two taps, and the visual custom program builder lets you create your own GZCL hybrid from scratch with no scripting required. Liftosaur's Liftoscript supports arbitrary progression and accessory rules via plain-text scripting (more flexible, steeper learning curve). The GZCL Method Workout Logger lets you customize accessories directly via in-app settings.

Best apps for 5/3/1

5/3/1 is Jim Wendler's percentage-based strength template, built around four core lifts and a four-week wave. Most workout apps treat 5/3/1 as a custom routine you build from scratch. These four apps either include 5/3/1 as a pre-built program or are dedicated to the methodology, so you can start a cycle without doing the math yourself.

Best apps for nSuns

nSuns 5/3/1 is a high-volume linear progression program created by Reddit lifter 'nSuns' (Cody), built around 9 working sets on the top main lift and weekly AMRAP-driven progression. It's described in the community as 'Wendler in the front, Sheiko in the back'. Most workout apps treat nSuns as a custom routine you build from scratch. These three apps either ship the official nSuns template or are dedicated to nSuns specifically.
