GZCLP

Created by powerlifter Cody LeClair. A four-day linear progression program using three tiers of diminishing specificity and increasing volume. Tolerates more training stimulus than Starting Strength while remaining appropriate for beginners and early-intermediate lifters.

Design Philosophy — Why Three Tiers

GZCLP is built around Cody LeClair's observation that simple 5×5 programs (Starting Strength, StrongLifts) produce diminishing returns after 2–3 months because they only train one quality: heavy low-rep strength. The tier system solves this by training three qualities simultaneously, each with its own progression:

Tier 1 (heavy, low-rep) trains maximal strength through the competition lifts at 5×3. This is the same stimulus as Starting Strength, but at slightly lower reps per set — which means heavier loads for the same number of total reps. The AMRAP last set provides autoregulation: if you crush the set, your training max is probably conservative; if you barely get 3, it's well-calibrated.

Tier 2 (moderate, moderate-rep) trains the same movement pattern at 3×10 with lighter weight. This accumulates hypertrophy volume that a pure strength program lacks. More muscle cross-sectional area means a higher strength ceiling later. T2 progresses independently of T1, so you can keep building muscle even when your heavy strength stalls.

Tier 3 (light, high-rep) is isolation work for weak points and joint health. It produces the least fatigue per set and addresses imbalances that compound lifts miss.

Why the failure cascade matters: When T1 stalls at 5×3, you don't deload — you change the rep scheme to 6×2, then 10×1. This extends the linear progression by reducing reps per set while increasing total sets, so you can continue adding weight by reducing per-set difficulty. Only after exhausting all three rep schemes do you reset. This gives beginners 3–4 months of additional progression compared to programs that deload at the first stall.

Four-Day Schedule

Day	T1 — 5×3+	T2 — 4×10	T3 — 3×15+
1	Back Squat	Bench Press	Pull-ups
2	OHP	Deadlift	Pull-ups
3	Deadlift	Back Squat	Pull-ups
4	Bench Press	OHP	Pull-ups

Tier Definitions

Tier	Sets × Reps	Purpose	Progression trigger
T1	5×3 + AMRAP	Specificity — competition lift strength	Every session: +5 kg lower / +2.5 kg upper
T2	4×10	Supplemental volume at sub-maximal load	All 40 reps completed cleanly
T3	3×15+ AMRAP	Accessories / GPP	≥ 25 total reps across 3 sets

T1 Failure Cascade

Failure	Response
1st fail	Switch to 6×2 at same weight next session
2nd fail	Switch to 10×1 at same weight
3rd fail	Reset load −15%, restart at 5×3+

Common T3 Accessories

Session slot	Examples
Upper T3	Pull-ups, dips, face pulls, triceps pushdown
Lower T3	Leg press, lying leg curl, calf raise, ab wheel
