GZCL: The Rippler

The Rippler is Cody Lefever's intermediate GZCL template. Where GZCLP handles novice linear progression, the Rippler waves T1 reps across a 12-week cycle. Heavier each week, lower reps each wave, building into a peak.

How it works

The Rippler is built around the GZCL method's three-tier structure. T1 is the main lift of the day: heavy, low-rep, under 5 reps per set. T2 is the supplemental lift, usually a variant of the T1 (paused bench for bench, front squat for squat) at moderate intensity and rep range. T3 is accessory work: isolation and bodybuilding movements for volume and muscle growth. The Rippler's innovation is in how it waves the T1 rep scheme across a 12-week block.

The cycle rolls through four waves of three weeks each. Wave 1 is the 6-rep wave: T1 sets are 6 reps at climbing percentages across three weeks (72%, 75%, 78% for week 1-3). Wave 2 is the 4-rep wave: T1 sets are 4 reps at 78%, 81%, 84%. Wave 3 is the 2-rep wave: 84%, 87%, 90%. Wave 4 is the 1-rep wave, which peaks into a new training max: 90%, 92.5%, 95%. Each wave ends with a test — a top set at the target rep range, and if the lifter hits it, the training max for the next wave is calculated from the performance.

T2 work sits at 70-80% of the T1 training max for 3 sets of 6-10 reps. This is where most of the hypertrophy volume comes from, and the variant selection drives weak-point work: paused bench for lifters with chest-press sticking points, deficit deadlifts for lifters weak off the floor, pin pressing for lifters who miss bench attempts at lockout.

T3 accessory work is programmed as 3 sets of 10-15 reps per exercise, focused on back and arm volume for upper-body days and hamstring and quad volume for lower-body days. The Rippler does not prescribe specific T3 exercises. The lifter picks based on weak points and equipment access. This differentiates the Rippler from programs like 5/3/1 that prescribe accessory templates rigidly.

Because the Rippler is four sessions per week with the same main lift hit once per week, it works well for lifters who need time to recover between heavy sessions but want more total volume than a three-day linear-progression template provides. The four sessions map to squat, bench, deadlift, and overhead press, with each session including T1, T2, and T3 for that lift.

Caveats

  • The Rippler requires honest AMRAP performance tracking to calculate the next wave's training max. Lifters who sandbag AMRAPs (stop short of the true limit) will under-project the training max and stall in wave 3-4 with weights that feel easier than they should. Lifters who overshoot AMRAPs (go past failure on form breakdown) will over-project the training max and miss working weights in the 2-rep and 1-rep waves.
  • T3 volume is prescribed as moderate. Lifters who come from bodybuilding backgrounds often pile on excessive T3 work and stall the T1 progression from accumulated fatigue. The Rippler is a strength program first; T3 exists to support the T1 progression, not to drive its own hypertrophy curve.
  • The Rippler is intermediate, not advanced. Lifters running GZCLP should complete the full GZCLP progression (typically 4-6 months) before moving to the Rippler. Starting the Rippler without a solid T1 base built through GZCLP often produces a stalled wave 3 as the lifter hits percentages their true 1RM cannot support.
