GZCL UHF

What is GZCL UHF?

UHF stands for Ultra High Frequency, and it's exactly that: Cody Lefever's five-week, five-day GZCL block where the point is practising the lifts far more often than a normal split allows. In GZCL terms, every exercise slot is graded by specificity and load — the T1 slot holds the day's heaviest, most competition-specific barbell work, the T2 slot holds a moderate-load variation of a different movement pattern, and T3 is accessory volume. Because the T2 always comes from the opposite half of the body, the squat pattern ends up trained three times a week (back squat, pause squat, front squat), the deadlift twice (the pull itself plus Romanian deadlifts), and pressing up to six times across bench, incline barbell and dumbbell work, close-grip bench and overhead press.

The week runs Monday to Friday: squat, bench, deadlift, incline bench, front squat, each as that day's T1. Every T1 finishes on a plus set, so you get a small readiness test five days a week, and the whole routine compresses what most programs spread over twelve weeks into a five-week wave that ends with max singles.

Is GZCL UHF right for you?

This is the advanced entry in the GZCL lineup, and the frequency is the filter. If you can train five days a week, recover quickly, and already handle percentage work near 90% without falling apart, UHF is a sharp short peak before a meet or a max test. If any of those aren't true, don't force it — the Rippler delivers a longer, gentler wave on four days, and Jacked & Tan 2.0 covers the volume-first months. It also assumes accurate current maxes on five different barbell lifts, so it rewards lifters with a deep training log.

How progression works

Everything is a percentage of the true 1RM you set on day one; the block is too short for mid-cycle adjustments, so the wave is pre-baked. T1 climbs 3×4 at 81% in week one and 4×3 at 86% in week two, wave-loads in week three (a triple at 83%, a double at 88%, then singles at 93%), hits flat heavy singles at 90% in week four, and peaks in week five with a triple at 86%, a double at 90% and a max single from 95% — every working week capped by a plus set. The T2 variation builds the opposite way — sets of 10 at 57% down to fives at around 72%, an AMRAP top set on the week-four reset, then a single light opener in week five. T3 accessories chase max-rep sets against a shrinking target and a shrinking set count: five sets at 12–15, five at 10–12, four at 8–10, three at 6–8, then one final set. Durata seeds all five maxes from your logged e1RM and runs the tier-appropriate rest timers, which matters when Tuesday's volume decides Friday's bar speed.

Durata runs this progression for you — every session's weights are computed automatically from your training maxes and logged AMRAP sets.

Percentages are of your training max (TM). AMRAP = as many reps as possible on the final set.
