Glossary — Key Terms

A quick reference for the jargon used throughout the program and this guidebook. Skim it once; come back whenever a term trips you up.

TermMeaning
HypertrophyGrowth in muscle size — the goal of this program (distinct from training purely for maximal strength).
TensionThe force created within a muscle as it is loaded and stretched. The main driver of hypertrophy; everything else serves it.
RPE (Rating of Perceived Exertion)How hard a set felt on a 1–10 scale, based on reps left in the tank. RPE 10 = failure. See The 6 Training Principles for the full scale.
RIR (Reps In Reserve)The flip side of RPE — how many reps you had left before failure. 0 RIR = RPE 10 (failure); 2 RIR ≈ RPE 8.
FailureTrying and being unable to complete another rep with good form. The last set of each exercise goes to failure (except intro/deload weeks).
Early SetsEvery working set before the last one. Stopped ~1–2 reps shy of failure (~RPE 8–9). Not warm-up sets.
Last SetThe final working set of an exercise — taken all the way to failure, and where intensity techniques are applied.
Double ProgressionThe primary progression method: add reps until you hit the top of the rep range on all sets, then add weight and drop back to the bottom of the range. Reps first, then weight.
Progressive OverloadContinually giving the muscle a new stimulus over time (more reps, more weight, better technique/mind-muscle connection) to keep it growing.
The Negative (Eccentric)The lowering/lengthening phase of a rep. Controlled over 2–4 seconds on most lifts — more important for growth than the lifting phase.
The Positive (Concentric)The lifting/shortening phase. Usually performed forcefully/explosively.
ROM (Range of Motion)How far the muscle travels through a rep. Reaching the deep, stretched portion matters most — the stretch beats the squeeze.
Long-Muscle-Length BiasFavoring exercises that load the muscle while it's stretched (e.g. Bayesian cable curl, DB Bulgarian split squat). Loading at long lengths drives more growth.
LLPs (Long-Length Partials)Partial reps performed in the stretched portion of a lift — often used to extend a set past failure.
Myo-repsExtending a set beyond failure with short (~5s) mini-rests, squeezing out 3–4 extra reps each round until you can't get 3. Captures more effective reps.
Static Stretch (intensity technique)Holding a fixed stretch after the last set. Used for calves only here — a ~30s hold per calf.
Intensity TechniqueA method applied to the last set to push past normal failure (failure, LLPs, myo-reps, static stretches).
Mind-Muscle ConnectionConsciously feeling the target muscle work. Improving it can increase hypertrophy, especially on isolation work.
Stimulus-to-Fatigue Ratio (SFR)How much growth stimulus an exercise delivers relative to the systemic fatigue it costs. The program favors high-SFR machine/cable choices.
VolumeTotal hard work for a muscle, usually counted as working sets per week. Ramps up across the second block.
Deload / Intro WeekA reduced-effort week (Weeks 1 & 6) to learn lifts and shed accumulated fatigue. Sets stop short of failure.
Training BlockA multi-week phase with a consistent set of exercises. This program runs a 5-week Foundation block and a 7-week Ramping block.
SplitHow muscle groups are divided across training days. This program uses Upper / Lower / Pull / Push / Legs, 5× per week.
Maintenance CaloriesThe daily calorie intake at which bodyweight stays stable — the baseline for setting a surplus (bulk) or deficit (cut).
Recomp (Recomposition)Building muscle and losing fat at roughly the same time, typically near maintenance calories.
