A fourth weekly session built entirely around glutes and shoulder cap, isolation work pushed closer to real failure, and the same double-progression rule Foundation already taught you — once two sessions a week of Foundation’s own rep ceilings have stopped feeling hard.
Just graduating from Foundation? Read the new fourth session and what changed on the other three below. Where this fits in the whole track
Already lifting, looking for the actual numbers? Jump straight to the new session and the volume increase behind it. Day C, the new glute-and-shoulder session · Why four days, not five
Foundation’s own reasoning put three sessions a week at the bottom of the ACSM position stand’s novice bracket (“roughly 2-3 days a week”), on purpose, for a track built first for someone with no barbell experience at all. Two sessions a week of Foundation’s own rep-range ceilings (see Foundation’s own progression rule) becoming genuinely easy is the honest signal that work capacity, not just familiarity, has actually grown — Foundation’s own closing section named this exact signal as the real gate to Growth. The real next step on the same ACSM ladder is the bottom of its intermediate-to-advanced bracket, “3-4 days a week,” not straight to its own top end.
Bikini’s own Growth phase moves from four days to five, adding a dedicated glute-finisher session, because Bikini’s own Foundation already started at four — a division-specific program built for someone who already has basic gym literacy going in. Tone and Truth’s own Foundation starts one session lower, at three, specifically because it can’t assume that. Copying Bikini’s exact jump here would mean asking someone who was training zero days a week not long ago to suddenly train five — a real, checked mismatch with who this track is actually built for. Four sessions a week, one step up from three, is the honest fit: this phase keeps Foundation’s own two-day alternating structure (Day A, Day B) and adds one new session (Day C) rather than Bikini’s full second lower/upper day pair.
| Day | Emphasis | Priority pattern trained directly |
|---|---|---|
| Day A | Squat emphasis | Squat pattern & hip thrust |
| Day B | Hip-hinge emphasis | Hip-hinge pattern & glute isolation |
| Day C (new this phase) | Glute & shoulder-cap finisher | Glute isolation, lateral delt, closer to failure |
The three days rotate continuously — A, B, C, A, B, C — rather than repeating on fixed calendar days, the same non-calendar-locked cycling Complete Barbell’s own Build/Groove/Test clock already uses for a different reason (there, three named sessions map cleanly onto three sessions a week; here, three session types spread across four sessions a week, so which day repeats first shifts week to week). That’s disclosed here rather than glossed over: the exact weekly set count below is a per-rotation figure, not a fixed weekly one, because a real week sometimes lands two Day Cs and sometimes one.
Day A and Day B keep Foundation’s own session templates for every slot except the two named below — everything else (equipment substitutions, the double-progression rule) carries over unchanged.
Two slots get a real set increase on both existing days, from 2 sets to 3: Day A’s lateral raise, and Day B’s glute isolation and its own lateral raise. That’s the same real mechanism Bikini’s own Growth phase uses to add volume without adding a full new session on every existing day — the difference here is that most of Growth’s added volume lands on the genuinely new Day C below, not on inflating Day A and Day B further, for the same fatigue-management reason Bikini’s own Growth page gives for spreading load across a new session rather than stacking it onto existing ones.
| Slot | Barbell | No barbell — DB/KB | Cable / full gym | Sets × reps |
|---|---|---|---|---|
| Hip thrust | Barbell hip thrust | DB or single-leg hip thrust, glute bridge | Hip thrust machine | 3 × 10-15 |
| Glute isolation | — (no real barbell equivalent) | Banded lateral walk, side-lying abduction | Cable kickback, hip-abduction machine | 3 × 15-20 |
| Walking lunge / single-leg | — | DB walking lunge | Leg press (single-leg) | 2 × 12-15 |
| Lateral raise (third touch) | — | DB lateral raise | Cable lateral raise | 2 × 15-20 |
| Rear delt / upper back | — | DB rear-delt fly | Cable face pull | 2 × 15-20 |
Over one full pass through Day A, Day B, and Day C, direct glute-max sets run: 3 (Day A hip thrust) + 6 (Day B hip-hinge 3 + isolation 3) + 6 (Day C hip thrust 3 + isolation 3) = 15, and direct lateral-delt sets run: 3 (Day A) + 3 (Day B second touch) + 2 (Day C third touch) = 8 — both a real, deliberate increase from Foundation’s own roughly 12 and 6. Because four sessions a week means one day type repeats before the other two catch up, the plain weekly total sits somewhat above those per-rotation figures rather than at a single fixed number — an honest way to report it, not a fixed weekly count dressed up as more precise than the rotation actually is. Landing above 15 glute-max sets a week comfortably clears the “10+ sets per muscle per week” Schoenfeld, Ogborn & Krieger (2017) category associated with greater hypertrophy — the same citation Bikini’s own Growth phase reuses for the same claim, applied here to a different, independently-arrived-at volume that lands in the same real range because the same research sets both.
Every isolation slot above — glute isolation, lateral raise, rear delt — is meant to be trained close to real muscular failure, the same instruction Schoenfeld, Grgic, Van Every & Plotkin (2021)’s own finding supports directly: a high level of effort, not a specific load or rep number, is what drives hypertrophy across “a wide spectrum of loading ranges.” That’s a real change from Foundation, where the instruction was simply to complete the prescribed reps with reps in reserve — Growth is where “closer to failure” starts actually mattering as its own separate instruction, not just a rep range.
Every slot on every day, including all of Day C, runs the exact same double-progression rule Foundation already taught: climb the rep range set-by-set, session to session, then add a real load increment and restart at the bottom of the range once every set hits the top. Growth adds new exercises and more sets — it doesn’t add a new progression scheme to learn on top of them.
Said plainly: Growth is the second and, so far, last phase of Tone and Truth written. There’s no third phase to link to yet, and no separate programming for the real but rarer male version of this track named on the overview page — both are real, named gaps, not hidden ones. Unlike Bikini’s own arc, this track has no competition to peak toward, so a future third phase (if one is ever built) would look like a further real volume or frequency increase once Growth’s own rep-range ceilings stop feeling hard, not a contest-prep taper — the same open-ended, non-competitive shape this track’s own overview page describes from the start.
