postIt cannot slim a body part directly. Spot reduction does not exist. Calf/trap size = muscle + fat on top + bone geometry; only the fat part moves, and only systemically.
What it does: stops growing the muscle underneath, rebalances the scapula so the neck-shoulder line reads longer, restores ankle range. The trap win is mostly postural.
Limit: calf belly length is fixed. Some of your calf shape isn't modifiable by anything here.
Long static stretching GROWS muscle — the opposite of the obvious assumption. Sports Medicine – Open 2024 meta-analysis: hypertrophy only at ≥15 min/session AND ≥5×/wk AND >6 weeks (d=0.28). Under 15 min/session: not significant (d=0.13, p=0.14). Warneke used a calf orthosis 1–2 h/day.
So 2 min/day = size-neutral, free range-of-motion. An hour a day would work against you. Never extend this block.
Your Saturday TBC stretching hour stays — 1–2× per month is far below the frequency threshold.
The programme file tbc_program.js is untouched — it stays a faithful transcription of the PDF. These swaps live in tbc_swaps.js and are applied when the tracker renders a session. Set window.TBC_SWAPS.enabled = false to revert all four at once.
| Was | Now | Why |
|---|---|---|
| Heel raise (2×6 kg) — 2 min 9× across weeks 3–11 |
Glute bridge (2×6 kg) — 2 min | The one unambiguously targeted calf-growth exercise in the plan, and the only one with no conditioning benefit to trade away. Cheapest possible cut. |
| 20× / 30× / 35× 1 min jump rope weeks 8–11 |
capped at 10× 1 min | Rope is kept — it is the highest energy expenditure per minute in the week, and systemic fat loss is the only thing that can actually reduce calf circumference. The problem was never rope, it was the dose spike: 20–35 min of continuous plyometrics in one session. Sessions already at or under 10× are untouched. |
| Arm elevation — 2–3 min | + stop at shoulder height, shoulders DOWN | Upper-trap activation climbs steeply once the arm passes 90°, because the scapula must elevate to continue. Load and duration unchanged — only range and cue, so the deltoid work survives. |
| 5× (2 min fast / 2 min slow) etc. 7 interval sessions |
steady moderate run, same total duration + flat ground, no incline |
Sprinting and hills are the running equivalent of plyometrics for the soleus. Total cardio minutes preserved. Cost, stated plainly: this removes your cardio progression — steady-state only means VO₂max gains plateau earlier than the programme intends. |
Deliberately NOT changed: jump squats and jump lunges — they are the programme's main glute-and-thigh work, which is what you actually want to build; plantar flexion there is incidental. And the Saturday stretching hour, per the dose reasoning above.
Exercise selection for Block A (prone Y, wall slide, scapular depression) follows the standard lower-trap / serratus-anterior surface-EMG literature, which ranks these highly for lower-trap and serratus activation relative to upper trap. The primary JOSPT paper (Ekstrom / Ludewig line of work) returned 403 to automated fetching on 2026-07-30 — flagged rather than cited as verified.
