Strength Reserve — Build Extra Muscle So Life Feels Lighter


⏱️ Time Horizon: 28‑day foundation (then maintain 2×/wk)
📍 Ideal For: Cardio‑only trainees, chronic fatigue despite “good labs,” injury‑prone joints, or anyone who wants to age like they have a cheat code.

Deeper Work = Tissue Banking.
Muscle is functional savings—it buffers glucose, props up metabolism, secretes mood‑boosting myokines, and protects joints. We’re not chasing bodybuilding trophies; we’re stockpiling contractile currency so everyday tasks cost fewer ATP dollars.

28‑Day Strength Reserve Blueprint

Phase I — Baseline & Movement Literacy (Days 1–3)


  1. Strength Screen: Max reps in 60 sec — bodyweight squat, push‑up (elevate hands if needed), plank hold time, chair stand.

  2. Mobility Quick‑Check: Overhead reach (thumbs to wall), ankle dorsiflexion (knee‑to‑wall test).

  3. Load Audit: Identify at‑home implements—dumbbells, kettlebell, backpack with books.

Phase II — Neuromuscular Activation (Days 4–10)


Goal: Groove patterns at RPE 5/10.
Day Session Prescription
4 Full‑Body A Goblet Squat 3×8, Incline Push‑up 3×8, Hip Hinge (band) 3×10
5 Isometric Core Front Plank 3×30 sec, Side Plank 3×20 sec/side
6 Restorative Walk 30 min nasal‑only walk
7 Full‑Body B Split Squat 3×8/leg, Bent‑Over Row 3×8, Carry 3×30 m
8 Mobility Flow 10 min hip / T‑spine sequence
9 Repeat A Same as Day 4; focus on form
10 Rest

Phase III — Progressive Overload (Days 11–24)


Goal: Add load or reps 5 % each session; RPE 7–8.

  • Schedule: 3 full‑body sessions per week (e.g., Mon‑Wed‑Fri).

  • Scheme: 3–4 exercises × 3 sets × 6–10 reps.

  • Progression Ladder: When you hit 10 reps on all sets, raise weight next session.

  • Movement Menu: Squat pattern, Hip Hinge, Horizontal Push, Horizontal Pull, Loaded Carry.

  • Optional Finishers: 2‑min max‑rep kettlebell swing or air‑squat for conditioning hit.

Phase IV — Reserve Test & Lock‑In (Days 25–28)


  1. Re‑Test Baseline: Repeat strength screen; aim ≥30 % rep gain or ≥20 sec longer plank.

  2. Grip Strength Check: Cheap dynamometer or max plate pinch 30 sec.

  3. Auto‑Pilot Plan: Schedule 2 strength sessions/week, book recurring calendar invite.

  4. Reflection Entry: Subjective energy vs. Day 1; note posture, joint comfort, confidence.


Metrics & Tracking Dashboard


  • Strength Index: Sum of reps across screen moves; target +30 %.

  • Grip Strength: ≥5 kg increase or hold weight 10 % heavier for same time.

  • RPE Accuracy: Session RPE within ±1 of plan 80 % of time.

  • Energy Score: +2 points vs. baseline.

Completion Criteria


✔️ Strength index +30 % from baseline.
✔️ Grip or pinch strength improved.
✔️ Able to perform 3×10 goblet squats @ ≥25 % bodyweight.
✔️ Subjective energy & physical confidence ≥8/10 two days running.


Field Notes & Troubleshooting


  • “Equipment‑Free?” Use backpack loaded with books, water jugs, or resistance bands.

  • Recovery Lag? Prioritise protein (1.6 g/kg) & Sleep Credit Check module.

  • Pain Signals? Regress to isometrics or shorten range until pain‑free.
