01 — The Problem
Strength training programs for tactical and athletic populations are built for healthy central nervous systems. Programs peak at 90-95% of training max with singles and doubles — demanding maximal CNS output, heavy Valsalva, and rapid autonomic recovery between sets.
For individuals with TBI history, this creates specific and measurable problems:
- CNS demand exceeds what a recovering nervous system can safely handle
- Valsalva maneuver at near-maximal loads spikes intracranial pressure (ICP)
- Exertion-related symptoms: headaches, dizziness, vision disturbances, cognitive fog
- Autonomic dysregulation — the body's automatic systems (heart rate, blood pressure, breathing) don't respond normally, altering exercise recovery capacity
The result: people either avoid heavy training entirely (losing strength and capability) or push through symptoms with no framework (risking setback). There is no structured, evidence-based strength program designed for this population.
DarkWolf changes that.
02 — The DarkWolf Approach
DarkWolf takes proven strength training template structures and applies evidence-based modifications that respect neurological constraints while preserving meaningful strength development.
Core Modifications:
- Percentage ceilings: 85% TM maximum (Ghost peaks at 80%)
- Rep floors: Minimum 3 reps per set — no singles or doubles, ever
- Neuro-RPE governance: Dual-track autoregulation integrating muscular effort AND neurological symptoms
- Volume adjustments: Higher rep ranges to compensate for lower intensity
- Extended rest periods: 3-5 minutes for autonomic recovery
- Mandatory deload: Every 4th week, non-negotiable
- Symptom-based autoregulation: Decision trees for adjusting within a session
- 48-Hour Rule: If neurological symptoms persist 48+ hours post-session, the next session becomes a deload
03 — Training Max System
All DarkWolf programs use the Training Max (TM) system. You never test a true 1-rep max.
Step 1: Find a Recent Working Set
Use a recent set performed at RPE 7-8 (2-3 reps left in the tank). Record the weight and reps.
Step 2: Estimate Your 1RM
Example: 225 lbs × 5 reps = 225 × 1.167 = ~260 lbs estimated 1RM
Step 3: Calculate Training Max
Example: 260 × 0.90 = ~235 lbs TM (rounded to nearest 5 lbs)
Step 4: All Percentages Are Based on TM
When the program says "70% TM," you calculate 70% of 235 = ~165 lbs. This is your working weight for that week.
04 — Neuro-RPE Scale
Standard RPE tracks muscular effort only. The DarkWolf Neuro-RPE scale is a dual-track system that integrates neurological symptoms alongside muscular effort. The higher score always governs the session.
| Score | Muscular Effort | Neurological Status | Zone | Action |
|---|---|---|---|---|
| 1-4 | Light to moderate | Clear. No symptoms. | GREEN | Continue as prescribed |
| 5-6 | Moderate. 4+ reps in reserve. | Clear. Slight fatigue. | GREEN | Target zone for volume days |
| 7 | Mod-hard. 3 reps in reserve. | Mild head pressure, warmth. | YELLOW | Extend rest to 4+ min. Do not increase load. |
| 8 | Hard. 2 reps in reserve. | Head pressure, mild headache, slight dizziness. | ORANGE | Peak intensity only. Consider ending main work. |
| 9 | Very hard. 1 rep in reserve. | Headache, dizziness, visual disturbance, fog. | RED | STOP. Reduce load 10-15% or end main work. |
| 10 | Maximal. | Sharp headache, nausea, disorientation. | BLACK | TERMINATE SESSION. Rest 48+ hrs. Consult provider. |
Pre-Session Protocol:
- No symptoms: Proceed as prescribed
- Mild symptoms (background headache, slight fog): Drop all percentages by 5% TM, extend rest +1 min
- Moderate symptoms (active headache, dizziness): Recovery session only or rest day
- Severe symptoms: Rest day. Consult provider if new or worsening.
05 — Ghost Protocol
GHOST PROTOCOL
Ghost is the foundation template. Lowest peak intensity (80% TM), maximum room for conditioning. If you're new to DarkWolf or returning to structured training after TBI, start here. All main lifts (2-3) performed every session. Spread evenly (e.g., Mon/Thu), never back-to-back.
| Week | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Sets × Reps | 4×5 | 4×5 | 3×5 | 2×5 | 4×5 | 4×5 | 3×5 | 2×5 |
| % of TM | 70% | 75% | 80% | 60% | 70% | 75% | 80% | 60% |
| RPE Cap | 6 | 6 | 7 | 5 | 6 | 6 | 7 | 5 |
| Rest (min) | 3 | 3 | 3-4 | Any | 3 | 3 | 3-4 | Any |
| Type | Volume | Volume | Moderate | Deload | Volume | Volume | Moderate | Deload |
06 — Sentinel Protocol
SENTINEL PROTOCOL
Sentinel increases the intensity ceiling to 85% TM with sets of 3. For experienced lifters who have completed 2-3 Ghost cycles and want to push strength development while maintaining TBI safety protocols. All main lifts (2-3) every session. Schedule every other day (e.g., Mon/Wed/Fri).
| Week | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Sets × Reps | 4×5 | 4×5 | 3×3 | 2×5 | 4×5 | 4×5 | 3×3 | 2×5 |
| % of TM | 70% | 80% | 85% | 60% | 75% | 80% | 85% | 60% |
| RPE Cap | 6 | 7 | 8 | 5 | 6 | 7 | 8 | 5 |
| Rest (min) | 3 | 3-4 | 4-5 | Any | 3 | 3-4 | 4-5 | Any |
| Type | Volume | Moderate | Intensity | Deload | Volume | Moderate | Intensity | Deload |
07 — Ironhide Protocol
IRONHIDE PROTOCOL
Ironhide is the mass-building template. A/B alternating split with 6 lifts over 12 weeks, plus accessory work (up to 3 per session, giant sets, 3-4 × 8-12). For lifters who want to add size alongside strength while respecting TBI constraints. Non-consecutive days (e.g., Mon/Wed/Fri).
| Week | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Sets × Reps | 4×6 | 4×5 | 3×3 | 2×5 | 4×6 | 4×5 | 3×3 | 2×5 | 4×6 | 4×5 | 3×5 | 2×5 |
| % of TM | 70% | 80% | 85% | 60% | 75% | 80% | 85% | 60% | 75% | 80% | 85% | 60% |
| RPE Cap | 6 | 7 | 8 | 5 | 6 | 7 | 8 | 5 | 6 | 7 | 8 | 5 |
| Rest (min) | 3 | 3-4 | 4-5 | Any | 3 | 3-4 | 4-5 | Any | 3 | 3-4 | 4-5 | Any |
| Type | Volume | Mod | Intensity | Deload | Volume | Mod | Intensity | Deload | Volume | Mod | Intensity | Deload |
Week 11 uses 5 reps at 85% (not triples) as the final intensity push.

09 — Conditioning Integration
Strength and conditioning should complement each other, not compete. For TBI populations, both must deload simultaneously — unlike standard programming that alternates.
Ghost Protocol:
- Maximum conditioning freedom — 4-5 days available
- Pair with base building or green conditioning
- Can run full endurance sessions on off-days
Sentinel Protocol:
- Moderate conditioning — 2-3 sessions/week
- Pair with Black protocol conditioning
- Easy conditioning on intensity weeks (weeks 3, 7)
Ironhide Protocol:
- Minimal conditioning — max 2 HIC sessions/week
- No endurance work (interferes with mass building)
- Focus is on recovery and growth
10 — Session Logging
Tracking sessions is essential for TBI-adapted training. Unlike standard training logs that only record weight and reps, DarkWolf logs include neurological data that drives autoregulation decisions.
What to Log:
- Date and week number
- Pre-session symptoms (baseline before training)
- Sleep quality (1-10) — poor sleep amplifies neurological symptoms
- Exercise, weight, sets × reps
- Neuro-RPE per set (both muscular and neurological scores)
- Intra-session symptoms (what appeared during training)
- Post-session symptoms (2 hours after)
- Notes — stress, hydration, medication changes
Over time, your log reveals patterns: which lifts trigger symptoms, which weeks are hardest, how sleep affects training tolerance. This data is invaluable for adjusting future cycles.
Session Log Template:
| Date | Wk | Pre-Symptoms | Sleep | Exercise | Weight | Sets×Reps | N-RPE | Intra-Symptoms | Post (2hr) | Notes |
|---|---|---|---|---|---|---|---|---|---|---|
11 — Cycle-to-Cycle Progression
Progression in DarkWolf is conservative and deliberate. You are not chasing 1RM PRs.
Between Cycles:
- Add 5 lbs to upper body Training Max values
- Add 5 lbs to lower body Training Max values
- Same increment regardless of template
When to Hold:
If you hit Neuro-RPE 8+ on more than 2 sessions in a cycle, do NOT increase TM for the next cycle. Repeat at the same TM until your neurological tolerance improves.
When to Reduce:
If the 48-Hour Rule triggered more than twice in a cycle, reduce TM by 5-10% and repeat. This is not failure — it's intelligent autoregulation.
