Phase 2: Program Architecture

Periodization Models

| Model | Best For | Structure | When to Use | |-------|---------|-----------|-------------| | Linear | Beginners | Increase load weekly | First 6-12 months | | Undulating (DUP) | Intermediate | Vary rep ranges within week | Stalling on linear | | Block | Advanced | 3-4 week focused blocks | Peaking for competition | | Conjugate | Advanced strength | Max effort + dynamic effort rotation | Powerlifting focus | | Hybrid periodization | Hybrid athletes | Concurrent strength + cardio blocks | Hyrox, CrossFit, OCR |

Training Split Selection

| Split | Frequency | Best For | Sessions/Week | |-------|-----------|---------|---------------| | Full Body | 3x/week | Beginners, time-limited | 3 | | Upper/Lower | 4x/week | Intermediates, balanced | 4 | | Push/Pull/Legs | 5-6x/week | Intermediates-advanced, hypertrophy | 5-6 | | Bro Split | 5x/week | Advanced bodybuilding | 5 | | Upper/Lower + Conditioning | 5x/week | Hybrid athletes | 3 lifting + 2 conditioning | | Concurrent | 5-6x/week | Hyrox/OCR/CrossFit | Mixed daily |

Selection Rules: 1. Beginners: Full body 3x/week. Always. 2. If <4 days available: Full body or upper/lower 3. If hypertrophy focus: PPL or upper/lower for volume 4. If hybrid/endurance: Upper/lower + dedicated conditioning days 5. Recovery capacity determines frequency — more isn't always better

Phase 3: Exercise Selection & Programming

Movement Pattern Requirements

Every program MUST include these patterns weekly:

| Pattern | Primary Exercises | Alternatives (limited equipment) | |---------|------------------|----------------------------------| | Horizontal Push | Bench press, dumbbell press | Push-ups, floor press | | Horizontal Pull | Barbell row, cable row | Inverted rows, resistance band rows | | Vertical Push | Overhead press, dumbbell shoulder press | Pike push-ups, handstand push-ups | | Vertical Pull | Pull-ups, lat pulldown | Band pull-ups, doorframe rows | | Squat | Back squat, front squat, goblet squat | Pistol squats, Bulgarian split squats | | Hinge | Deadlift, Romanian deadlift, hip thrust | Single-leg RDL, KB swings | | Carry/Core | Farmer walks, pallof press, hanging leg raise | Plank variations, dead bugs | | Lunge/Single-leg | Walking lunges, step-ups | Bodyweight lunges, single-leg glute bridge |

Rep Range Guide

| Goal | Reps | Sets/Exercise | Rest | RPE Target | |------|------|--------------|------|------------| | Strength | 1-5 | 3-5 | 3-5 min | 8-9.5 | | Hypertrophy | 6-12 | 3-4 | 60-120 sec | 7-9 | | Muscular endurance | 12-20+ | 2-3 | 30-60 sec | 7-8 | | Power | 1-5 | 3-5 | 3-5 min | 7-8 (explosive) |

RPE Scale Reference

| RPE | Description | Reps in Reserve | |-----|-------------|----------------| | 10 | Maximum effort, cannot do another rep | 0 RIR | | 9 | Could maybe do 1 more | 1 RIR | | 8 | Could do 2 more | 2 RIR | | 7 | Could do 3 more, moderate effort | 3 RIR | | 6 | Light, warmup weight feel | 4+ RIR |

Progressive Overload Methods (Priority Order)

1. Add reps — Hit top of rep range? Add 1-2 reps next session 2. Add weight — Hit top of rep range for all sets? Add 2.5-5 kg 3. Add sets — Within weekly volume targets? Add 1 set 4. Increase ROM — Deficit deadlifts, paused squats, deeper squats 5. Decrease rest — Only for conditioning/endurance goals 6. Increase tempo — Slower eccentrics (3-4 sec) for hypertrophy 7. Increase frequency — Train muscle group more often within recovery limits

Weekly Volume Landmarks (Sets Per Muscle Group Per Week)

| Muscle Group | MEV (Minimum) | MAV (Maximum Adaptive) | MRV (Maximum Recoverable) | |-------------|---------------|----------------------|--------------------------| | Chest | 8 | 12-16 | 20-22 | | Back | 8 | 12-18 | 20-25 | | Shoulders | 6 | 10-14 | 18-20 | | Quads | 6 | 10-16 | 18-20 | | Hamstrings | 4 | 8-12 | 14-16 | | Biceps | 4 | 8-14 | 16-20 | | Triceps | 4 | 8-12 | 14-18 | | Glutes | 4 | 8-14 | 16-20 | | Calves | 6 | 10-14 | 16-20 | | Abs | 0 | 6-10 | 14-16 |

Rules:

Start at MEV, add 1-2 sets/muscle/week across mesocycle

When gains stall, check if approaching MRV (fatigue masking gains)

Deload resets fatigue — return to MEV and progress again

Compounds count toward multiple muscle groups (bench = chest + triceps + shoulders)

Phase 5: Running & Cardio Programming

Heart Rate Zones

| Zone | % Max HR | RPE | Purpose | Duration | |------|---------|-----|---------|----------| | Zone 1 | 50-60% | 2-3 | Recovery, warmup | Unlimited | | Zone 2 | 60-70% | 4-5 | Aerobic base (80% of training) | 30-90+ min | | Zone 3 | 70-80% | 6-7 | Tempo, threshold | 20-40 min | | Zone 4 | 80-90% | 8-9 | VO2max intervals | 3-8 min intervals | | Zone 5 | 90-100% | 10 | Sprint, anaerobic | 10-60 sec intervals |

Max HR estimate: 220 - age (rough) or 208 - (0.7 × age) (more accurate)

80/20 Rule

80% of running volume in Zone 1-2 (easy, conversational pace)

20% in Zone 3-5 (hard efforts)

Violating this is the #1 mistake recreational runners make

Easy runs should feel embarrassingly slow

Running Progression Rules

1. 10% rule: Increase weekly mileage by max 10%/week 2. 3-week build, 1-week back: Build for 3 weeks, reduce 20-30% on 4th 3. Long run: Max 30% of weekly volume in one run 4. Easy pace test: Can hold full conversation? That's Zone 2. 5. Speed work: Only after 4+ weeks of consistent base building

Conditioning Modalities for Hybrid Athletes

| Modality | Muscles | Cardio Benefit | Joint Impact | Hyrox Relevance | |----------|---------|---------------|-------------|----------------| | Running | Legs, core | High | High | Direct — 8km total | | Rowing | Full body | High | Low | Direct — 1000m station | | Ski Erg | Upper body, core | High | None | Direct — 1000m station | | Assault Bike | Full body | Very high | None | Cross-training | | Swimming | Full body | High | None | Active recovery | | Cycling | Legs | Moderate-high | None | Zone 2 alternative |

Phase 6: Recovery & Fatigue Management

Recovery Priority Stack

| Priority | Method | Impact | Cost | Time | |----------|--------|--------|------|------| | 1 | Sleep 7-9 hours | ★★★★★ | Free | 7-9h | | 2 | Protein 1.6-2.2g/kg | ★★★★★ | $$ | N/A | | 3 | Hydration 35-45ml/kg | ★★★★ | Free | N/A | | 4 | Deload weeks | ★★★★ | Free | 1 week/4-6 | | 5 | Active recovery (Zone 1) | ★★★ | Free | 20-40 min | | 6 | Mobility/stretching | ★★★ | Free | 10-15 min | | 7 | Foam rolling | ★★ | $ | 10-15 min | | 8 | Cold exposure | ★★ | $ | 2-5 min | | 9 | Massage | ★★ | $$$ | 60 min | | 10 | Compression garments | ★ | $$ | Wear post-session |

Rules:

Never sacrifice #1-4 for #5-10

Cold water immersion: useful for acute recovery between competitions, may blunt hypertrophy if used chronically post-strength training

Foam rolling: pre-workout for mobility, post-workout for parasympathetic activation

Sleep is the #1 performance enhancer. Period.

Fatigue Monitoring

daily_readiness:
  date: "YYYY-MM-DD"
  sleep_hours: 0
  sleep_quality: "1-5"  # 1=terrible, 5=great
  resting_hr: 0  # check first thing in morning
  hrv: 0  # if tracking
  muscle_soreness: "1-5"  # 1=none, 5=severe
  mood_energy: "1-5"  # 1=exhausted, 5=fired up
  motivation: "1-5"
  
  readiness_score: 0  # sum of quality+soreness(inverted)+mood+motivation = /20
  
  decision:
    # 16-20: Full intensity, push hard
    # 12-15: Normal training
    # 8-11: Reduce intensity or volume by 20%
    # 4-7: Active recovery or rest day

Deload Protocol

| Component | Normal Week | Deload Week | |-----------|------------|-------------| | Volume (sets) | 100% | 50-60% | | Intensity (weight) | Normal | Same or slightly reduce | | Frequency | Normal | Same | | Cardio volume | Normal | 50-70% | | Duration | Normal | Shorter sessions |

When to deload:

Planned: Every 4th week (intermediate), every 6-8th week (beginner)

Reactive: 2+ sessions where RPE is higher than expected for same weight

Sleep declining, motivation dropping, joint aches increasing

Performance plateau for 2+ weeks despite adequate nutrition/sleep

Phase 7: Nutrition for Training

Calorie & Macro Targets

Maintenance TDEE estimate:

Sedentary: BW(kg) × 26-28

Lightly active (3x/week): BW(kg) × 30-32

Active (5x/week): BW(kg) × 34-36

Very active (6x+ hard training): BW(kg) × 38-42

Goal-based adjustments: | Goal | Calorie Adjustment | Protein | Carbs | Fat | |------|-------------------|---------|-------|-----| | Muscle gain | +300-500 cal | 1.6-2.2 g/kg | 4-7 g/kg | 0.8-1.2 g/kg | | Fat loss | -300-500 cal | 2.0-2.4 g/kg | 2-4 g/kg | 0.7-1.0 g/kg | | Maintenance | 0 | 1.6-2.0 g/kg | 3-5 g/kg | 0.8-1.2 g/kg | | Endurance heavy | +200-400 cal | 1.4-1.8 g/kg | 5-8 g/kg | 0.8-1.0 g/kg | | Hybrid (Hyrox) | +0-300 cal | 1.8-2.2 g/kg | 4-6 g/kg | 0.8-1.0 g/kg |

Pre/Intra/Post Workout Nutrition

| Timing | What | Why | |--------|------|-----| | 2-3h pre | Balanced meal (protein + carbs + fat) | Sustained energy | | 30-60 min pre | Small snack (carbs + small protein) | Quick fuel, no GI distress | | Intra (>60 min session) | 30-60g carbs/hour (sports drink, banana) | Maintain blood glucose | | 0-2h post | Protein (30-40g) + carbs (0.8-1g/kg) | Recovery, glycogen replenishment |

Supplements (Evidence-Based Only)

| Supplement | Dose | Evidence | When | |-----------|------|----------|------| | Creatine monohydrate | 3-5g daily | ★★★★★ | Any time, every day | | Caffeine | 3-6 mg/kg | ★★★★★ | 30-60 min pre-workout | | Protein powder | As needed to hit target | ★★★★ | Convenience — whole food first | | Vitamin D | 1000-4000 IU daily | ★★★★ | If deficient (most people in UK) | | Omega-3 (EPA/DHA) | 1-3g daily | ★★★ | Anti-inflammatory | | Magnesium | 200-400mg daily | ★★★ | Sleep quality, recovery | | Electrolytes | During long sessions | ★★★ | Sessions >60 min, hot weather |

Don't waste money on: BCAAs (if eating enough protein), testosterone boosters, fat burners, most pre-workout ingredients beyond caffeine.

Common Issue Prevention

| Issue | Cause | Fix | |-------|-------|-----| | Low back pain | Weak core, hip tightness, poor bracing | McGill Big 3, hip flexor stretching, bracing drills | | Shoulder impingement | Internal rotation dominance, weak rotator cuff | Face pulls, band external rotations, reduce overhead volume | | Knee pain (anterior) | Quad dominance, weak VMO, poor ankle mobility | Terminal knee extensions, ankle dorsiflexion work, step-downs | | Elbow tendinitis | Grip/wrist overuse, sudden volume increase | Wrist curls, eccentric work, reduce isolation curl volume | | Hip shift in squat | Adductor/abductor imbalance, ankle restriction | Cossack squats, banded squats, heel elevation |

When to See a Professional

Sharp pain during or after exercise (not muscle soreness)

Swelling that doesn't resolve in 48 hours

Numbness or tingling

Loss of range of motion lasting >2 weeks

Pain that worsens with each session

Any injury that changes your movement pattern

Phase 10: Plateaus & Troubleshooting

Plateau Decision Tree

Strength stalling?
├─ Eating enough? (surplus for gain, maintenance minimum)
│  └─ No → Fix nutrition first
├─ Sleeping 7+ hours?
│  └─ No → Fix sleep first
├─ Been training >4 weeks without deload?
│  └─ Yes → Deload, then reassess
├─ Same program >12 weeks?
│  └─ Yes → Change program (new stimulus)
├─ Volume too high? (approaching MRV)
│  └─ Yes → Reduce volume, increase intensity
├─ Volume too low? (at MEV)
│  └─ Yes → Add 1-2 sets/muscle/week
└─ All good? → Change rep range or exercise variation

Common Mistakes

| # | Mistake | Fix | |---|---------|-----| | 1 | No progressive overload (same weight every week) | Log every session, aim to beat last performance | | 2 | Program hopping (new program every 2 weeks) | Stick to a program for minimum 8-12 weeks | | 3 | Junk volume (30+ sets/muscle, half-effort) | Do fewer sets at higher effort (RPE 7-9) | | 4 | Skipping legs | Follow balanced split — legs are 50%+ of your body | | 5 | Never deloading | Schedule deloads, or take reactive deloads when signs appear | | 6 | Ego lifting (too heavy, bad form) | Drop weight 20%, master form, then rebuild | | 7 | Cardio killing gains | Separate cardio from lifting by 6+ hours, or do after lifting | | 8 | Not eating enough protein | 1.6-2.2 g/kg — track for 2 weeks to calibrate | | 9 | Ignoring sleep | 7-9 hours non-negotiable — it's when you grow | | 10 | All intensity, no technique work | Record yourself, get form checks, invest in one coaching session |

Phase 11: Body Composition Strategies

Fat Loss Protocol

1. Set deficit: -300 to -500 cal/day (1% BW loss/week max) 2. Protein HIGH: 2.0-2.4 g/kg (muscle preservation is priority #1) 3. Training: Maintain intensity (heavy weights), reduce volume slightly if recovery drops 4. Cardio: Add 2-3 sessions of Zone 2 (walks, easy cycling), LISS > HIIT for sustainability 5. Step target: 8,000-12,000 steps/day (NEAT is the biggest calorie lever) 6. Timeline: Aim for 8-16 week cut, then 4+ weeks maintenance 7. Refeed: 1 day/week at maintenance with extra carbs if sub-15% BF 8. When to stop: Reaching target BF%, performance declining, diet fatigue >8/10

Muscle Gain Protocol

1. Set surplus: +200-500 cal/day (0.5-1% BW gain/month for intermediates) 2. Protein adequate: 1.6-2.2 g/kg 3. Training: High volume focus (MAV range), progressive overload 4. Cardio: Minimal but maintain cardiovascular health (2x Zone 2, 20-30 min) 5. Timeline: Bulk for 12-20 weeks, then maintain or mini-cut 6. When to stop: BF% exceeding comfort (usually >18-20% men, >28-30% women), or at planned timeline

Body Recomposition (Lose Fat + Gain Muscle)

Who it works for:

Beginners (first 6-12 months)

Detrained athletes returning

Overweight beginners (higher BF% = more recomp potential)

NOT effective for lean intermediates/advanced

How: Eat at maintenance, high protein (2.0+ g/kg), train hard with progressive overload. Trust the process — scale may not move but body composition changes.

Phase 12: Competition & Race Prep

Taper Protocol (Final 1-2 Weeks)

| Variable | 2 Weeks Out | 1 Week Out | 2 Days Out | Race Day | |----------|-------------|------------|------------|----------| | Volume | -30% | -50% | -70% | Race | | Intensity | Maintain | 1-2 race pace efforts | Easy only | Race effort | | Frequency | Normal | -1 session | Light movement | Race | | Carbs | Normal | Slightly increase | Carb load (+2g/kg) | Race morning meal | | Sleep | Priority | 8+ hours | 8+ hours (expect nerves) | Up early enough |

Race Day Checklist

race_day:
  morning:
    - Wake 3-4 hours before start
    - Familiar breakfast (tested in training)
    - Light caffeine if used in training
    - Kit check: shoes, watch, nutrition, number
    - Arrive 60-90 min before start
  
  warmup:
    - 10-15 min easy jog
    - Dynamic stretches
    - 2-3 race pace strides
    - Station-specific warmup (light ski erg pulls, bodyweight lunges)
  
  race_strategy:
    - Negative split: start conservative, build through middle, push final 2km
    - Station pacing: steady effort, don't redline early
    - Nutrition: sports drink/gel every 30-45 min
    - Mental cues: "relax, breathe, one station at a time"
  
  post_race:
    - Walk/easy movement for 10-15 min
    - Protein + carbs within 30 min
    - Rehydrate
    - Celebrate
    - Review within 24-48 hours while fresh

10 Training Commandments

1. Progressive overload or you're exercising, not training 2. Sleep is when you grow — protect it like your job depends on it 3. Protein is the only macro that MUST hit target daily 4. Consistency beats intensity — 80% effort for 52 weeks > 100% for 4 5. Track everything — what gets measured gets managed 6. Deload before you need to — proactive beats reactive 7. Ego is the enemy — perfect form at moderate weight beats ugly maxes 8. Specificity matters — train for YOUR goal, not someone else's program 9. Recovery is training — the workout is the stimulus, rest is the adaptation 10. Long game wins — think in years, not weeks

10 Common Training Mistakes

| # | Mistake | Impact | Fix | |---|---------|--------|-----| | 1 | No program (winging it) | Zero progression | Pick a program and follow it 8-12 weeks | | 2 | All cardio, no strength | Skinny-fat, injuries | Add 2-3 strength sessions/week minimum | | 3 | Running too fast on easy days | Overtraining, injury | Use HR monitor — Zone 2 should feel easy | | 4 | Skipping warmup | Injury risk, worse performance | 10 min: cardio + dynamic stretching + ramping sets | | 5 | Only training what you like | Imbalances, injury | Program ALL movement patterns | | 6 | Copying advanced athletes | Overtraining, frustration | Match program to YOUR training age | | 7 | Relying on motivation | Inconsistency | Build habits, schedule sessions like meetings | | 8 | Comparing to others | Discouragement | Track YOUR progress over months | | 9 | Ignoring pain signals | Chronic injury | Sharp pain = stop, get assessed | | 10 | Overcomplicating everything | Analysis paralysis | Simple program + consistency = 90% of results |

Edge Cases

Coming Back After Injury

Start at 50% of previous weights

Build back over 4-6 weeks

Any exercise that causes pain gets swapped

See physio for clearance before returning to sport

Training Over 40

Recovery takes longer — 3-4x/week often optimal

Joint-friendly variations (trap bar deadlift, DB press)

Warmup becomes non-negotiable

Mobility work daily

Prioritize eccentric control over heavy maxes

Training in a Home Gym (Minimal Equipment)

DB + bench + pull-up bar covers 90% of needs

Resistance bands for rotator cuff and face pulls

Adjustable DBs > fixed set (space + cost efficient)

Priority buys: adjustable DBs → bench → pull-up bar → barbell + plates → rack

Training + Shift Work

Train after longest sleep block

Keep schedule consistent on work days

Caffeine cut-off 6h before sleep

Meal prep is essential — no time for decisions

Beginner Who's Afraid of the Gym

Start with 2 weeks of bodyweight at home

Go once to just walk around and do cardio

Bring a program on your phone — purpose reduces anxiety

Early morning or late evening = quieter

Everyone started somewhere. Nobody is watching you.
