This document outlines fundamental principles of strength training that apply across all experience levels and training goals.

## Progressive Overload

Progressive overload is the cornerstone of strength development. The principle states that to continue making adaptations, training stress must gradually increase over time.

### Methods of Progression

**Volume Progression:**
- Adding sets (e.g., 3 sets → 4 sets)
- Adding reps (e.g., 3x8 → 3x10)
- Most effective for hypertrophy and work capacity

**Intensity Progression:**
- Increasing load (e.g., 100kg → 105kg)
- Most direct for strength gains
- Recommended: 2.5-5kg increases per session for compound lifts

**Frequency Progression:**
- Training a movement pattern more often per week
- Effective for skill acquisition and volume accumulation

### Recommended Progression Timeline

**Beginners (0-1 year):**
- Session-to-session progression possible
- Linear progression protocols effective
- Focus on technique mastery alongside load increases

**Intermediate (1-3 years):**
- Weekly progression more realistic
- Periodization becomes beneficial
- Variation in rep ranges useful

**Advanced (3+ years):**
- Monthly or block-based progression
- Sophisticated periodization necessary
- Autoregulation helps manage fatigue

## Volume

Training volume — sets, reps and load — is a primary driver of both strength and hypertrophy.
Useful weekly ranges, per muscle group:

- **Minimum to progress:** 8–10 sets for major groups, 4–6 for smaller ones.
- **Where most growth happens:** 12–20 sets for major groups, 8–14 for smaller ones.
- **Above recoverable volume:** performance falls, soreness persists, sleep and motivation
  deteriorate. This ceiling is highly individual and moves with sleep, nutrition and life stress.

Volume is the variable to adjust first when progress stalls, and the one to reduce first when
recovery is compromised.

## Exercise Selection and Order

### The order within a session is not arbitrary

Whatever matters most goes first, while the athlete is fresh:

1. **Power or explosive work**, if present. Most sensitive to fatigue.
2. **Primary compound lifts** — squat, hinge, horizontal and vertical press and pull.
3. **Secondary compounds and unilateral work.**
4. **Isolation and accessory work.**
5. **Grip and trunk work last**, because both compromise everything performed after them.

An exercise trained at the end of a session receives less than an exercise trained at the start,
regardless of the sets written next to it. Position in the session is itself a form of prescription.

### Balance across patterns

Over a training week, the programme should cover: knee-dominant and hip-dominant lower body,
horizontal and vertical pushing, horizontal and vertical pulling, and loaded trunk work.

Pulling volume at or above pushing volume is a reasonable default for most people, given how
posterior-chain-poor typical daily activity is.

### Substitution is a legitimate tool

An exercise that cannot be performed with control, cannot be loaded progressively, or causes pain
should be replaced rather than endured. The pattern matters; the specific exercise usually does not.

## Technique and Load Standards

Load is added when the current load is performed well, not when the calendar says so. Two practical
gates:

- **Repetition quality:** the last repetition of a working set should look like the first. When
  the final reps degrade — range shortening, position collapsing, bar path changing — the load is
  ahead of the athlete.
- **Repetitions in reserve:** most productive work sits 1–3 repetitions short of failure. Training
  to failure on compound lifts costs disproportionate recovery for a small additional stimulus, and
  is best reserved for isolation work where the risk is low.

## When Progress Stalls

Before concluding that a programme has stopped working, check in this order:

1. **Recovery:** sleep, food, and life stress explain more stalls than programming does.
2. **Adherence:** the sessions actually completed, not the sessions written.
3. **Volume:** below the minimum to progress, or above what is being recovered from.
4. **Variation:** the same exercise for many months with no change in stimulus.
5. **Expectation:** an intermediate expecting beginner rates of progress is not stalled.

Only after these does changing the programme itself make sense. Most stalls resolve with a deload,
a small volume adjustment, or a night's sleep — not with a new template.

## Intensity Guidelines

### For Strength Development
- Primary range: 80-95% 1RM (1-6 reps)
- Volume: 3-8 sets per exercise
- Frequency: 2-4x per week per lift
- Rest: 3-5 minutes between sets

### For Hypertrophy
- Primary range: 65-85% 1RM (6-12 reps)
- Volume: 3-6 sets per exercise
- Frequency: 2-3x per week per muscle group
- Rest: 1-3 minutes between sets

## Recovery Principles

### Between Sessions
- Minimum 48 hours between training same muscle group at high intensity
- More frequent training possible at lower volumes/intensities
- Monitor performance as primary indicator

### Deload Protocols
Recommended every 4-6 weeks:
- Reduce volume by 40-50%, or
- Reduce intensity by 20%, or
- Reduce both slightly (30% volume, 10% intensity)

### Signs You Need Recovery
- Performance plateau or regression for 2+ sessions
- Persistent muscle soreness
- Sleep disruption
- Motivation decrease
- Elevated resting heart rate

## Key Takeaways

1. Progressive overload is non-negotiable for continued adaptation
2. Volume must be within MEV-MRV range for optimal results
3. Intensity selection depends on primary goal (strength vs hypertrophy)
4. Recovery is when adaptation occurs—program it systematically
5. Individual variation is significant—monitor and adjust based on response
