# CrossFit

CrossFit defines fitness as work capacity across broad time and modal domains. Training combines barbell strength, Olympic lifting, gymnastics, and metabolic conditioning (monostructural cardio) into varied, high-intensity workouts. The goal is not to be the best at any single physical quality but to be highly capable across all of them.

## Defining Principles

- **Variance**: Workouts are intentionally varied so that no single adaptation is overemphasized and no movement becomes a crutch. The athlete who trains everything is fitter than the specialist.
- **Constant high intensity**: The defining feature of most CrossFit workouts (WODs) is that they are performed at or near maximum sustainable intensity. Time and reps are scored, creating competitive accountability for effort.
- **Functional movement patterns**: CrossFit selects movements that are universal motor recruitment patterns — squat, hinge, press, pull, carry, and their loaded gymnastics equivalents. Machines and isolation exercises are largely absent.
- **Ten physical domains**: Training aims to develop cardiovascular endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy simultaneously.
- **Metabolic conditioning as a first-class citizen**: Unlike pure strength sports, conditioning (running, rowing, cycling, jump rope) is not an afterthought — it is integrated into every training session alongside strength and skill work.

## What Distinguishes CrossFit from Other Systems

CrossFit is the only major training system that explicitly programs for work capacity across all time domains (seconds to 30+ minutes) within a single training session and training week. Unlike powerlifting or weightlifting, there is no fixed competition lift set; unlike bodybuilding, appearance is not the goal; unlike calisthenics, external load is central to the methodology. The combination of Olympic lifting, gymnastics, and metabolic conditioning into a single session is unique to CrossFit and its derivatives.

## Athlete Profile

CrossFit suits athletes who:
- Want broad fitness across strength, conditioning, and skill simultaneously
- Are motivated by competitive scoring (times, rounds, reps) and community
- Enjoy high intensity and varied daily workouts rather than repetitive programs
- Have athletic backgrounds or are comfortable learning barbell and gymnastics movements

**Not ideal for:** athletes pursuing a single performance metric (1RM total, physique competition, Olympic total) or those with injuries incompatible with high-intensity mixed modal training.

## Core Movement Categories

CrossFit programs across three broad domains:

| Domain | Representative movements |
|---|---|
| Barbell strength | Back squat, deadlift, overhead press, bench press |
| Olympic lifting | Snatch, clean & jerk, power clean, hang clean |
| Gymnastics | Pull-ups, dips, push-ups, handstand push-ups, muscle-ups, toes-to-bar |
| Monostructural | Running, rowing, cycling, jump rope, ski erg |

## WOD Formats

| Format | Definition | Example |
|---|---|---|
| AMRAP | As many rounds/reps as possible in fixed time | Cindy: 20-min AMRAP of 5 pull-ups, 10 push-ups, 15 squats |
| For Time | Complete prescribed work as fast as possible | Fran: 21-15-9 thrusters + pull-ups |
| EMOM | Every minute on the minute | 10-min EMOM: 2 power cleans |
| Chipper | Long list of movements done once each | 50 pull-ups, 50 push-ups, 50 sit-ups, 50 squats |
| Ladder | Ascending or descending rep scheme | 1-2-3-4-5 clean and jerks |

## Typical Training Parameters

| Variable | Strength component | WOD (metabolic) |
|---|---|---|
| Intensity | 70-85% 1RM | Near-maximal sustainable effort |
| Duration | 15-30 min | 5-30 min |
| Rest between sets | 2-3 min | Minimal / none |
| Frequency | 3-5x/week | 4-5 WODs/week |

CrossFit training does not prescribe fixed volume landmarks per muscle group. Fatigue accumulates across modalities; recovery management requires monitoring sleep, HRV, and soreness patterns.

## Progression Pathway

**Foundations / On-ramp (0-6 months):** Learn movement standards for all three domains. Scale every WOD. `crossfit_foundations` is the structured on-ramp. Do not attempt Rx weights until technique is stable.

**Intermediate (6 months - 2 years):** Begin hitting Rx on most WODs. Add strength-focused accessory work (e.g., 5x5 squat before WOD). Work on gymnastic skill progressions (kipping pull-up, muscle-up).

**Advanced / Competitor (2+ years):** Two-a-days, deliberate weakness targeting, competition-specific peaking. CrossFit Games Open preparation requires tracking benchmark times year-over-year.

## Scaling Principle

Every WOD has three versions: **Rx** (prescribed), **Scaled**, **Beginner**. The correct scale preserves the intended metabolic stimulus — if Fran is supposed to take 3-8 minutes, choose a weight that keeps you in that window.

## Programs

| Program | Level | Key feature |
|---|---|---|
| `crossfit_foundations` | Beginner | 8-week GPP on-ramp, benchmark WODs, 3-domain introduction |
| `crossfit_intermediate` | Intermediate | WOD + strength supplemental, benchmark tracking |
| `crossfit_competition_prep` | Advanced | Two-a-days, weakness targeting, Open peaking |
