Conjugate Method Strength Training App
Frequently Asked Questions & Guide

Mainstream workout trackers are built on the assumption of progressive linear overload using static straight barbell lifts. They give you a single bucket for "Barbell Squat" or "Barbell Bench Press".

When a conjugate powerlifter performs a Safety Squat Bar to a 13-inch Box with 100 lbs of Band Tension, a generic app breaks down:

• Data Corruption: If you log it under "Squat", your 1RM, volume charts, and PR history get completely polluted, rendering long-term trend analysis useless.
• Cluttered Exercise Lists: If you create a custom exercise for every combination, your library explodes into hundreds of cluttered items like "SSB Box Squat 13in Light Bands" with no structured linking, no automatic PR inheritance, and no equipment awareness.
• Spreadsheet Friction: Spreadsheets cannot calculate dynamic top and bottom band tension curves on the fly, quickly break when modifying formulas, and are virtually impossible to operate at the rack with chalk on your hands between heavy singles.

Equipment Identity Hashing is Iron Forge's foundational data architecture. Rather than relying on simple text names, Iron Forge generates a cryptographic deterministic fingerprint for every movement based on its physical properties:

Hash = SHA-256(Base Lift + Bar Spec + Attachment/Depth + Resistance Curve + Stance)

• Base Movement: Squat, Bench Press, Deadlift, Overhead Press.
• Specialty Bar: Safety Squat Bar (65 lbs), Giant Cambered Bar, Duffalo/Buffalo Bar, Swiss Bar, Football Bar, Trap Bar, or Competition Power Bar.
• Modification / Depth: Box height (e.g. 11", 13", 15"), Board Press (1-Board through 5-Board), Pin setting (Pin 1 through 5), or Deficit height (1", 2", 3").
• Accommodating Resistance: Band tension profile (Micro, Mini, Monster Mini, Light, Average, Strong) or Chain link weight.

This ensures your Safety Squat Bar Box Squat with Light Bands has its own dedicated 1RM, 3RM, 5RM, volume load, and historical progression that is mathematically isolated from your straight bar competition squat.

In the conjugate method, Louie Simmons established that rotating variations every 1–3 weeks prevents neurological accommodation and allows athletes to train at 90%+ intensities year-round without burning out.

Iron Forge turns this philosophy into an automated tracking engine:

• Instant Milestone Detection: Whenever you enter a set, Iron Forge compares your weight and reps against your all-time records for that exact variation hash.
• Multi-Rep Bracket Tracking: Dedicated PR tracking for 1RM, 2RM, 3RM, 5RM, and 8RM across every specialty bar and attachment combination.
• Rack Display: When you select a variation during your workout, your all-time PR and previous attempt history are prominently displayed on screen before you unrack the bar.

Accommodating resistance changes the resistance profile of the lift. Unlike straight weight, resistance bands exert variable tension: minimal tension at the bottom of the movement (the chest or the hole) and maximum peak tension at lockout.

Iron Forge integrates a mathematical Band Tension Calculator calibrated against standard 41-inch powerlifting bands:

• Band Types Supported: Micro Bands, Mini Bands, Monster Mini Bands, Light Bands, Average Bands, and Strong Bands (choked or looped).
• Dual-Point Tension Math: The app computes estimated Tension at the Chest / Hole (Bottom Tension) and Tension at Full Lockout (Top Tension) based on standard rack setups.
• Dual Load Display: Log either straight bar weight (e.g. 315 lbs) with attached band metadata or toggle Total Combined Peak Load (e.g. 315 lbs bar + 120 lbs band tension = 435 lbs at lockout).

Dynamic Effort training uses 3-week pendulum waves to maximize explosive barbell speed and rate of force development (RFD). A typical wave progresses:

• Week 1: 50% bar weight + 25% band tension (75% total) — 10-12 sets of 2 reps
• Week 2: 55% bar weight + 25% band tension (80% total) — 10-12 sets of 2 reps
• Week 3: 60% bar weight + 25% band tension (85% total) — 8-10 sets of 2 reps
• Week 4: Rotate bar or band setup and restart the wave at Week 1 percentages.

Iron Forge automates this entire cycle. Input your base 1RM, select your wave percentage template, and the app automatically calculates the exact barbell weight for each week, tracks your 60-second rest intervals, and alerts you when it's time to rotate movements.

Iron Forge was engineered for chalk-covered hands inside loud powerlifting gyms. You never have to hunt through complex menus or type small text while out of breath:

• Single-Tap Logging: Large, high-contrast buttons allow you to adjust weights in 2.5, 5, 10, or 25 lb / kg increments with a single tap.
• Smart Plate Calculator: Tap the plate icon to instantly see the exact plate breakdown per side for 45, 35, 25, 10, 5, and 2.5 lb plates (or competition calibrated kilogram plates).
• Automatic Rest Timers: Logging a set immediately launches your customizable rest timer with audible countdown alerts.
• 100% Offline Chalk Mode: Iron Forge stores all workout data in local SQLite cache. Even with zero Wi-Fi or cellular signal in a basement gym, logging is instantaneous and syncs automatically when connection returns.

Building a variation takes less than 5 seconds in the Variation Lab:

1. Select Base Lift: Choose Squat, Bench Press, Deadlift, or Overhead Press.
2. Select Bar Type: Pick from our library of 40+ pre-calibrated bars (e.g. Safety Squat Bar 65 lbs, Giant Cambered Bar 65 lbs, Duffalo 55 lbs, Swiss Bar 35 lbs, Buffalo Bar, Trap Bar, etc.).
3. Choose Attachment / Height: Select Box Squat (choose height from 10" to 18"), Board Press (1 to 5 boards), Pin Press / Rack Pull (Pin 1 through 5), or Deficit (1" to 3").
4. Attach Accommodating Resistance: Choose your bands (Micro, Mini, Light, Average, Strong) or Chain setups.

The system instantly creates your variation hash and pulls up your historical PR history for that setup.

The classic conjugate method utilizes a four-day training split divided into Max Effort (strain for maximum neural recruitment) and Dynamic Effort (bar speed for explosive power):

• Day 1 — Max Effort Upper: Work up to a 1RM, 2RM, or 3RM on a primary variation (e.g. Close-Grip Incline, 2-Board Bench, or Football Bar Bench). Rotate movement every 1–2 weeks. Follow with 3–4 heavy accessories targeting triceps, lats, and upper back.
• Day 2 — Max Effort Lower: Work up to a 1RM–3RM on a primary variation (e.g. SSB Box Squat, Deficit Deadlift, or Good Mornings). Rotate weekly. Follow with heavy glute-ham raises, reverse hypers, and abs.
• Day 3 — Dynamic Effort Upper: 8–9 sets of 3 reps at 40–50% straight weight + 25% band tension with 3 different grips (close, medium, wide). Move the bar as fast as humanly possible on 45–60 second rest.
• Day 4 — Dynamic Effort Lower: 8–12 sets of 2 reps on Box Squats on a 3-week wave, followed immediately by 6–10 speed deadlift singles at 50–60% + band tension.

From the bottom navigation bar, tap Records to open your personal strength archives:

• Variation PR Matrix: Filter all recorded PRs by primary lift, specialty bar, or date range.
• Interactive Progression Charts: Tap any variation to view a historical scatter plot of your 1RM, 3RM, and 5RM attempts over time.
• Carryover Correlation: Review which specialty bar PRs correlated with your largest competition 1RM increases.
• Estimated 1RM (e1RM): Iron Forge computes e1RM using powerlifting-specific formulas adapted for accommodating resistance.
