Workout Log Structure

How the physical data is structured. Sets, reps, load, and RPE.

Why Track Your Training?

Progressive overload—the gradual increase in training stimulus—is the fundamental driver of adaptation. Without tracking, you’re guessing. With tracking, you have data. Data enables progress.

A workout log transforms subjective feelings into objective metrics. “I think I’m getting stronger” becomes “I added 10 pounds to my squat in 4 weeks.” The difference between hoping and knowing.

The Four Essential Data Points

Every workout log should capture four critical variables:

1. Sets

The number of times you perform a group of repetitions for a given exercise. Sets determine your total training volume and how you distribute fatigue.

Example: 4 sets of squats means you’ll perform the squat exercise four separate times with rest periods between.

Typical Ranges:

  • Strength focus: 3-5 sets
  • Hypertrophy focus: 3-6 sets
  • Endurance focus: 2-4 sets

2. Reps (Repetitions)

The number of times you perform a movement within a single set. Rep ranges dictate the primary adaptation your body makes.

Example: 5 reps means you perform the movement five times before resting.

Rep Range Effects:

  • 1-5 reps: Maximal strength, neural adaptations
  • 6-12 reps: Hypertrophy (muscle growth), balance of strength and size
  • 12-20+ reps: Muscular endurance, metabolic stress

3. Load

The amount of weight lifted, typically expressed in pounds (lbs) or kilograms (kg). For bodyweight exercises, this may be noted as “BW” or with added weight (e.g., “BW +25lbs”).

Example: 225 lbs on the barbell for squats

Load Progression Methods:

  • Absolute increase: Add 5-10 lbs when you hit target reps
  • Percentage-based: Work at 80% of your 1-rep max (1RM)
  • Relative: Use RPE to determine appropriate load

4. RPE (Rate of Perceived Exertion)

A subjective scale from 1-10 indicating how difficult a set was, with specific focus on “reps in reserve” (RIR)—how many more reps you could have completed.

RPE Scale:

  • RPE 5-6: Could do 4-5 more reps (warm-up sets)
  • RPE 7: Could do 3 more reps (moderate difficulty)
  • RPE 8: Could do 2 more reps (challenging)
  • RPE 9: Could do 1 more rep (very hard)
  • RPE 10: Absolute failure, zero reps left (maximum effort)

Why RPE Matters: Some days you’re stronger than others due to sleep, nutrition, stress, or recovery. RPE allows you to autoregulate—adjusting load based on how you feel while maintaining appropriate stimulus.

Training Splits: How to Organize Your Week

A training split determines which muscle groups or movement patterns you train on specific days. The right split depends on your goals, recovery capacity, and schedule.

Full Body Split (3 Days/Week)

Train all major muscle groups each session.

Structure:

  • Monday: Full Body A
  • Wednesday: Full Body B
  • Friday: Full Body C

Example Full Body A:

  • Squat: 4x5, RPE 8
  • Bench Press: 4x6, RPE 8
  • Bent-Over Row: 3x8, RPE 8
  • Overhead Press: 3x8, RPE 7
  • Romanian Deadlift: 3x10, RPE 7

Best For: Beginners, busy schedules, strength focus, maximum frequency for skill development

Pros: Train each muscle group 3x per week, efficient, flexible scheduling
Cons: Long sessions, potentially fatiguing for advanced lifters

Upper/Lower Split (4 Days/Week)

Separate upper and lower body training across four days.

Structure:

  • Monday: Lower Body
  • Tuesday: Upper Body
  • Thursday: Lower Body
  • Friday: Upper Body

Example Lower Day:

  • Squat: 5x5, 80% 1RM
  • Romanian Deadlift: 4x8, RPE 8
  • Leg Press: 3x12, RPE 8
  • Leg Curl: 3x12, RPE 8
  • Calf Raise: 4x15, RPE 8

Example Upper Day:

  • Bench Press: 5x5, 80% 1RM
  • Pull-ups: 4x8, RPE 8
  • Overhead Press: 3x8, RPE 8
  • Barbell Row: 3x10, RPE 8
  • Bicep Curl: 3x12, RPE 8

Best For: Intermediate lifters, balanced development, those who can train 4 days weekly

Pros: Good volume distribution, adequate recovery, hits each muscle 2x per week
Cons: Requires 4-day commitment, less flexible than 3-day split

Push/Pull/Legs (6 Days/Week)

Divide training by movement pattern: pushing movements, pulling movements, and legs.

Structure:

  • Monday: Push (Chest, Shoulders, Triceps)
  • Tuesday: Pull (Back, Biceps)
  • Wednesday: Legs
  • Thursday: Push
  • Friday: Pull
  • Saturday: Legs
  • Sunday: Rest

Example Push Day:

  • Bench Press: 5x5, 85% 1RM
  • Overhead Press: 4x6, RPE 8
  • Incline DB Press: 3x10, RPE 8
  • Lateral Raise: 3x15, RPE 7
  • Tricep Pushdown: 3x12, RPE 8

Best For: Advanced lifters, bodybuilding focus, high recovery capacity

Pros: High frequency (2x per week per muscle), specialization, shorter sessions
Cons: Requires 6-day commitment, demanding on recovery, not for beginners

Bro Split (5-6 Days/Week)

Train one major muscle group per day with high volume.

Structure:

  • Monday: Chest
  • Tuesday: Back
  • Wednesday: Shoulders
  • Thursday: Arms
  • Friday: Legs
  • Saturday: Optional (weak points/abs)

Example Chest Day:

  • Flat Bench Press: 4x8, RPE 8
  • Incline Barbell Press: 4x8, RPE 8
  • Decline DB Press: 3x10, RPE 8
  • Cable Fly: 3x12, RPE 8
  • Dips: 3x12, RPE 9

Best For: Advanced bodybuilders, those who love training, prioritizing size over strength

Pros: High volume per muscle group, complete focus, great pumps
Cons: Low frequency (1x per week), long sessions, inefficient for strength, requires 5+ days

Push/Pull (4 Days/Week)

Simplified version of PPL, combining leg work into push and pull days.

Structure:

  • Monday: Push + Quads
  • Tuesday: Pull + Hamstrings
  • Thursday: Push + Quads
  • Friday: Pull + Hamstrings

Best For: Intermediate lifters wanting more frequency than upper/lower but less than PPL

Pros: Balanced, efficient, good frequency
Cons: Less leg specialization than dedicated leg days

Powerlifting Split (4 Days/Week)

Organized around the three powerlifting movements: squat, bench, deadlift.

Structure:

  • Monday: Squat Focus + Accessories
  • Tuesday: Bench Press Focus + Accessories
  • Thursday: Deadlift Focus + Accessories
  • Friday: Overhead Press + Weak Point Work

Best For: Powerlifters, strength athletes, those focused on big three lifts

Pros: Optimized for strength gains on specific lifts, adequate recovery
Cons: Less overall muscle development, specific to powerlifting goals

Choosing Your Split

Consider these factors:

Training Frequency: How many days can you realistically commit?

  • 2-3 days: Full Body
  • 4 days: Upper/Lower or Push/Pull
  • 5-6 days: PPL or Bro Split

Experience Level:

  • Beginner: Full Body (3x/week)
  • Intermediate: Upper/Lower or Push/Pull
  • Advanced: PPL, Bro Split, or Specialized

Primary Goal:

  • Strength: Full Body or Powerlifting Split
  • Hypertrophy: PPL or Bro Split
  • General Fitness: Upper/Lower
  • Athletic Performance: Full Body or Upper/Lower

Recovery Capacity:

  • Lower capacity: Full Body (3x/week) or Upper/Lower
  • Higher capacity: PPL or 6-day splits

Progression Strategies

Linear Progression

Add weight each session or week. Best for beginners.

Example:

  • Week 1: Squat 3x5 @ 135 lbs
  • Week 2: Squat 3x5 @ 140 lbs
  • Week 3: Squat 3x5 @ 145 lbs

Double Progression

Increase reps within a range, then increase weight and drop back to lower reps.

Example:

  • Week 1: Bench 3x6 @ 185 lbs
  • Week 2: Bench 3x8 @ 185 lbs
  • Week 3: Bench 3x10 @ 185 lbs
  • Week 4: Bench 3x6 @ 195 lbs (increased weight, reset reps)

Wave Loading

Vary intensity across weeks to manage fatigue.

Example (4-week wave):

  • Week 1: 4x8 @ 70% 1RM, RPE 7
  • Week 2: 4x6 @ 75% 1RM, RPE 8
  • Week 3: 4x4 @ 80% 1RM, RPE 9
  • Week 4: Deload - 3x8 @ 60% 1RM, RPE 6

Digital vs. Analog Tracking

Paper Notebook:

  • Pros: No battery, quick, tactile, no distractions
  • Cons: No automatic calculations, harder to analyze trends
  • Best for: Minimalists, those who prefer writing

Spreadsheet (Excel/Google Sheets):

  • Pros: Customizable, formulas for auto-calculations, easy to review history
  • Cons: Requires computer/phone, setup time
  • Best for: Data enthusiasts, those comfortable with spreadsheets

Apps (Strong, Hevy, FitNotes):

  • Pros: Pre-loaded exercises, rest timers, progress charts, easy to use
  • Cons: Learning curve, potential subscription costs
  • Best for: Most people, especially beginners

Simple Template:

Date: ___________
Exercise        | Sets x Reps | Load    | RPE | Notes
---------------|-------------|---------|-----|-------
Squat          | 5x5         | 225 lbs | 8   | Good depth
Bench Press    | 4x6         | 185 lbs | 8   | Paused reps
Barbell Row    | 4x8         | 155 lbs | 7   | Felt easy

What to Track Beyond the Basics

Optional but valuable:

  • Bodyweight: Weekly or daily weigh-ins
  • Sleep: Hours per night
  • Stress Level: 1-10 scale
  • Energy Level: How you felt before training
  • Injuries/Pain: Any discomfort or limitations
  • PR (Personal Records): Date and details of new bests
  • Photos: Monthly progress pictures

The Most Important Rule

Track consistently. An imperfect system used every workout beats a perfect system used occasionally. Whether you use a torn notebook, a sophisticated app, or a spreadsheet doesn’t matter.

What matters: you record what you did, analyze what worked, and plan what comes next.
