Formula

Three everyday signals combine into one actionable readiness number.

Readiness = 100 - soreness*6 - max(0, 8-sleep)*8 - max(0, sessions-5)*5

Alternative Form

Train hard 80+, moderate 60+, easy 40+, rest below 40

C	Call	plan	Band prescription

Explanation

Soreness 4, seven hours sleep and four sessions costs 32 points — 68/100, a moderate day.

Derivation

Coaching heuristics formalized; validated against training-log practice, not labs.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Price the soreness.

Cost = soreness x 6

Soreness:4/10

Intermediate: 4 x 6

Result: -24 points

Step 2

Price the sleep debt.

Cost = max(0, 8 - sleep) x 8

Sleep:7 h

Intermediate: (8-7) x 8

Result: -8 points

Step 3

Price the weekly load.

Cost = max(0, sessions - 5) x 5

Sessions:4

Intermediate: no excess

Result: -0 points

Step 4

Subtract from 100.

Readiness = 100 - costs

Costs:32

Intermediate: 100 - 32

Result: 68/100 readiness

Step 5

Map to a call.

80+ hard, 60+ moderate, 40+ easy, else rest

Score:68

Intermediate: band lookup

Result: Train moderate

Step 6

Prescribe rest.

Soreness 4-6 means ~24 h

Soreness:4/10

Intermediate: rest lookup

Result: 24 h before repeating

Final Answer

68/100

Worked Examples

See how the calculator works with different scenarios.

Scenario

Soreness 4, 7 h sleep, 4 sessions.

Inputs

Soreness:4

Sleep:7 h

Calculation

100 - 24 - 8 - 0 = 68

Result

68/100 — moderate

Interpretation

Cap top sets at RPE 8; volume as planned.

Understanding Your Result

Your Result: Readiness: 68/100

Typical range: Readiness 80+ means full steam, 50-80 moderate, under 50 easy or off. Muscles need 24-72 hours by size.

What This Means

The output compresses soreness, sleep and recent training into a readiness score plus concrete rest guidance.

Why It Matters

Adaptation happens between sessions. Training hard while unrecovered adds fatigue without stimulus — the score makes that visible.

Professional Interpretation

Coaches watch weekly load ratios and morning signals, deloading at the first multi-day slide rather than after a crash.

Score vs soreness

Soreness alone misleads — you can be recovered yet sore, or fresh-feeling yet fatigued. The score blends three signals.

Trends beat days

One low score means an easy day; a week of sliding scores means a deload.

Recommendations

•Sleep 7-9 hours nightly
•Separate hard sessions by 48+ hours per muscle
•Deload every 4-8 weeks
•Eat 1.6-2.2 g/kg protein while recovering

Educational Content

Introduction

This calculator turns recovery signals into a train-or-rest decision with exact rest prescriptions.

Concept Explanation

Stress plus recovery equals adaptation. The score weighs what you did against how you bounced back.

Applications

▸Daily readiness checks

▸Rest-day planning

▸Deload timing

▸Frequency setup

▸Overtraining flags

▸Comeback pacing

Benefits

•0-100 readiness
•Hour-level rest guidance
•Deload loads
•Frequency advice
•Stall diagnosis

Limitations

•Subjective soreness input
•No HRV integration
•No illness detection
•Population averages
•Single-day snapshot

Best Practices

•Rate soreness pre-warmup
•Log sleep honestly
•Compare identical weeks
•Deload on schedule
•Pair with a training log

Common Misconceptions

Myth: Soreness equals growth.

Truth: Soreness signals novelty, not effectiveness. Repeat bouts stop hurting while still building.

Myth: More rest is always safer.

Truth: Excess rest detrains. The minimum effective rest beats maximum rest for progress.

Myth: Deloads waste a week.

Truth: Deloads resensitize muscles; PRs cluster in the two weeks after, not before.

Practical Tips

•Walk 20 minutes on rest days
•Keep bedtime within 30 minutes daily
•Protein 30-50 g per meal while recovering
•Hydrate — dehydration mimics fatigue
•Contrast hard days with truly easy ones
•Schedule deloads before you need them

Common Mistakes

Training through heavy soreness

Soreness 7+/10 means incomplete repair. Train another muscle or go light.

Skipping deloads

Eight hard weeks without relief stall everyone. Cut volume half every fourth to eighth week.

All-or-nothing rest

Full couch days recover worse than light activity for most soreness. Move gently.

Caffeine-masking fatigue

Stimulants hide readiness signals. If you need double caffeine to train, you need rest.

Same muscle daily

Daily hard chest days outrun 48-72 hour repair. Alternate or split volume.

Ignoring sleep debt

Five-hour nights for a week cost more strength than any program tweak gains.

Assumptions

This calculator makes the following assumptions to provide estimates:

Healthy adult: Guidance fits healthy adults; illness and injury need clinicians.

Honest soreness rating: Scores assume a calibrated 0-10 pre-warmup rating.

Normal nutrition: Protein and calories near targets; deficits slow every timeline.

No red flags: Fever, sharp pain and chest symptoms override any score — see a doctor.

Single-day snapshot: The score reads today; trends across days drive deload calls.

Limitations

Be aware of these limitations when using this calculator:

Subjective inputs: Soreness perception varies 2-3 points between lifters.

No physiology: Heart-rate variability and blood markers would sharpen the score.

Population bands: 24-72 hour windows are averages; individuals vary widely.

Stress blind: Life stress impairs recovery but sits outside the math.

Snapshot only: One score cannot see the accumulating week behind it.

Frequently Asked Questions

Answers to common questions about this calculator.

How long do muscles need to recover?

Small muscles recover in 24-48 hours, large ones in 48-72. Soreness, sleep and nutrition shift the window by a full day either way.

Should I train while sore?

Light soreness (1-3/10) is fine to train through with a warm-up. Heavy soreness (7+/10) means the muscle has not rebuilt — train something else.

How much sleep for recovery?

Seven to nine hours. Deep sleep releases growth hormone; one short night measurably slows next-day performance.

What is a deload week?

A planned easy week at 40-60% volume that sheds accumulated fatigue. Strength typically jumps the week after, not during.

How long should I rest between sets?

Strength 3-5 minutes, hypertrophy 60-120 seconds, endurance 30-60 seconds. Shorter rests save time; longer rests lift more weight.

What is the readiness score?

A 0-100 summary of soreness, sleep and recent load. Above 80 means train hard, 50-80 moderate, below 50 go easy or rest.

Does protein timing matter for recovery?

Total daily protein matters most, but 20-40 g within a few hours post-training slightly improves repair. Do not stress the 30-minute window myth.

Do I need rest days?

Yes — 1-2 weekly. Muscles rebuild between sessions, not during them; rest days are when training becomes fitness.

What is overtraining?

True overtraining is rare; under-recovery is common. Weeks of rising fatigue, falling lifts and poor sleep mean cut volume 50% for a week.

Does cardio hurt recovery?

Light cardio improves recovery via blood flow. Hard intervals compete with lifting — cap them at 1-2 weekly during strength blocks.

How does age change recovery?

Recovery slows roughly 10-15% per decade past 30. Older lifters thrive on the same volume with more frequency and longer deloads.

When should I take a deload?

Every 4-8 weeks, or when lifts stall two weeks with rising fatigue. Scheduled deloads beat forced ones from injury.
