Frequently asked questions

Why does low intensity give zero rest days?

Low-intensity training places less stress on the body, so recovery can happen within the same day.

Can I have more rest days than workout days?

This formula caps rest days at about 30% of workout days, so it stays within a balanced range.

Is this a medical recommendation?

No, it's a general guideline. Listen to your body and adjust as needed.

Formulas

The math behind this calculator, written out so you can verify the result.

Rest days formula

Rest days = round(workouts × intensity factor)

Intensity factor is 0.1 for low, 0.2 for moderate, 0.3 for high.

Example:

Input: 6 high-intensity workouts

Calculation: 6 × 0.3 = 1.8

Result: ≈ 2 rest days

Real-world use cases

Where this calculation shows up in everyday life.

Plan your weekly schedule

Balance training and recovery to avoid overtraining.

Example: 5 moderate workouts → 1 rest day

Adjust for intensity

Higher intensity requires more recovery time.

Example: 6 high workouts → 2 rest days
