Understanding training volume planner — sensitivity table
Everyday editorial team · GEOINNOVATION CO., LTD · Published · Updated
What this calculation is for
A training-volume plan makes a weekly progression visible rather than treating a percentage increase as a one-time change. It also distinguishes total volume from time scheduled for sessions.
How the method works
The chosen weekly volume changes geometrically by the progression rate and is summed across weeks. Session count and minutes per session provide a separate total-time estimate. The displayed model uses: Apply the entered weekly progression rate and sum planned time and volume across the schedule.
A worked example
For an illustrative training volume planner scenario, use Sessions per week: 4 sessions; Minutes per session: 45 minutes; Weekly distance or volume: 15 units/week; Weekly increase: 5 %; Plan length: 8 weeks; Rest days per week: 2 days. The modeled planned total training volume is 143.2 units. These are example assumptions, not current prices, official benefit amounts or personalized advice.
Assumptions and real-world differences
Volume units must remain consistent. Rest-day context does not evaluate recovery, overlapping workouts or injury risk. A compounded increase can quickly create an impractical plan. Not an individualized training program; recovery, injury history and health are not assessed.
Reading the weekly distance or volume sensitivity table
The tool evaluates the same model across a range of weekly distance or volume values while holding other assumptions constant. Choose a realistic low value, high value and number of points. Each row reports the same headline measure; the table is a set of conditional calculations, not a probability distribution or a forecast. Input-step rounding can make nearby rows equal.

Sensitivity analysis: 5 comparison points
Weekly distance or volume ranges from 7.5 units/week to 22.5 units/week.
- Weekly distance or volume: 7.5 units/week: 71.6 units
- Weekly distance or volume: 11.5 units/week: 109.8 units
- Weekly distance or volume: 15 units/week: 143.2 units
Frequently asked questions
- Does increasing volume by 5% mean adding the same amount each week?
- No. A percentage progression compounds, so the absolute addition grows as the previous week’s volume grows.
- Which inputs should I check before using this training volume planner estimate?
- Check sessions per week, minutes per session, weekly distance or volume, weekly increase, plan length, rest days per week. Match each field’s unit and time period, then compare the detailed rows rather than treating the headline alone as the complete answer.
- Does the most favorable row show the most likely outcome?
- No. The table assigns no likelihood to any row. It shows how the result responds to the chosen assumption, and you remain responsible for selecting a plausible range.
