Training Cycle Planner (Weeks/Deload)
Map work and deload weeks across a training cycle and see which weeks the deloads land on.
What this tool does
This calculator structures a training cycle by dividing its total length into work weeks and deload weeks at a fixed interval. Enter the cycle length and how often a deload falls, and it returns the work and deload totals, the shape of each repeating block, the specific week numbers the deloads land on, and any work weeks left over after the final deload. It models block periodisation with regular planned recovery; it does not prescribe what happens inside either kind of week.

How the Training Cycle Planner works
Give it a cycle length in weeks and an interval for deloads. The tool counts how many deload weeks fit, subtracts them to get work weeks, and shows the repeating block those two numbers come from along with the exact weeks the deloads fall on. Seeing the week numbers matters more than the totals: a cycle can contain the right count of recovery weeks and still put one in an inconvenient place.
The formula
Deload weeks = floor(cycle length ÷ deload interval), and work weeks = cycle length − deload weeks. An interval of every 4 weeks means the fourth week is the deload, so each block is 3 work weeks plus 1 deload. For the default 8-week cycle: floor(8 ÷ 4) = 2 deload weeks, falling on weeks 4 and 8, leaving 8 − 2 = 6 work weeks arranged as two blocks of three.
When the cycle length is not a whole number of blocks, the remainder becomes work weeks after the final deload. A 10-week cycle with deloads every 4 weeks still has 2 deloads, on weeks 4 and 8, and 8 work weeks: three, then three, then two to finish. The tool reports that tail rather than leaving you to notice the cycle ends mid-block.
Where this method is most accurate
The model assumes evenly spaced deloads and whole-week units, which suits linear and block periodisation with a consistent interval. It does not represent auto-regulated deloads triggered by fatigue or performance markers, competition peaking, or undulating schemes where volume and intensity vary within a single week rather than across blocks (Zourdos et al., 2016). The structural logic it follows, alternating accumulation with planned recovery, is the one set out in the standard periodisation texts (Bompa and Haff; Stone, Stone and Sands, 2007).
What this tool does not do
It organises training time and nothing else. It does not prescribe exercises, set and rep schemes, or intensities for either kind of week. It does not assess recovery capacity, training age, or readiness to progress, and it cannot judge whether a given interval suits you. Injury history, medical conditions, and total training volume are all outside what a week-counting calculator can see.

This tool is for educational and informational purposes only. It is not medical advice, coaching, or a training prescription. Consult a qualified strength coach or sports medicine professional before beginning or modifying any training program. Individual recovery needs, training experience, and health status vary widely and cannot be captured by a cycle-planning calculator alone.
Questions
- What does a deload every 4 weeks actually look like?
- Three work weeks then one deload, repeating. The interval names which week is the deload, so 4 means the fourth week of each block. The tool spells the block out and lists the week numbers, so an 8-week cycle shows deloads on weeks 4 and 8.
- What happens if my cycle does not divide evenly?
- The leftover weeks become work weeks after the final deload. A 10-week cycle with deloads every 4 weeks has deloads on weeks 4 and 8, then finishes with two work weeks rather than a third full block. The result says so explicitly, because a cycle ending mid-block is easy to miss when you only see totals.
- What is a deload week?
- A planned week of reduced training volume, intensity, or both, meant to shed accumulated fatigue while keeping movement patterns and fitness. Common approaches cut working sets substantially, drop intensity, or reduce frequency. This calculator counts the weeks; what goes in them is a programming decision it does not make.
- How often do deloads typically fall?
- Periodisation models commonly place them every 3 to 5 weeks, but the right interval depends on training age, volume, and how heavy the work is in absolute terms. Beginners moving lighter loads often go longer between them; high-volume or high-intensity blocks tend to need them sooner. The tool takes whatever interval you give it.
- Why does the calculator refuse a deload every week?
- Because an interval of one makes every week a deload and leaves zero work weeks, which is not a training cycle. An interval of zero used to divide by zero outright and print an infinite number of deloads. Both are now rejected with a message rather than an impossible plan.
- Can I adjust the deload timing mid-cycle?
- The calculator assumes a fixed interval, which is what makes it a plan. Auto-regulated training moves deloads based on performance drops, subjective fatigue, or readiness scores instead. Treat the structure here as the template you start from and adjust against, not a schedule you owe adherence to.
- Does this account for peaking or a taper?
- No. It sorts weeks into work and deload only. Competition peaking and tapering follow different logic, with progressive volume reductions alongside maintained or rising intensity in the final weeks, which a two-category split cannot express.
Sources & Methodology
Deload weeks = floor(cycle length ÷ deload interval); work weeks = cycle length − deload weeks. An interval of d means the dth week is the deload, so each repeating block is d − 1 work weeks plus one deload, and deloads fall on weeks d, 2d, 3d and so on. Any weeks past the final deload are reported as trailing work weeks. This models block periodisation with a fixed interval, the structure set out in the standard periodisation texts. Intervals of one week, or of zero, are rejected rather than returning a cycle with no work in it.
