About Mesocycle Plan Calculator

A mesocycle ramps intensity across loading weeks then finishes with a deload. Going 70% to 90% over a four-week block means three loading weeks with roughly 6.7 percentage points added each, then a final week near 58%. The step size shrinks as blocks lengthen, which is why longer mesocycles feel more gradual.

Formulas

Weekly step

step = (peak intensity - start intensity) / (weeks - 1)

Deload week

about 65% of peak intensity

Worked example

With the default values below, Mesocycle Plan Calculator returns Weekly Intensity Step of 6.67%. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

How long should a mesocycle be?

Three to six weeks for most lifters. Shorter blocks suit advanced athletes who accumulate fatigue quickly.

Should volume rise with intensity?

Usually not - as intensity climbs, volume should fall to keep total stress manageable. Rising both at once is a fast route to overreaching.
