Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Body Recomposition Calculator
Estimate the daily calorie target needed to simultaneously lose fat and gain muscle based on lean body mass, training frequency, experience, and your recomposition focus. Best used by natural lifters aiming to change body composition without a strict bulk or cut.
Hypertrophy Volume Calculator
Calculate the optimal number of weekly sets for a target muscle group based on your training experience, recovery capacity, and session frequency. Use it to avoid both under-training and junk volume that stalls progress.
Optimal Weekly Volume
8 sets
Under 10 weekly sets sits near the minimum effective volume; most lifters need at least 10 hard sets per muscle group per week to see measurable growth.
Weekly set ranges follow Renaissance Periodization's MEV-MAV-MRV framework, where roughly 10-20 hard sets per muscle group per week drives most hypertrophy.
