NOVASTRA

Calculators

Six numbers that get done badly by hand, done properly and without leaving your browser.

1RM calculator and percentage loads

What you would lift once, worked out from the reps you actually do. Plus the percentage table to build the session.

1RM

What plates to put on the bar

The weight you want, split per side, with the plates your gym actually has.

KG

Calorie and macro calculator

What you burn in a day and how to split it, with the equation that gets it least wrong outside a lab.

KCAL

How much protein you need per day

Grams per day and per meal, using the range the meta-analyses give and not the one on the tub.

PROT

FFMI calculator

How much muscle you carry for your height, in a number that can be compared between different people.

FFMI

Weekly sets per muscle

The weekly dose split across the days you train, using the range the evidence gives and not anyone's gym folklore.

SETS

This is worked out here, in your browser. Nothing you type — weight, height, anything — leaves your phone: this page sends no data anywhere.
