Frequently Asked Questions

What calculators does FitNova360 offer?

FitNova360 offers calculators for one-rep max, warm-up sets, barbell loading, deloads, relative strength, muscle gain macros, fruit smoothie nutrition, and daily sugar allowance, covering both training and nutrition.

How is one-rep max calculated?

One-rep max is calculated using the Epley formula, weight × (1 + reps ÷ 30), based on a set you have already performed.

How many warm-up sets should I do before lifting heavy?

Most lifters need 3 to 5 warm-up sets that build from roughly 40 to 90 percent of their working weight.

When should I take a deload week?

A deload week is usually taken every 4 to 8 weeks, or whenever your lifts stall or fatigue builds up.

What is relative strength?

Relative strength is the ratio of the weight you lift to your own body weight, showing your strength level in context.

How much added sugar should I eat per day?

Most adults should keep added sugar under roughly 25 to 36 grams, or 6 to 9 teaspoons, per day.

How accurate are these calculators?

These calculators give evidence-based estimates rather than exact medical figures, so individual results can vary.
