## What is FitBoost?

FitBoost is a training log for strength and cardio that turns your history into a concrete answer: how much to lift next.

■ Free has no caps
Unlimited routines, unlimited custom exercises, unlimited records. No account needed, and your log stays on your device. There is no wall on the free plan.

■ It works out your next load
Completed sets of 12 reps or fewer feed Epley, Brzycki and Lombardi estimates, and we take the median. Log RIR and the reps you had left sharpen it further.

■ 535 exercises, every one with a guide
Every exercise carries setup, execution, breathing and precautions. Filter by muscle group and equipment to find what you need.

■ Stats you can see on a body
A body map shows which muscles you worked and how fatigued they are, alongside weekly volume and muscle balance.

■ Five languages
Korean, English, Japanese, Simplified Chinese and Traditional Chinese.

FitBoost PRO adds a personal 1-15 rep load curve, a progressive overload coach, plateau detection, plate math and a weekly coaching report.
