Why Kalv, and not a standard nutrition tracker?

A standard tracker was written for someone losing ten pounds by summer: one number, set once, and the same number whether you sat at a desk or sparred four times that week.

Someone who spars, rolls or wrestles every week is not that person. How much you should eat depends on your weight, how many sessions you put in and where you’re taking the weight — down to a limit, up a class, or holding it — and it changes when any of those change.

Kalv is built on exactly those three, and re-sets the day every morning from your scale. When the phase moves, the plan moves with it, and the detail underneath stays — so the next block starts from what actually happened in the last one.

Which sports does Kalv cover?

Six — MMA, boxing, muay thai, kickboxing, wrestling and BJJ. Anything else, you set your own limit by hand and the rest of the app works the same.

I fight amateur. Do I really need Kalv?

Most people who train have a scale and whatever they remember from last time. That works until the weight has to move and the sessions can’t get lighter.

Everything you’re working on runs through what you eat — the weight, the energy in the third round, what you recover between two sessions. Kalv covers that side of it. All year, every year, not just the weeks before a fight.
