Your CPET shouldn't end
when the test does.

A maximal CPET is a single morning, but the physiology it reveals should shape every workout, every long run, and every race-day fueling decision for the next six months. Aevox builds the bridge from the lab to your training — from a clinically-defensible interpretation, to longitudinal tracking, to a fueling protocol built from your own numbers.

A report that earns
a place in your training.

When your test is scored on Aevox, you walk out with more than a VO₂max number. You get substrate oxidation across the spectrum, fatmax and crossover heart rates, training zones anchored to your own VT1 and VT2 — and an interpretation your coach can actually use to write a block.

  • Heart rate zones from your physiology — not 220-minus-age.
  • Your fat-burning ceiling, in g/min, at a specific HR.
  • Thresholds with confidence scoring, not a single guess.
  • A fueling target that scales with intensity, not a generic range.

The test is the start —
Aevox tracks the trajectory.

Your Aevox report doesn't stop at the test — it becomes the foundation of a coach-first longitudinal dashboard that pairs your CPET interpretation with every workout file from Strava, Whoop, and Garmin. Three pillars, tracked month over month, every number grounded in your own data.

Your physiology,
in a bottle.

Fyool turns your Aevox test into an endurance fuel you actually mix and drink. Your carbohydrate burn rate, your substrate ratio, and your electrolyte losses determine a personal maltodextrin-to-fructose ratio, concentration, and sodium profile — formulated from real metabolic data, not a marketing department's best guess.

  • Six ingredients. Maltodextrin, fructose, sodium citrate, sodium chloride, potassium chloride, magnesium citrate. Unflavored.
  • Dual-source carbs hit independent transport pathways for higher absorption above 60 g/h.
  • Your config code printed on the label — burn profile, ratio, electrolyte balance.
