The Running App That Improves
Your VO2 Max

VO2 max — how efficiently your body uses oxygen while running — is one of the strongest predictors of long-term cardiorespiratory health. VO2Boost is the structured program, with a real voice coach, that actually moves that number.

The Problem

Knowing and doing are two different things.

Most runners know VO2 max matters. Few have a program that actually raises it.

🔁

Same route, same pace

Comfortable running maintains fitness. It doesn't build it.

📊

Tracking isn't coaching

Apps log your run. They don't guide it in real time.

💸

Subscription fatigue

WHOOP, Runna, TrainingPeaks — $80–200/yr, forever.

🎯

VO2Boost is the program

Science-backed intervals, a real voice coach — own it once for $14.99.

Key Features

Everything you need to
actually improve your VO2 max.

🎧

Real-Time Voice Coaching

Your coach talks you through every interval, triggered by heart rate — not a timer.

❤️

HR-Triggered Cues

Push too hard, drift too low — your coach calls it immediately.

170–180

SPM Metronome

Optimal cadence, built in — no second app, no second screen.

📈

Alternating 30-second bursts at VO2max and 30-second recovery. High reward, manageable fatigue.

High-density intervals for lactate threshold and VO2 ceiling. 13 reps of 30s work / 15s rest.

Zone 2 Endurance

The low-and-slow aerobic base work Peter Attia calls the foundation of longevity. Sustained, conversational effort.

Cooper Test

12-minute field test to establish your VO2 max baseline. Run once, know your starting point forever.

Early Feedback

From beta testers.

★★★★★

"Finally an app that actually talks me through Norwegian 4x4. The voice coach calling out my HR zones mid-interval is a game changer. I don't have to look at my watch at all."

— Beta tester, iPhone 15

★★★★★

"I cancelled Strava the week I installed this. VO2Boost does what Strava promised to do — actually coaching me, not just measuring me."

— Beta tester, Android

★★★★★

"The built-in metronome running alongside the voice coach is the detail I didn't know I needed. My cadence went from 155 to 172 SPM in two weeks without even thinking about it."
