Consistency is the key.
Most fitness apps help you track workouts. This one helps you build the demanding habit of actually showing up—week after week, even when work explodes or life interrupts.

The protocol
Built on science. Designed for people.
Stop following surface-level monoculture fitness programs. Prioritize healthspan and stop chasing shortcuts.
5-6 hours weekly. Measurable outcomes. Years of life to gain. Building a body engineered for decades, not seasons.
Science
Research-Backed Protocols That Work
Longevity demands hybrid training. The25Percent integrates strength and cardiovascular modalities based on peer-reviewed consensus—not trends. Every protocol targets the biomarkers proven to extend healthspan: VO2Max, metabolic resilience, functional capacity.
Focus
Train What Actually Extends Healthspan
The25Percent focuses on the pillars backed by global research to extend healthy years. Zone 2 cardio, VO2Max intervals, functional strength, and accessory work. Every minute moves the longevity needle.
Momentum
It's about Real Life, Not Perfection
Complete 80% of your weekly volume and stay on track. Miss a day? Adapt—not restart. This is flexibility within structure. Built for adherence over decades, not short-term transformations. It's about real life, not perfection.
The week
A week in the protocol.
Three lifts, two Zone 2 sessions, one VO2max session, mindfulness daily — every week.
The program
Four pillars, built together.
Strength training
Three weekly sessions: compound lifts, progressive overload, structured A/B splits. Track done or not done, no rep counting required.
Zone 2
Structured sessions plus lifestyle volume count toward the weekly 150 minutes. Together they build your aerobic base and metabolic efficiency, the foundation higher-intensity work sits on.
VO2max
Norwegian 4×4 or 30/30 intervals train cardiorespiratory fitness, the single strongest modifiable mortality predictor. Every step up the fitness scale matters.
Mindfulness
Five short, structured sessions built into the training week, not a separate app to maintain. Stress integration that supports training adaptation.
