HIITO2

HIITO₂ is a high-intensity, performance-driven LiveO₂ protocol that combines interval-style exertion with adaptive oxygen contrast to accelerate cardiovascular adaptation. It is designed to push oxygen utilization, aerobic power, and recovery speed beyond what traditional HIIT or altitude-style training can achieve.

Protocol Focus

HIITO₂ targets rapid performance gains by challenging the body to:

  • Utilize oxygen more efficiently under stress
  • Improve VO₂ max and aerobic capacity
  • Adapt quickly to changing oxygen availability
  • Recover faster between intense efforts

Who This Protocol Is For

  • Athletes and highly conditioned users
  • Users who have already completed Whole Body O₂
  • Individuals training for performance, speed, power, or endurance
  • Those seeking faster cardiovascular adaptation in less time
  • Anyone looking to perform at their highest physical capacity

Details

System/ Equipment Needed

LiveO2 Adaptive Contrast or LiveO2 Extreme (preferred).

Duration

Short, focused sessions designed for high stimulus with minimal volume; results compound over multiple weeks of strategic use.

Frequency

3-5 sessions per week, depending on conditioning level and training load.

Intensity Level

High to Very High

Primary Focus

VO₂max, aerobic power, oxygen utilization under stress, rapid recovery

Protocol Breakdown 

Utilizes intense work intervals paired with deeper oxygen stress to challenge oxygen utilization and cardiovascular capacity, followed by structured recovery phases that reinforce adaptation without excessive mechanical load.

How it Differs From

Standard HIIT

Unlike traditional HIIT, which stresses the system in a single oxygen environment, HIITO₂ layers oxygen contrast into interval work. This creates:

  • Greater metabolic stress with less mechanical wear
  • Faster cardiovascular signaling
  • Stronger adaptations in oxygen utilization and recovery
  • Recover faster between intense efforts
  • Greater performance gains in less total training time

What Users Commonly Experience

  • Noticeable improvements in VO₂ max
  • Faster recovery between sprints or rounds
  • Improved work capacity under fatigue
  • Enhanced performance carryover to sport or training
  • Higher tolerance to high-intensity efforts under stress
