Key takeaways

  • HIIT is potent but research shows diminishing returns past 2-3 sessions per week for most people (Laursen & Jenkins, 2002). More isn't always better.
  • The AI tracks your total high-intensity volume across all workouts - not just dedicated HIIT sessions. A hard CrossFit WOD counts.
  • Heart rate data from Strava or your wearable shows whether you're actually hitting the intensity targets that make HIIT effective (>85% max HR).
  • Recovery data from WHOOP or Oura determines whether your body can handle another HIIT session or needs lower-intensity work.

AI HIIT Coach

HIIT is effective but easy to overdo. Your AI coach tracks your training intensity and recovery to make sure you're getting the benefits without the burnout.

Intensity zone tracking

The AI monitors time spent above 85% max heart rate across all your workouts. This is where HIIT's benefits come from - if you're not actually reaching these zones, your 'HIIT' sessions may just be moderate cardio.

Session frequency management

Research suggests 2-3 HIIT sessions per week is optimal for most people. The AI counts your high-intensity sessions and flags when you're exceeding what your recovery data can support.

Recovery-based scheduling

HIIT creates significant nervous system fatigue. WHOOP or Oura data helps the AI determine if you've recovered enough for another high-intensity session or if an easy day would be more productive.

Progress tracking

The AI tracks your work capacity over time - are you able to sustain higher outputs for longer? Improving peak power, time to exhaustion, and recovery between intervals are all monitored.

Frequently asked questions

How does AI HIIT coaching work?

The AI tracks your high-intensity training volume across all your workouts using heart rate data from Strava and recovery data from WHOOP or Oura. It makes sure you're doing enough to see benefits but not so much that you burn out.

How many HIIT sessions per week should I do?

Research points to 2-3 sessions per week for most people. The AI personalizes this based on your recovery data. Some people can handle 4, others max out at 2. Your HRV and recovery trends tell the story.

Can I combine HIIT with strength training?

Yes, but order and spacing matter. The AI schedules HIIT and strength training to minimize interference. Generally, strength before HIIT on the same day is better for preserving strength gains, and 6+ hours between sessions is ideal.

Does it track different types of HIIT?

It tracks the intensity and duration of any high-intensity work whether it's Tabata intervals, sprint repeats, circuit training, or metabolic conditioning. What matters is the total high-intensity volume and your recovery from it.

Is HIIT good for weight loss?

HIIT is time-efficient for burning calories and research shows it can preserve muscle mass during a deficit better than steady-state cardio alone. But it's also hard to recover from, so the AI balances HIIT volume with your recovery capacity to prevent the cortisol spikes that can stall fat loss.
