Regulate
Practice one deliberate physiologic response before narrowed attention becomes narrowed action.
- What you need
- Wearable or pulse oximeter · box-breathing guide
- First action
- Find a stable starting heart rate
Listen. Follow the count. Notice the response.
Start the guide. Follow Victor through baseline, four cycles, comparison, and reset.

Before you begin, place your wearable or the station pulse oximeter. Let the reading settle. Find a stable starting heart rate. There is nothing to enter or save. Just notice the number.
Settle into a comfortable position. If you become lightheaded at any point, stop and return to normal, comfortable breathing. You will complete four cycles. Each phase lasts four seconds.
For each cycle: inhale for four, hold for four, exhale for four, and hold for four. Complete four cycles, then return to normal breathing.
Let the monitor settle and find a stable post-exercise heart rate. Compare it with your starting rate. A ten-beat-per-minute reduction is a challenge target—not a test, a requirement, or a promised effect.
Remove the pulse oximeter if you used it. Return the device or display to its starting state. The exercise is complete.
- 01Baseline
Find a stable starting heart rate.
Use your own wearable if available or the station pulse oximeter. Do not enter or save the reading here.
- 02Breathe
Complete four comfortable cycles.
Inhale for 4. Hold for 4. Exhale for 4. Hold for 4. Repeat for four cycles.
- 03Compare
Find a stable post-exercise rate.
Notice the response. A 10-bpm reduction is a challenge target, not a test, pass requirement, or promised effect.
