    2/ Here is my IHHT protocol:

    + 35 days total
    + 26 biofeedback training sessions
    + 3:1 rhythm: three training sessions,one recovery

    Cycle per Session (Biofeedback Mode):
    + 5 minutes training (hypoxia: SpO2 85→77%)
    + 3 minutes recovery (adaptive hyperoxia, 99% SpO2)
    + 5 cycles

    Starting a new protocol: IHHT

    + alternates low and high oxygen
    + igniting mitochondria and boosting cellular energy
    + raising red blood cells and repairing vessels
    + accelerating recovery and improving cognition
    + slowing speed of aging

    4/ Why This Matters:

    + Muscle volume and body composition are highly predictive markers for long-term health and longevity.

    + Muscle Mass (Volume) and Longevity: For older adults (>55 years), being in the top 25% for muscle mass reduced all-cause mortality risk by 19% compared

    1/ Breakdown of my body composition improvements over the past 9 months Oct 2024 → Jul 2025:

    Muscle Volume:

    Total (bi-lateral) thigh muscle volume: Increased by 0.4%, from 18.02 to 18.10 liters, placing me in the top 1%. While muscle volume typically peaks between ages 30-35

    2/ Muscle Fat:

    Muscle fat infiltration: Decreased by 23%, from 4.30% to 3.50%, putting me in the lowest (best) 1%. This significant reduction in muscle fat infiltration, alongside increased muscle volume, has greatly improved my muscle quality.

    3/ Body Fat:

    + Visceral fat: Reduced by 20%, from 0.70 to 0.56 liters, indicating a substantial decrease in the most harmful type of body fat. This performance outranks over 99% of men my age.

    + Subcutaneous fat: Remained largely unchanged at 2.68-2.72 liters, still within the

    Here are my MRI body composition results.

    Top 1% muscle volume.
    Lowest 1% for visceral fat.

    Changes over past nine months:
    ⬆️4% muscle
    ⬇️23% muscle fat infiltration
    ⬇️ 20% visceral fat
    ⬇️ 59% liver fat

    Get jacked.

    Muscles lower the risk of obesity, insulin resistance, fractures, and dementia.
