Track
Here is a comprehensive list of what I track
Blood testing including Complete Blood Test, Lipid Profile including Apo(B), Morning Fasting, Hba1c, Uric Acid, Routine Urine, Liver Profile, eGFR. Occasionally I test for heavy metals
Hand Grip, Body Fat, Body Composition, Lung Volume
Breathe In & Hold, Breathe Out & Hold, Number of Breaths per Second
Total Time, Movement During Sleep, REM, Deep Sleep
Exercise
The human body is built to move, so move!
I track the total time I exercised, my heart rate while I exercised and the calories I burnt. The calories are usually inaccurate. My watch over estimates my calorie burn though it has gotten better over time. An hour of walking would show a calorie burn of 400 calories. Nowadays that is closer to about 150-200.
