Stop comparing yourself to the 22-year-old with no kids, no mortgage, and 6 free hours a day.
Start where you are right now.
Building your body as a busy dad takes:
Consistency over intensity
Simple systems over perfect plans
Patience when progress feels invisible
Flexibility when life gets loud
A refusal to quit when it gets hard
Every strong, healthy father you admire started from zero.
The only difference between them and you is they started.
