Some real gems here! More precisely:

1) Kids will only move as much as their parents do.
2) Train your diaphragm. It is the most underrated and underutilized muscle you have.

5) Establish full range of motion before you start building strength.
6) Weight train for your metabolism.
7) Do cardio for your mental health.
8) Walk for your longevity.

31) The don't need to deadlift 600 lbs but you need to work your posterior chain.
32) There is little benefit for running >3x/week. Skip a few runs and add in some resistance training.

34) Take your shoes off and walk outside more. Start with soft and uneven surfaces to strengthen your feet and ankles.
