Episode notes
Start With Center Of Mass
- Alex assesses movement from center-of-mass outward: COM → global joint mechanics → local joint mechanics → muscles/tendons.
- He emphasizes that joint position dictates muscle function, so positional context matters first.
Joint Position Dictates Muscle Function
- Joint position determines which muscles will be recruited and how they behave.
- Fix movement positions first, because muscles respond to those positions rather than the other way around.
Train Production And Deceleration Separately
- Use simple push/push-back examples to identify sided movement biases and relevant drills.
- Train the side that must produce force and separately train the side that must decelerate or accept force.
