Something obvious that bears repeating
You don’t just squat to get stronger. Or gain muscle. You squat to be able to squat.
You may go weeks without be able to lift a kg more than you are able to.
Or weeks without being able to lift a single repetition more than in the session before.
You may squat for years without seeing your quadriceps get any bigger.
But squat you must simply because it is a capability worth fighting to maintain as a biped homosapien.
And it also goes without saying that pulling, throwing, pushing and carrying are all capabilities worth having.
