Have you ever wondered, seriously, with all the information about on how to do a lift (deadlift, squat, bench press...) how the very first person to do a weighted squat/bench press/deadlift, of the barbell variety, considered their technique?
Did they ever consider they had mechanical disadvantages? That they were performing it poorly, or even incorrectly?
Every time I see a person say the deadlift is difficult, or the squat has so much that needs to be taken in to account and learned before lifting, I always wonder what they would have done had none of the information, that is so abundant today, been around for them.
It's just an intriguing concept.
