It's commonly agreed among trainers and strength coaches that the squat is by far the most technical of the big 3 lifts. Normally I find the most detrimental part of the lift is the initiation of the eccentric phase. Below I break down a couple flaws that I constantly see in self-taught lifters and provide some emphasis on what you should really focus on to end up in the most advantageous position.
Happy squatting,
