If you play @Steficohen’s squat videos with sound you’ll hear our teammates constantly yelling “ELBOWS!” Do you ever think about your elbows when you’re squatting? How to place them? What’s their role? How could they “damage” your squats?
Keeping your elbows neutral (down) is the best/safest way to squat: this because when you keep your elbows down, the bar’s load is evenly distributed perpendicularly on your body, placing most of the stress on your quads, decreasing the stress on your back as long as it’s being kept tight. You can also think about pushing the bar up with your hands as your elbows tuck down.
Instead, flaring your elbows backwards will draw the load forward aswell in an anti-clockwise motion, decreasing the stress on your legs, while increasing the stress on your lower back for you not to fall forward.
Always keep an eye on your elbows and make sure you keep them down & not back. Sure, lots of people are very flexible and can keep the load evenly distributed even with their elbows backwards, but, that doesn’t apply to most of us!
