1. You need to bring in your stance by an inch/inch and a quarter on each side. Keep the toes pointed out 30 degrees.
2. The bar looks too high. Are you sure it's just below the spine of your scapula.
3. Stand all the way up at the top. Proud chest. Take a big, big breath. Hold it in. This will help the collapsing/losing tightness you have on the way back up.
4. You are sliding into your knees. Instead, push your hips BACK. Bend over more.
5. You're rocking onto your heels to start the squat, and then you shoot forward so then you end up doing a good morning at the bottom when you come back up. You see it in the last rep especially. This is why you see your elbows drive up so much on the way up. Keep the elbows down. Proud chest. Stay in the middle of your foot throughout the entire lift.
