It was suggested to me to post this here so I will give it a go.
My squat has been lagging strength wise compared to my other lifts so wondering if it is technique. If I rule that out then it is probably a mental block going on.
Here goes.
I ran out of space on my camera so only one squat was videod from the back.
Look at the sticky at the top of the questions. It is discussed at length there.
