In my opinion... and please view these as 100% positive.
- Less thinking about it. It took you 30 seconds to get set-up. The bar isn't moving. Get under there, walk out, squat. boom!
- Sit back a tad more, drive off your heels and drive toward the outside of your foot. On a rep or two you can see your heels come up. No good.
- More glute work. Do you do glute bridges? Have access to kettlebells? You need to get your posterior chain firing and line, and you'll be set.
Good work bro...
