Sean,
Here's a quick breakdown for you...
THE SET UP
1. Keep your head up and eyes on the horizon, not on the floor in front of you. The latter makes you drop your chest and round your shoulder (0:05).
2. Actively push your chest out at the start of the hike pass while keeping your head up. You are lifting your hips up. You can do this with the lighter weights. It gets harder with the heavier ones. Also, by pushing your chest out, you can let the bells travel further back underneath you, creating a bigger stretch on the hamstrings. This creates a more powerful concentric and makes it easier to get the bells into the rack.
THE GRIP.
The Pistol Grip is used by many GS competitors. I don’t think StrongFirst actively advocates it. Use the Inverted V as an alternative. It allows you to keep the chest up and keep the lats engaged on the backswing. It also makes the bells practically “roll” up into the rack on your cleans.
THE SQUAT.
Initiate the squat by bending the knees FIRST, then breaking at the hips. You’re breaking at the hips first. This makes you lean forward, rounding over at the shoulders and tucking your tail (it looks like) in the bottom.
Think about squatting “down” with a big chest between your legs and not “back.” Think about squatting so your torso is “on top” of your feet. This should keep you more upright and make it easier getting out of the hole. Furthermore, as you squat, think about simultaneously pushing your knees forward and your hips back. This should shift the weight into your mid/fore-foot, which activates the hamstrings and gluts a little more, creating more stability throughout the movement and makes it easier to stand up.
There are a couple of other cues I could give you, but starting there I think would help you out. If you get stuck, ping me, we can hop on a Zoom call.
Hope that helps.
