Left 🚫🚫🚫 Right ✔️✔️✔️
One of the most common mistakes I see in Olympic movements (snatches or cleans) is an inpatient second pull. This is usually thrown off by a bad start position as shown on the left with the shoulders placed too far back. Another mistake here, the hips shoot forward instead of up pushing the bar forward causing a jump forward. This will inevitably cause a miss with higher loads.
I got this cute from @jaredenderton
On the right, the shoulders stay over the bar longer and the hips ✴️✴️ UPPERCUT✴️✴️ the bar in an upward trajectory rather than forward. This puts more power into the bar for a much more efficient movement.
