Weightlifting is a sport of action. We want forceful leg drive, explosive hip extension, with aggressive pull under and turnover.
"Drop" and "catch", on the other hand, are passive.
We pull ourselves DOWN to the bar to beat gravity. It's a race between us and the bar to the floor. To win, we need to get under the bar as quickly as possible.
We punch our body DOWN under the bar in the snatch so that WE control the descent of the bar. The idea of "catching" the bar implies we've lost connection and are passively reacting to its descent upon us. What ends up happening if we merely "hold" onto the bar, as Coach B describes it, is our arms cushion and sometimes bend under the load of the bar crashing down on us. Instead, we want to actively and aggressively push on the bar.
The snatch balance with no dip, or snatch drop, is an exercise we teach in the Weightlifting Level 1 course as part of the skill transfer exercises for the snatch. It is a great exercise to teach and drill moving the feet and aggressively punching the body DOWN under the bar. It builds also confidence and speed. Do it every day you snatch!
A few points of performance to note:
1. Feet start narrow in the "jumping position"
2. Elbows are pointed down, putting the shoulders on external position.
3. Using the hip flexors, pull your feet UP off the floor and move them out to landing position.
4. While in mid air, aggressively punch your body down into the overhead squat.
5. The bar do not travel up by much or not at all. This not a push press plus overhead squat. Have a buddy hold a PVC pipe above your bar and don't hit it! (That's why Rich is standing behind me in the demo video)
6. Make sure to land flat footed and settle on the bottom before standing up.
7. In this variation, there is NO dip. More speed and aggression are necessary to make the lift than in a regular snatch balance.
