BJJ players are accustomed to using the shrimping motion (connecting your feet to the mat and moving your butt) to get their hips moving. That's a totally appropriate thing to do. However, the nature of the lockdown (outside foot on the inside of the entaglement) prevents that traditional style of hip movement. So, either you have to learn a new way to move or you get stuck.
However, by attaching your self to your opponent with the lockdown, you've effectivcely established a 2 on 1 situation against his trapped leg. That leg is a lever to his hip. Wherever his hip turns, his body must turn. By learning to whip properly and effectively, you can get to your side in an incredibly powerful and offensive manner.
You just gotta be willing to learn to move your hips in a new way.
Every Jiu Jitsu class across the globe does shrimps to start the class. They are practicing moving their hips in this way. Of course that seems like the easier way when they meet resistance in the half guard! How many reps have they got on shrimps? Conversely, how many classes are they opening by learning to move their hips with the whips? ZERO. So which style of half guard will they view as succesful?
