Lateral Drop?

[naturalchampion]

I was watching some videos and the lateral drop not only looks impressive, but also very useful. I was wondering a few things about it.
1. Is it hard to pull of?
2. What muscle groups are most assistful for it?
3. What are the most common mistakes attempting to execute it?

4. Is it as useful as it appears?(I.E Videos show it pretty much winning the match)
5. Any ways to practice it without a sparring partner?

1. Is it hard to pull of?

Depends on who your wrestling, if they expect it, and if you do it right...

2. What muscle groups are most assistful for it?

Shouldn't matter, its a finesse move, not a muscle move.

3. What are the most common mistakes attempting to execute it?

Not waiting for your opponent to pressure back into you.

4. Is it as useful as it appears?(I.E Videos show it pretty much winning the match)

Sure, if it's done right. But if the guy fakes pressure back in knowing its coming he will pin you instead.

5. Any ways to practice it without a sparring partner?

Sure. You practice the same back step and hip rotation but without a team mate there.
