Takedown mechanics and safety are equally important when trying to execute an effective takedown. Mechanics are important for effectiveness and safety considerations and practices are very important to prevent injuries.
Takedowns are found in many styles such as Chin Na, Judo, Wrestling, Jujutsu etc.
The mechanics of takedowns are similar if not exactly the same in all styles.
The LABEL of styles do not matter. The important thing is to slow down and study how the joints work.
And MOST IMPORTANT, do it at a speed where you DO NOT injure your training partners and friends.
