The overhand right is a popular punch in MMA, especially among wrestlers. This is because it is one of the most powerful punches that you can through, arguably the most powerful, and is a great strike for counter-punching. Chuck Liddell was one of the first fighters to really make good use of the overhand right, although Dan Henderson and Fedor Emelianenko do as well.
The idea behind the strike is to throw as much as your weight into an arcing punch as possible. The overhand is usually used to attack taller fighters, although it can still be landed effectively against fighters of equal height. It’s not recommended to throw it against a shorter fight; although it’s possible, you will lose some power.
Most often, the overhand right is not thrown in a combination. Instead, it is a single powerful strike often used as a counter. Shogun Rua, for example, knocked out Lyoto Machida with an overhand right as Machida threw a straight left. As far as countering goes, the overhand right is most effective at countering jabs or left straights. It comes overtop the opponent’s punch and lands on the side of their face. Due to the power of the punch, it is pretty easy to knock someone out with it if they are throwing a strike as well.
The main reason that the overhand right is so popular for wrestlers is that it allows them to close the distance with a strike. Since all of their weight is already coming forward from the punch, they can clinch up immediately afterward and initiate a takedown. Because of this, it is advised that you move for an underhook with your left arm just as you land the overhand. Don’t leave your head open as you throw the punch; instead, change levels and stay covered up until you’re close enough to tie your opponent up.
Getting good at the overhand right will require plenty of practice and a lot of working on your timing. Since it’s a single punch, timing is everything. You need to make sure you hit your opponent when his hands or down or when he is throwing a strike. An effective way to make your opponent drop his guard when throwing the overhand right is to change levels first as if you’re attempting a takedown, throw the strike as your opponent drops his hands, and then follow through for the actual takedown when he’s rocked.
Generating a ton of power is a factor of both technique and power. In order to increase your power, you’ll need to improve your overall MMA conditioning. Do independent research, read my articles, or adopt an established routine in order to do this.
