Over the years which punches have been proven most effective for southpaws?
So the straight left cross punch is proven for sure. Its the number one punch for southpaws.
I see cuban southpaw boxers use a long range lead right hook that comes diagonally down, to great effect, or just a lead long range right hook coming across horizontally.
The rear hand left hook seems to be proven guys like Corrie sanders use this to great effect.
The lead hand right hook again very powerful and useful.
Any other punches that are either high % for southpaws or that you think will be high % in time?
