How are combos used????

Hi all!

How are combos used??
Do you guys throw multiple shots hoping some will reach their target (hook, cross, hook)or do you set them up (jab, cross to make the guy's hands stay up and digging deep with a left hook to the body) Everything go so fast when you fight or both ways, or else.....How do you guys use your combos???? THANKS

Yes.

use leg kicks in a fight that the best thing you can do, hit them with some hard low leg kicks then jump in close for hooks or elbows
