Its not too hard really..

To land them in a competitive fight is more tricky then throwing them..

Things like one two left hook to the head left hook to the body work well..

Lead left upper, strait right left hook.. Then go to the body if possible..

right upper left hook strait right left hook body n to the head..

And of course mixing it up you can do three or more uppers to the body and work your way upto the head with hooks and more uppers

S'fun ..Lol
