Boxing instructional ?

I have a heavy bag and some gloves. I'm looking to use it for exercise/conditioning but I'd like to actually have proper technique and combos. Is there any DVDs that can give me some basics? 

Don’t need DVD’s, just YouTube basic bag work 

DVD’s are dead bruh. You Tube is all you need there’s literally a dozen decent sites teaching bag techniques and routines

I have all of these and agree.

Plus the work as a great sleep aid as well.

I don’t mean that as an insult just old boxing videos always a little dry.

Well wait Russ Anber is fairly animated.

Holy shit seeing those kids move on the Kenny Weldon video remind me of just how poor our outclassed I am.

And Kirik’s link is a good one too. Freddy Roach is an alright trainer.

Eddie Futch used to say " only suckers get hit with a right "

Freddy roach basics learned me a lot about footwork

I’m sure that Eddy said that and meant it, but in my experience, a good right hand beats a good left hook almost every time. If that statement is true, then folks like Wilder, Klitschko, Hearns, Foreman, Schmelling, etc have proved that there are a lot of suckers.

But Futch forgot more about boxing than I ever knew.
