haha most of the vids you find are wrong, I can show you wrong technique.

there is one vid by nuttin fancy on you tube that shows the wrong way of doing it.

HOO MAN that's tough to watch!
That axe is sure jumping out of the cut...I would sharpen it if I were him! I predict horrible shin scars on that guy before long. Although I agree, splitters aren't very fun to buck with! I don't like chopping logs that are not well supported although sometimes you have no choice - once in a while you get springy green logs blocking a road or whatever.
Hannibal, one thing that makes my life easier is that my axes are literally razor sharp. I don't muscle the axe in much for chopping, I just keep them super, super sharp and let the axe glide on home.
It is sure work if you don't have your chopping muscles in shape (whatever muscles those are - I guess you would know better than most of us!) but like anything else if you spend half an hour chopping every few days it gets to be fairly easy.
I grew up chopping all the wood for an old, uninsulated house heated only by wood here in Canada so my aim is pretty precise, and my dad who never left that house and still heats with wood swings with an accuracy you wouldn't believe, and I am sure that makes things a lot easier.
BUT one thing I would like to mention:
IF YOU GET REALLY TIRED STOP!!!
I buried an axe in my leg very effectively one time after spending six or eight hours chopping. I got lazy and stopped sharpening the axe and then I got really tired and my stance got crappy - too close to the tree - and the axe I was using (too small for the project anyway) jumped cheerfully out and found something softer than wood to bite into!
Then we had to screw around driving into town and looking for a doctor who would patch me up for not too much money. I guess you wouldn't have that problem but the axe stuck in the leg part isn't any more fun than the driving around so skip that too if you can. Axes are dangerous tools and the smaller the axe the worse off you are - a full size axe generally won't hit you at all, it will hit the ground, a 3/4 like yours will probably wreck your foot and a wetterlings hunter will just about take your kneecap off - I know.
Anyway a bit of practice, a thinner bit and a razor edge (if used with appropriate care) will do wonders for you, I promise!
