I try not to lean forward, since I find that it causes me to push my punches. If you're a tall fellow, you should bend at your knees instead.

I also block left hooks with my glove on my cheek, often I roll with the shot (i.e. pulling my left shoulder back) and then throw a left hook of my own. In the heat of things I'll sometimes block by sticking my right arm which is bent in almost a 45 degree angle, which looks like something that you'd see in karate.

I don't like to lean away from hooks, but I like it when my opponent does. They lean away from the first hook, but I step in and the second one catches them.

You can also duck under hooks, again try bending more at the knees than at your waist. Always keep your eyes on them.

Anyways, here's a thread that I recommend reading: http://www.saddoboxing.com/boxingfor...u-get-hit.html
