When you're playing the Punch-Out!! games and you haven't yet learned how to bob and weave properly, you're going to get punched a lot.

Which means that you're going to be knocked out pretty quickly unless you do something.

But what?

You do have one secret weapon.

Once every match, when Doc's giving you his pep-talk, you can hit Select. His fist will start pumping faster, and when you get back into the match:

Boom! Health Boost!

The amount of health you get appears to be random, sometimes you get a little sliver back and sometimes you get nearly the whole bar back. It's less reliable than I'd like it to be.

And if you do it before the match starts? Then your health gets halved. Good for a challenge, I guess.

And this does work on the Wii version. Plus the amount of health you get back has been normalized, making it well worth your while to do this trick every chance you get.
