Learn to Block
Wii Boxing is arguably the most physically demanding of the "Wii Sports" games, which has you frantically moving your arms to block and punch until your opponent stays down. A good way to prevent your opponent from landing too many hits and conserve some energy is to master the art of blocking. Holding both the Wii remote and Nunchuk vertically and tilting them both inward will allow you to block shots to the head, while holding the controllers parallel to the ground and tilting them inward will block body shots. To dodge, you hold both the Wii remote and Nunchuk vertically and tilt them both either to the left or right, depending on where you want to dodge.
Don't Swing Wildly
One of the common reasons why many Wii Boxing players fade after a couple of matches is because they don't play the game with any kind of restraint. Many people flail their arms up and down, in and out, and hope that their punches land. Often times, this will make the player tired out and unable to react quickly enough to take advantage of openings or, more importantly, block and counter their attacks. To avoid fatigue, have some restraint and pick when to punch. This will both conserve your energy and do more damage to your opponent.
Silver Gloves
After putting in the hours climbing up the ladder to get to the top of the Wii Boxing mountain, you will square off with the Grand Champion, Matt. Don't let the rather pedestrian name fool you--Matt can wreck you in a hurry if you aren't at the top of your game. Once you beat Matt, you are rewarded to the elusive Solver Gloves.
After you beat Matt, go into a match. Once the screen goes black immediately before a fight, press the "1" button and hold it down until the match begins. These gloves have no benefit to the player other than looking cool, but you can show them off to your friends.
Punches
There are three different kinds of punches in Wii Boxing: jabs, hooks and uppercuts. Jabs are quick and do little damage, but can render an opponent helpless if you keep at them. To perform a jab, hold either the Wii remote or Nunchuk vertically, then quickly thrust it forward. To perform a body shot, do the same motion with a downward tilt.
To perform a hook, hold either the Wii remote or Nunchuk vertically, as you do for a jab. Now turn your wrist so that the Wii remote or Nunchuk is horizontal, parallel to the floor.
An uppercut, which is the slowest but most powerful strike, can be done by holding the Wii remote or Nunchuk vertically and thrusting upward in the same motion but in the opposite direction from a body jab.
