First, all the sensor bar does is emit (infrared) light. The controller is what takes that data and transmits it directly to the Wii. (you can actually use two candles instead of the bar.)
As for the controllers reading, don't try real boxing so much as "cardio" boxing--more like aerobic kickboxing stuff. When you "real" punch, you make it stick, or drive through the target. But when you "cardio" punch it's more of a hit and bounce back motion.
What the controller actually reads isn't the motion of the arm, but the flick at the end of the punch. You could actually just flick your wrist at the right time to get it to read a punch--but then, that's not a workout.
