I've been using my StrikeMeter again this weekend. For those who haven't seen the previous threads (or a refresher for those who have), it's a meter you attach to a standing target to measure the
relative impact when you strike. This isn't a scientific number like PSI or foot-pounds or anything like that. The number by itself isn't very useful, but can be useful to compare techniques used on a similar target.
This time, I decided to test the chambered reverse punch, the cross from the boxer's guard, and other similar techniques. For each punch, I did 5 tests, after which I dropped the lowest and highest score, and averaged the remaining 3. All punches were done with my right hand, wearing a boxing glove, aimed at BOB's chest.
- Body Motion Only: 286
- Right Front Stance: 432
- Left Front Stance: 516
- Boxer's Cross: 579
- Horse Stance Arm Punch: 620
- Ducking Cross: 647
- Superman Punch: 660
- Chambered Reverse Punch: 663
- Horse Stance With Hip: 670
- Lunge Punch: 702
- Bicycle Superman Punch: 810
Body Motion only was a punch done just for comparison. I extended my arm before the punch. Then I pivoted my hips into the punch. I'm honestly surprised it was as high as it was.
Right Front Stance and Left Front Stance indicate which foot was forward, in a typical Taekwondo or Karate front stance. These punches were purely arm punches. I'm honestly surprised that it was 20% stronger with the left foot forward, I didn't think that would make a difference. I'm guessing this is because your right foot is pushing straight into the punch in the left front stance, where your left foot is pushing at an angle to the punch in the right front stance.
I'm also surprised at how high the Horse Stance Arm Punch was. This is the same as the front stance punch: arm motion only. I'm guessing this is because both feet are engaged, while in most of the other punches, you're only engaging the back foot. This is also why adding the hip motion to the horse stance punch doesn't add much more power; because you're adding your core and getting more push from the right leg, but you're also taking pressure off of the left leg.
The boxer's cross is the punch from the guard position. The ducking cross is similar, except instead of aiming the punch down, I'm dropping my body down so I can punch straight into the chest. I'm not sure if it's the weight dropping, or the angle of the punch that makes this stronger than the regular cross. But ducking into it provided a roughly 12% increase in power. (And I haven't trained that punch nearly as much as the regular cross).
One thing that's clear is the chambered reverse punch (hand chambered at hip in a back stance, twist the hip like a boxer's cross) is stronger than the boxer's cross. I've heard claims that the boxer's cross is stronger than a reverse punch, and I think that is simply untrue. I'll circle back to that discussion in a minute. It is true that the cross is stronger than just doing an arm punch in front stance. But the horse stance punches, or the proper form of a reverse punch are stronger than a cross.
Last, we have the punches which use a significant amount of body weight. The lunge punch, superman punch, and bicycle superman. The lunge punch is the punch you see in many Taekwondo and Karate forms, where you step with the right leg and punch with the right hand as you land. It makes sense that this is the strongest punch on the ground, since all of your weight is being pushed into that punch (instead of a reverse punch or cross, where some of your weight is on your lead leg).
The superman punch (right knee up, right foot back when you punch) I think loses some compared to the bicycle superman, because your right foot is going back, which takes some of the power off of your right side. The bicycle superman (left knee up, right knee up and punch) seemed to have all your weight on the punch.
Coming back to the discussion of the boxer's cross. I'm not trying to make the claim that the traditional punches are better than the boxer's punch. The boxing punch has plenty of advantages over the chambered punches. It's faster, and it's an easier guard position. However, I think it's a complete myth that the boxer's punch is the
stronger punch, a myth I've seen in several discussions. Of course, a boxer probably trains more for punching, which results in a stronger punch...but that's going to be true no matter what style of punching is used.
Last thought, I forgot to do a lunge reverse punch (left leg step, right leg punch). If I remember, next time I will compare the two types of lunge and see if there's a noticeable difference. If it's anything like the front stance punches, there probably will be.
