Yes, Moore is apparently a 10th degree Black Belt now but he wasn’t back then. I agree that Bruce Lee’s Unstoppable Punch demonstration is not evidence that he was a great fighter. By the way what do you make of some of the physical feats Bruce Lee is alleged to have done, particularly the punch speed test?
This is my take on them all:
1. [SIZE=4]Lee’s striking speed from three feet with his hands down by his side reached five hundredths of a second.[/SIZE]
This claim was made in Jesse Glover’s book Bruce Lee: Between Wing Chun and Jeet Kune Do. I read the book. According to Glover this measurement was taken at his house with an electric timer. The speed of Bruce Lee’s punch translates to about 40 mph. By comparison Ricky Hatton, a professional Boxer, had his punch speed measured and had an average speed of 25 mph with a top speed of 32 mph. Muhammad Ali’s anchor punch against Sonny Liston was measured and the speed was about 42 mph.
I’m inclined to believe this one because Glover is a credible Martial Artist who went in to a lot of detail in his book. It’s too bad they didn’t record this one although you can tell Bruce Lee was fast by demonstrations such as the Green Hornet Screen Test.
So for this claim there is no proof but it is plausible.
2. [SIZE=4]Lee could spring a 235 lb (107 kg) opponent 15 feet (4.6 metres) away with a 1 inch punch.[/SIZE]
This one is definitely true. Bruce Lee’s One-Inch punch has been recorded on video and he did indeed send men flying with it.
3. [SIZE=4]Lee’s combat movements were at times too fast to be captured on film at 24fps, so many scenes were shot in 32fps to put Lee in slow motion. Normally martial arts films are sped up.[/SIZE]
This one is apparently true. I believe they addressed this claim in the commentary of Enter the Dragon which I own on DVD.
4. [SIZE=4]In a speed demonstration, Lee could snatch a dime off a person’s open palm before they could close it, and leave a penny behind.[/SIZE]
I don’t believe this one. I’ve never seen this demonstration and it doesn’t seem plausible.
5. [SIZE=4]Lee could perform push ups using only his thumbs.[/SIZE]
I haven’t seen this one but I have seen the one finger pushup so I’m inclined to believe it.
6. [SIZE=4]Lee would hold an elevated v-sit position for 30 minutes or longer.[/SIZE]
I’ve seen pictures of Bruce Lee doing a V-sit so I know he could do it. But for 30 minutes? That’s bull$hit. Gymnasts can tell you that is not possible.
7. [SIZE=4]Lee could throw grains of rice up into the air and then catch them in mid-flight using chopsticks.[/SIZE]
There’s no way Bruce Lee or anyone could do this. The rice would slip through the chopstick even if you have the coordination to grab it. And again there’s no proof.
8. [SIZE=4]Lee performed one-hand push-ups using only the thumb and index finger.[/SIZE]
This demonstration is on video so definitely true.
9. [SIZE=4]Lee performed 50 reps of one-arm chin-ups.[/SIZE]
After researching this I don’t believe the claim. The Guinness Book of World Records Holder for most one-armed Pull-Ups in one minute is George Gaydardzhiev who did about 17 in one minute. The video is on Youtube. Bruce Lee allegedly did 50. Consecutively with no rest? Not likely. And again no proof.
10. [SIZE=4]From a standing position, Lee could hold a 125 lb (57 kg) barbell straight out.
[/SIZE]
I would have to see this one to believe it. There’s no proof and common sense indicates that this is not possible especially for a man Bruce’s size.
11. [SIZE=4]Lee could break wooden boards 6 inches (15 cm) thick.[/SIZE]
I’ve seen Bruce Lee break boards but 6 inches thick?! That is unlikely. Where is the proof? And besides, boards don’t hit back. 
12. [SIZE=4]Lee performed a side kick while training with James Coburn and broke a 150-lb (68 kg) punching bag.[/SIZE]
That’s possible. Punching bags can be broken.
13. [SIZE=4]Lee could cause a 300-lb (136 kg) bag to fly towards and thump the ceiling with a side kick.[/SIZE]
No. There’s just no way that this could be done. And again no proof.
14. [SIZE=4]In a move that has been dubbed “Dragon Flag”, Lee could perform leg lifts with only his shoulder blades resting on the edge of a bench and suspend his legs and torso perfectly horizontal midair.[/SIZE]
I’ve seen pictures of Bruce Lee doing this so I believe it.
15. [SIZE=4]Lee could thrust his fingers through unopened steel cans of Coca-Cola, at a time before cans were made of the softer aluminum metal.[/SIZE]
Again, no. Yet again, no proof.
16. [SIZE=4]Lee could use one finger to leave dramatic indentations on pine wood.[/SIZE]
I’ve never seen it tried but I don’t believe this one either. And yet again no proof.
So at the end of the day a lot has been claimed about Bruce Lee with some claims being verified and some not. Many of these claims are preposterous. Bruce Lee was in great athletic condition. He was fast. He was strong. He was a human being and many professional fighters have met or exceeded his level.
