Well, I have to put in my 2 cents   heh
 On Fight Science,  Those results were not very accurate to describe relative 
arts forces.
 For one reason, the chinese guy was short and not hugely bulked.  Whereas the 
boxer was much bigger, taller, bulkier.    
 The chinese guy threw a 'short range punch'  from about only 7" back...  whereas
the boxer threw a full-cockback strike.   
 The Kungfu guys power supposed was arroung 600lbs of  force.  The boxers 1000.
However, what would have happened should the KungFu guy been as big as the 
boxer in mass?  My guess is that the Kungfu Strike would have been superior 
if not the same as the boxers strike.    One thing about short range power,
is that is more usefull and less likely to be blocked,  because its not 
"Telegraphic".  You cant see it comming like you can with some wind-up
swing motion. 
 The ninjitsu guys 'Dim Mak' strike is also a close range strike, and they failed to mention the
forces at work.  They simply stated that the forces were that of a 35mph car
crash.    KungFu also has Dim Mak, tho maybe this guy didnt do it, or they chose
to only show the ninjitsu guys version.

 As for Shaolin Goju..  I did a search quickly.   It looks like BS to me.   For one, 
Shaolin is from China.   The site that showcased this style.. was Japanese!
(Karate)    
 From 
www.gallopskarate.com/about_shinjimasu.htmlBrief Timeline of Events
1890    Kanryo Higaonna introduces Naha-Te and a breathing exercise called Sanhin
1927    Chojun Miyagi founds Goju Ryu Karate
1930    Gogen Yamaguchi establishes Japanese Goju Ryu headquarters in Tokyo
1953    Shaolin Goju is founded by Grandmaster Charles Dixon
1959    Peter Urban introduces Goju Ryu to the United States
1960    Anthony Mirakian brings Okinawan Goju Ryu(Meibukan) to the United States
1973    Ron Van Clef forms Chinese Goju 
 To me, This is sad.   The art was formed at 1973,  by a non asian... whos credentials
in ANY system cant seem to be found.    Most likely a westerner, who tried to 
learn some chinese are overseas.. and was most likely, given the dillluted
and incorrect versions of the Real techniques.  Chinese were not big on
sharing thier secrets to forigners.   If forced, or were trying to be nice,
they gave out litteral BS.  Some functional stuff, and some that was all
wrong.  And missing the very potent  'Keys'  to making things
powerfull and effective.
  In fact, I believe much of Karate was formed by this method.  Japenese
trying to watch and learn KungFu stylist, and figure out what they were
doing...  OR,  were actually taught (forced), and gave out the BS.  
As Karate is super watered down BS compared to Any version of
KungFu.

 Next, I will comment on your Schools (kickboxing) training methods...
 To throw a person into sparring the first day..  seems ultra BS.
 That lacks any responsibility at all.  Its mindless, and shows poor
skill levels in teaching and depth of knowledge.  A student needs
a proper foundation before going into battle mode.  Id be willing
to bet that there are countless injuries that occur when newbies
arrive.  Some of these poor guys will walk away, try to heal, 
and never return.
 That and the way thay they conditioned is not good.    Its better
to 'gradually' condition rather than to just smash limbs. 
(thats later) 
 Improper conditioning can be a real problem.  Can cause much more pain 
and complications as the bone may get built up unevenly.
 ***
 BJJ is good for certain situations..  however, not in many real
fights.    For example,  for multple attackers, it will fail very 
quickly.  As you cant roll on the ground with one guy when the
others will be  there stomping thier feet into your head.
 It also lacks a 'Safe'  and skilled entry system.   It goes on 
the principle that you should be able to dive in past a 
strike.     The problem is, is that a human strike can move
faster than a Cobra strike (Fight Science)  at something like
40 feet per second.   Basically, its a split second.
 However, to move your entire body and dive at them 
requires much longer than a split second.  As you cant 
accelerate that much mass that quickly.  It opens the 
possibility that youll take a Serious blow to the head or
neck.. which can be severe to fatal.

  For a workout, getting in shape and losing weight.. I think
boxing would probably be better.   Less sensless injuries overall,
and maybe more usefull skills learned.
 However, I personally chose to learn  Wing Chun.   A 
Chinese close range combat system.   It uses an
advanced system of developement that allows one
to have a 'Safe' entry.   
 Some big Features in the style:
- Combination of Soft and Hard techniques, that you adjust on the fly.
   (able to defeat larger stronger people by using soft techniques)
- Use of "Dual hand" Simultainious techniques.  
Can Even attack with 3 limbs at once.
 (IE:  One hand Intercepts(Blocks),  other punches, and one leg Kicks 
low twords the attackers legs or knees)
- Incredibly Fast and Effecient.   Over 2 hits per sec,  and each 
strike over well 200lbs of force each.  Very little energy needed
or expended.. as it uses economy of motion. (not so 
good for weight loss  heh) 
- Insane Offensive and Defensive ability.  Use of two hands to 
breakdown gaurds, trap limbs, and enter smart and safe.  
Ability to intercept attacks and attack at the same time.  If
a limb gets by, its intercepted with the rear 'backup' hand.
 Ive gained quite a strong ability of WC in my past.  Ive long
since been out of it tho, as I have too many interest, and not
enough time.   
 At my highest level,  I was able to take on high level 
belts, even instructors, and make them look bad.  They 
barely could touch me.. and I was scoring constantly.
 The style is so much more advantageous...  that I was 
able to defend myself very well with a single hand at times, 
when I got board of the lack of challenge.
 The accuracy, speed and power generation were insane.
I was able to stop my fist from a full speed attack, when a
poor attacker was accidentally charging in twords it,
thus great control of accuracy.  
 As for power..   I tried not to utilize it.. unless someone 
got too cocky and or used too much power against me.  I also
always warned them many times.    I was able to Dizzy 
3 highly skilled artist with a short range strike, at only
liike 1/10 the power available.   Upon which time, they 
needed 5 mins to recover. 
( 2 jujitsu grappplers, and one Capoera/Kook Sul Wan  guy)
 Also, a really persistent --I'm attempting to get by the auto-censor and should be beaten after I re-read the rules-- pushed me too far, and 
after too many warnings,  I decided to give him a little
'''taste"  of what I was capable of.  
 He would always rush into my strikes, then plow me into
the ground.   I always told him,  those strikes would have
knocked him out, or broken his legs.  He never yeilded.
 One day, we sparred..   "Fight" ..   and he takes one
step twords me.  I immediately target his Knee with my 
Knee Stomp Kick.   The kick is send, and lands as soon 
as his leg touched the floor.   I added just a tiny bit
of Snap force.    He went down.  The fight lasted exactly
1 second.
  He Stayed on the ground 
grasping his knee in Tears.  Didnt get up for 7 minutes...
and then hobbled the entire night.   Told me it was even 
worse after his adrenalin wore off later that night..  almost
hospital worthy.   We are still on good terms however, 
and he now is very carefull of knee strikes 

  As well
as now using the strike himself   heh.
 Lutus, After you get to a decent level of shape and want
to progress in a much more skilled fashion,  I highly suggest
looking to take up some Wing Chun classes.   There are
a few branches..  Some are called  Ving Tsun... and some
have other alternative but simular sounding names.
