Re: Physicist
What are you on about "arm mass"? I saw a similar article once prattling on about the weight of a fist......
Your technique allows you to put a proportion of your body mass in a strike. This is the mass that counts, not just the fist or the arm. This is why a 10 stone man can sometimes out punch a 15 stone man. With better speed and more use of what body mass is availabe, it can be done.

Force (N) = Mass (Kg) * Acceleration (m/s/s)
Work Done (J)= Force (N) * Distance (m)
This tells us that to increase the force of your punch you need to increase your mass or acceleration or both. So in theory a martial artist who had an arm mass of 10 kg and could punch at 10 m/s/s (100N pathetic but just an example) has the same force as a boxer with arm mass 20 kg and can punch at 5 m/s/s.
Therefore muscle mass is not the only factor in deciding punching strength.
As to weight lifting muscle being put on depends on 2 things weight and distance (direction also has an effect F * d (Nm) but thats not important). Lifting a high amount of weight a few times would give you high force low distance with the low amount of weight being the opposite. So it really depends how many times you can lift the lower weight compared to the larger one (work this out by counting how many heavy weight you can lift to exhaustion and then the light weight, with rest of course, and compare the 2). This will tell you which one taxes you the most.
(This dosent really have much to do with anything it just occured to me)
