[QUOTE=ginosifu;1131846]I would have to dis agree with this statement. I have been teaching kung fu for almost 20 years. During this time I have seen 75%-80% of all guys who lift, lift wrong for CMA. It is not just about the size but more about the range of motion. When your upper arms and shoulder get more muscular, they lose range of motion. I spoke of it here:[/quote]
I’ve never noticed a loss of range of motion, ever. Even in upper echelon bodybuilders, many of them are quite flexible; certainly not less flexible that someone who doesn’t lift weights.
Can you give me an example of the area of motion that was lost? For example, someone who used to be able to do x movement/position and then bulked up and now can no longer do x movement/position.
There is no scientific evidence anywhere that increased muscle in the upper arms and shoulders reduces range of motion.
The rare exceptions to this might be elite level bodybuilders when it gets to the point that the actual mass is just getting in the way, but let’s not forget that almost nobody has the genetics to get there, not to mention the drug budget or knowledge.
A normal person with normal genetics is in almost no danger of losing flexibility due to muscle mass gain.
This guy certainly doesn’t have flexibility issues:

Nor does this guy:

And even if there was a loss in flexibility (there’s not), but even if there was, it would be a small price to pay for the benefits that added muscle has in a fight.
If any loss of range of motion occurs, it would occur around this level:

The only way to get there is with:
- the right genetics
- the right training
- the right diet
- the right drugs
So that’s not going to happen for most people, nor is it going to happen accidentally. It’s not like you lift weights and end up bulky the next day.
If someone has a healthy amount of muscle, such as this guy, there’s not going to be any loss of range of motion unless the person neglected their stretching or something while they were lifting weights:

But most martial artists aren’t even in that good of shape, so I really don’t think they have anything to worry about.
It is important to get proper lifting advise or training. Just to go and lift heavy weights cuz you want to get big and strong may not be good for your MA.
I guess let’s agree to disagree. Again, I’ve never seen a case where the addition of muscle and/or strength decreased MA performance.
