I disagree. Lifting weights allows you to feel the muscle work against resistance and isolate it so that antagonists do not create tension. This antagonistic tension between muscles groups is what is defined as real tension.
Plus, weight training also increases your strength. Resistance training should be a part of everyone's fitness routine, period.
I'm speaking from a CMA fighting aspect here. Tension would most certainly not only be defined as antagonistic tension. Its just a difference in intent. Even isolated muscle force is against principle in many CMA fighting systems. Thats why weight lifting can affect your fighting, you become much less sensitive to smaller amounts of force as you are used to pushing through the force of the weights. Also, resistance training and weight lifting are two different things in my book.

All muscles work through contraction. Muscles do not do anything but contract and release. Thus, there is not a "soft" and "hard" way a muscle works. It just works. Softness is the coordination of muscle groups to move efficiently and in sequence with minimal muscular antagonism.
You do not lose flexibility by lifting weights. You feel tightness while you lift as the blood supply to the muscle goes up, and afterwards as you recuperate, but weight training does not affect the range of motion in a body part at all.
What you should be doing is stretching between sets to improve recuperation and increase circulation. If temporary tightness persists, it comes from overtraining.
I think you have misunderstood my usage of the word "feel" or "soft". Again, I'm speaking from a CMA standpoint where "feel" and being "soft" are the ability to sense the slightest amount of force from your opponent and yield to it letting it go the way it is forcing thus attacking from a different angle so to speak. I would completely disagree with your definition of "softness" at least from a mantis fighting standpoint. Your definition still allows for the force of isolated muscles which is against principle. Muscle force is what we look to avoid (in a force against force situation at least). The antagonism you are so fond of is moot as I'm speaking of all muslce tension.
Your correct that you do not loose flexability by lifting weights, your also incorrect. Of course I didn't say anything about flexability so I'm not sure where that came from, but since we're on it, let me explain myself. I've done alot of reasearch and study into the muscles of the body and body mechanics, as I'm working towards my master's degree in physical therapy I'm forced to

To be very technical its not the lifting of weights that decreases flexability, its the building of large muslces. And to be even more technical it doesn't decrease flexability at all, but increases the size of the fulcrum if you will. So while its technically correct to say weight lifting doesn't decrease flexability for all practical purposes it does. You are correct about stretching between sets which will help to combat this quite nicely, but building muslce affects flexability like it or not. You must work harder to keep or build flexability if your also building alot of muscle. "Tightness" has nothing to do with blood supply or flow. Its a byproduct of the muslces breaking down and building up. To label it as a product of increased blood supply would be a gross understatement.
Basically my point in this thread was to discuss this issue, I dont lift weights at all anymore, I do all bodyweight now, but I was curious as to others experiences with this issue.
