I was reading through an article on bodybuilding.com about stretching do's and don'ts. (
http://www.bodybuilding.com/fun/stretching_types.htm ) Seems to me that there is a lot of confusion about stretching. I used to attend yoga classes 5 days a week. I loved the way I felt completely unbound and free of tension after each session. However, I have lived with back pain the majority of my life. Up until the past few years it was an ongoing chronic condition that would flare up and leave me laying on ice for a week. Since switching to mostly weight training now instead of yoga, I have nearly zero back pain like I used to. Now though, I am much tighter and feel bound up all the time. People are always saying "you need to stretch more" which I know to be a beneficial thing being that I am a CLMT, and personal trainer.
What are your opinions on stretching?
IMO, stretching serves no practical or functional purpose (except for the alleviation of the feeling of stiffness). The ONLY time stretching is at all advisable (again IMO) is post-workout. The only kinds of stretches that should be performed are active/natural stretches.
I have a different background than most people on this board. I am not a bodybuilder and 1. could never be one genetically and 2. don't aspire to be one. I was a Division I Wide Receiver in college and a Division I pitcher for my college teams. So my viewpoint of stretching is going to be different than most. Most of what I have come to learn and believe about stretching has come from working with numerous strength coaches and seeing all of their different philosophies as it relates to warming up and cooling down.
After 4 years of competitive college sports, I can honestly say that stretching does absolutely nothing for ME. In fact, stretching before many work outs or competitions has reduced my strength, speed and performance.
Here is the way I have begun to look at it: I look at my muscles as rubber bands in my body. Now, lets pretend you had three of the same exact rubber bands (muscles) that all started out the same size. someone tells you that you can stretch them out, warm them up or keep them the same size and they want to see which rubber band will travel the farthest distance and/or the fastest if you were to fling them. which kind of rubber band would you want. A) unaltered, short, cold B) one that is stretched passed its intended limit, almost to the point where the rubber starts to crack. or C)SLIGHTLY stretched by active movement and Warmed up
OK, now look at your muscle in the same regard:
A) sure this rubber band will travel well, but it would certainly travel farther if its molecules were warmed up and prepared to be stretched (by the actual movement, not stretched in preparation of the movement)
B) again the rubber band will travel, but you have elongated it so much, you have likely taken most of the spring/spryness out of the rubber band, thus eliminating its efficiency.
C) the obvious choice. you warm the rubber band up through active movements, however you are careful not to stretch it past its intended range. The rubber band is prepared to be stretched because the molecules are heated up and it will definitely travel the farthest.
I know muscles and rubber bands are not exactly alike, but they serve similar functions as it relates to athletic performance. So, again, IMO, stretching only serves to elongate the muscles. The elongation of the muscles places less stress on the surrounding joints because it is no longer "tight" and that is why people who stretch feel relief. So the whole question about stretching really boils down to what your level of activity is, what your fitness goals are, how important being pain/stiffness free is.
If you are an elite bodybuilder/powerlifter and you need to perform as efficiently as possible; you need the most weight and strength possible, stretching is not advisable. If you are a 45 year old man who works out to stay heart and mind healthy and has a stiff back, then by all means, please stretch regularly. comfort is key. But if sports/competition is your life, i'd stay away from the stretching and stick to warming up really well with natural movements and actions that will simulate the exercises you will perform.
