Many people (men in particular) don’t like yoga. I’m a fan. Since starting P90X in January of this year, I’ve increased core strength, balance and flexibility. It complements any exercise regimen. Also, I’m fully convinced that, without yoga, one is very likely to get injured at some point when exercising. The stress just builds and builds with resistance routines and yoga helps offset that.
I’m also convinced that yoga gives you a good indication of how “in balance” your body is with itself. What do I mean? Well, you can curl, press, pull and squat your way through building strength. But people like doing what they know and are comfortable with. So the risk is that you focus too much on one area to the detriment of the other. In my experience, if one part of your body lags another in terms of relative fitness, your body over-compensates when engaging in sports-related activity. Injury often follows. To get in and hold all those annoying yoga poses requires that your body is fit enough–everywhere–to support itself: it’s “in balance.”
So do your yoga people.
