I started to appreciate side exercises a lot more in recent years. I think in our daily lives we do not do much to our sides often and neglect them. I like to think of it as we have eyes on the front of our bodies and so we tend to place more focus/emphasis on our front a lot more than our back or sides. With the side kicks, I think it is a good opportunity to establish some balance to our bodies and at the same time make your work out more varied. I think a balanced physical body translate to balance to the mental and emotional state. This makes your workout even more meaningful to know that your exercise can improve other aspects of your lives! Enjoy and practice more.
