I don't consider myself a fitness guru or a professional trainer, only an expert who can explain agility to other people. There are lots of things that you can do to increase agility:
Try a different type of boot. Try a different size of shoe. You may need to train your foot for a longer time to get a more optimal performance. Get in the gym, or get out of your house and try some different types of training. Try some different exercises. Some people are better with squats, while others have more balance. I've worked with a guy who could barely walk in his own shoes. So many other people can't. You might have to make some adjustments in your training, depending on your body and its needs. I've heard some people say that they have problems with mobility, while others who can do squats have mobility issues. It's all relative. If you're looking to lose weight or just improve your overall health, you might be better off sticking with exercises that are more suited for you, rather than spending money on new, expensive stuff. 3. Why does it have to be so expensive? I could tell you about all the other books I've written, about how the cost is prohibitive and I've lost hundreds of thousands of dollars in the process of researching, writing, and selling my books.
