I've written a complete article on agility training for people who don't want to read the whole thing.
A-Frame Agility is my favorite. My wife and I are doing a lot of it in our apartment. It's a good workout for most people. Some of the stuff you can get at Target is awesome. I got a set of 5-Star Performance Balls. I am also interested in Agility Training for athletes. Some people like a little more than others, so I have some different products I have tested. The ones I am selling for right now are: The Performance Ball, Agility Ball, Agility Stabilizer, Stabilizer, and Balance Ball. I have a few other products that I am testing. So, with that information, I am starting to see that some people like some of these products more than others. The problem is that not all people do the same things. So, we need to get to know people and find out how they react to each product, and find out what they really need. The first step is to see if a person will buy the product and then how many times they use it. A good way to do this is to use the product in your normal life and then see what they say about the product.
