I am not a sports doctor, but I do a lot of research on how agility training and exercises are best performed. I know that people don't think that there is any harm in trying these things out, even though there is very little scientific evidence for the health benefits of such exercises, and that a lot of money is spent on them. However, I would never tell anyone what to do, because there is no scientific evidence that suggests the specific techniques I am about to show you can hurt anyone.
The most important point to remember about agility exercises is this: there is no harm in them. The point of using the above agility exercises is to get the upper body working at an optimal level. Some exercises are better than others in terms of building agility, but the important thing is that the exercises are used at a level where they are at least possible to perform. For example, you may have heard that jumping is a good exercise for building flexibility and strength. However, jumping has only a few benefits, and you shouldn't do it in all situations. First, jumping exercises may not build much upper body strength.
