When we practice football juggling, the increase of the number of taps gives a sense of accomplishment. Of course, juggling itself is a good exercise. But if we want to improve our soccer skills by doing juggling, just increase the taps is not enough.
I think adding a twist to juggling is very important. For example, I practice juggling within a circle which I made by placing a jump rope on the ground.
This is one of my YouTube short movies. As I shot this video in a rainy day on the soil ground, my soccer uniform and soccer boots got very muddy. But surely, my ball control skill was improved by this weird training.
