It's easy to ignore them.
Yet they are one, if not, the most important part of your body when it comes to basic human skills.
You'll notice that very few people actually spend time warming up this specific area of the body.
Let's not forget about rotations. This is also something that everyone needs to be doing well in order to function.
So in short, the feet and rotations are an essential part of general movement.
Taking care of them is at the top of the list when it comes to calisthenics training, as well as long term, holistic health.
So don't forget to do use these movements next time you warm up!
