Training is different than practice which is different from study. Practice is the getting into the flow of qi. And study is the intellectual practice of deepening an understanding.
Training is the repeated movement (mental or physical) to improve one’s practice. Training is the part where you get to push your limits and become better at it. An example would be doing a horse stance and throwing punches hundreds of times, constantly reviewing and improving each part of the movement. In a sense, the boring part of practice. Like doing musical scales. It gets you prepared for practice. This lets your muscle memory take over so you can learn how to flow with qi and then you can practice a punch in a form or even in a single movement but your ability is much better.
Practice is the time where you can get into the flow. Some call it getting into the zone. It is when you are completely, or mostly, totally involved with what you are doing. It would be ‘practicing’ the form or sparring.
Study is the reading of materials, listening to lectures, watching YouTube (even the bad videos can still teach you a lot), listening to podcasts…. All of these help you better understand what it is that you are doing. Some don’t like the intellectual aspect of learning an art form. But it widens your ability in your practice. For example, you might have a powerful punch, but after you study anatomy, physics, and psychology (even a little bit) your power will grow because you will know how to align the body with more efficiency, perhaps use gravity better, and play with your opponent’s mind.
We need all three parts to develop a deeper ability in our chosen arts.
Blow is a simple qi gong practice you can do anytime and any where. You don’t need a lot of space.
