It’s how well you know it.
As martial artists grow and gain experience they are often looking for the next new piece of info, the newest technique, the next drill.
In fact the opposite should be done. Strip away the excess, loose the junk and use the extra time to work on the things that really work.
Forget fancy, go for simple. Review the techniques and drills you have, are they of any use? Will they work for you in the real world? It will nearly always the things you learned when you were a white belt. Why do we get taught fancy stuff? Usually to keep students interested, that’s not completely true. Advanced techniques are necessary, but they should build directly on the foundation of the basics, they should be ways of making the basics more effective, not replacing them.
If strength and fitness are included in your training (and why wouldn’t they be?) then the problem is compounded further. Just open a muscle magazine or look on youtube for some of the weirdest exercises ever conceived. Things that do nothing more than waste time that could be better spent on more productive endeavours. The funniest are from the “functional fitness” people, but they will never be as functionally fit or strong as a grappler/boxer or strongman competitor who does non of the strange circus tricks often advocated (Bent over rows while balancing on a bosu ball anyone?)
Stick to the basics. Get results. End of.
