Muscle memory is one of the fundamental things you should develop in order to get faster. It is extremely important, as it gives you excess to many other skills such as F2L look-ahead, predicting first pair, and many other important things.
No matter how many algorithms you know, or whatever fancy tricks you know, they will not be useful if you cannot recall them quickly and accurately during a solve.
Now you may be asking this question: “What is muscle memory and how do I develop it?”
Good question. I shall answer that now. Muscle memory is when you have done something repeatedly so much that it becomes second nature for you to do it without thinking.
For example, when you see a U perm, as a beginner you might think: ” Ok, this is a U perm, and I have to regrip and turn and blah blah blah…”
You get the idea. But when you have developed muscle memory, the process becomes something like: “This is a U perm” and you have already done the algorithm when you finish that thought.
So, as you might have already guessed from the definition of muscle memory, to develop it means that you should do the algorithm you want to develop. Repeatedly. Over and over again. That is the point of drilling algorithms. Drilling also helps improve turning speed.
So, I have said enough and will keep this short. When you practice, you should also drill algorithms, instead of just doing solves over and over again. That is how to develop muscle memory.
Thanks for taking the time to read this slightly longer post of mine, and I hope you have benefited from doing so. Do leave a comment if you have questions! 😊
