Knowing that it takes a bajillion repetitions to master a technique, it might seem a little silly to do a few reps here, a few reps there of a technique. I fully believe there is validity to even practicing a move even just 15, 20 times after class- or even killing time before class.
A lot of jiu jitsu, in addition to physics and body mechanics is a lot about muscle memory- and we all know the more time we can dedicate to building that muscle memory, the better we should become at certain techniques and allow us more mental bandwidth to keep an eye out for the opportunities to use said techniques.
The nice thing about building this muscle memory is that it is not necessarily something you need to dedicate large blocks of time towards creating. It really is something you can take small “bites” with: a few reps here, a few reps there- it’s all with the intent of building a good habit essentially. We all know good habits don’t suddenly appear, that it takes time and consistency, and that same approach should be taken with jiu jitsu.
While we should still take larger pieces of time to drill specific things in order to get really in depth and work out the kinks (so to speak), I still feel there is definite validity to taking advantage of some time and doing a little extra drilling of some techniques.
Just my thought on the matter. Have a great day everyone!
