With all learning in general, it's best to take in a certain amount (varies by individual, test to see what works best for you), then relax and maybe put on headphones with music (while reviewing in your head what you just learned). This allows all the stuff you just crammed into your short term memory to make its way into your long term memory. Sure, an isolation tank is THE best thing for this, but I doubt any of us even have access to one let alone have one. Basically, you want to avoid adding too much new information (or distracting information) into your memory because it will naturally drop off some of the older information to make room (or assume that it wasn't important enough to save).
Of course, as with all muscle memory activities, repetition and actual use of what you just learned help considerably. Even just closing your eyes and visualizing the activity is beneficial because, in most things, your mind doesn't distinguish between imagining and actually doing something. You see this a lot with athletes and race car drivers, etc.
