Isolated Buzzsaw
Isolations are all about getting in front of the beat. With the buzzsaw (probably the easiest move to isolate) you only need to do a quick skip in the beat with your hands to get in front then simply keep the timing going. The feeling is very much akin to peddling a bike, but with your hands. Practicing in front of a large mirror or window helps a lot as you can see what is going on from the outside and adjust accordingly. Once you have nailed the way it feels stop looking at your reflection and do it normally or you will struggle without a mirror in the future.
