Muscle preset is another thing the cerebellum does. It is when you are about to perform a task and you “preset” your muscle to a particular strength
An example would be when you go to grab a carton of milk from the fridge but you can’t see how much milk is left so you go to pick it up thinking it will be super heavy but it ends up having close to nothing in it but your brain “preset” your strength for in case it was full
You basically just guess that it was full and make sure you are prepared to lift the heavy milk carton but are surprised when it weighs pretty much nothing
