Beginner Exercise 1 - Learning ranges
The most important part of poking is making sure you're at the furthest possible range to best take advantage of these moves. The below exercise will help you get a feel for these ranges, it's a good idea to do this for all of your moves but for now long range attacks are the focus.
Hop into training mode and pick a move you want to practice.
Land it a few times and get a sense of how far it reaches.
Move well out of range and then try to get as close as you can to hitting them with it, without it actually connecting. Keep inching forward until it eventually connects. This is the optimum range.
Repeat the last step until you can reliably miss by a hair, take a small step forward and connect with it.
