I only ask this because people who didn't tend to not understand how to be aggressive or even understand correct footwork.
A good tracking method is working box to box movement. Something like times 2 is really good classifier to track for movement. Running it both left and right, Teaches how to preload and leave hard with a more than average entry. T
From there I would work on entry on different types of targets. I like working harder partials and small steel in practice to up the difficultly even though more than often you will have wide open targets to shoot into for most stages. Same goes for exists. Just work the same drill in reverse for ease of set up. I like to set up new array types each session to avoid working the same type of movement. You need to be able to move and enter/exit hard on any target array types. Movement doesn't need to be huge. I could get more detailed depending on division as that will change how aggressive you can/want to get with movement.
Track first reps to get a good sense if your baseline is improving or not. Anyone can run the same drill 10 times in a row and see improvements. Its all about that first rep. Just like on match day.
