How to build a coaching drill library that gets used

Most coaches have a drill library. It is just scattered across a battered notebook, three phone photos, a half-remembered session from a course in 2019, and the inside of one coach’s head. That is not a library. It is a memory, and memories do not survive that coach leaving, or you trying to plan a session at 9pm on a Sunday.

A drill library is only worth building if it gets used. Here is how to organise, write and maintain one so it actually shapes what happens on court, week after week, across every coach in the programme.

Why most drill collections rot

Three things kill a drill collection. First, it is scattered: a bit in a notebook, a bit in a chat thread, a bit nowhere. When you cannot find a drill in ten seconds, you default to the same five you always run. Second, it lives in one coach’s head, so the moment they are off, the quality drops and nobody else can teach the session the way it was meant to be taught. Third, even the good drills are never rewatched, so players forget the pattern between sessions and you spend the first ten minutes re-explaining instead of coaching.

The fix is not more drills. It is structure, clear writing, and a habit of keeping the thing alive.

Organise by skill, then by assessment pillar

Start with how you will look things up under pressure, because that is when you will actually use it. Organise drills by theme or skill first: net play, defence, clears, movement, serve and return. That is the obvious cut.

The cut that pays off most is organising against the same pillars you assess players on. If you score players on a six-pillar framework (technical, movement, tactical, physical, mental, match application), tag every drill to the pillar or pillars it develops. Now assessment feeds straight into session content. A player comes back weak on movement and recovery, and instead of staring at a blank page you pull the movement-tagged drills and pick one. The framework you use to judge a player becomes the index you use to coach them. That is the loop that makes both halves more useful.

Write a drill so any coach can run it

A drill in your head is worth nothing to the coach covering your Tuesday group. Write each one so a colleague can pick it up cold and run it the same way you would. Four parts do the job:

1. Set-up. Court layout, feed, number of players, where everyone starts. Concrete enough that there is no guessing.
2. Coaching points. The two or three things you are actually looking for and cueing. “Split step on their contact.” “Racket up early.” This is what stops a coach just feeding shuttles and keeps them coaching the objective.
3. Progressions. A harder and an easier version, so the same drill stretches a strong player and an improver. Change the constraint, the target, the court size or the feed.
4. The constraint that makes it work. Most good drills hinge on one rule: the cross-court is dead, the rally must reach six shots before anyone attacks, the feeder only feeds to the backhand. Name it, because it is the thing that makes the drill teach what it is supposed to teach.

Get those four down and the drill survives contact with a different coach, a different group, and you in six months. This is the same discipline that makes a session plan something you can coach from rather than a vague list of activities.

Use short video so players rewatch the pattern

Words describe a drill. Video shows it. A short clip, 20 to 40 seconds of the pattern run cleanly, does two jobs at once. It keeps the programme consistent, because every coach demonstrates the drill the same way instead of improvising. And it lets the player rewatch the shape between sessions, so they walk on court already knowing what the drill is for. You spend less time re-explaining and more time coaching the thing.

You do not need a production crew. A phone on a tripod, a clean rep of the drill, and a steady habit of capturing the good ones. Over a season that quietly builds into a genuine asset, especially for juniors who learn faster from seeing it than from hearing it.

Tag to pillars and goals so the right drill surfaces

Once drills are tagged to pillars, take it one step further and tag them to goals. A player’s development goal might be “tighten the straight clear to length.” The drills that serve that goal should surface when you open their plan, not when you happen to remember them. Tagging turns the library from a pile you browse into a tool that hands you the right drill for the player in front of you.

This is where a good drill library stops being a reference and starts being part of the coaching loop: assess, find the weak pillar, pull the tagged drills, plan the session, deliver, reassess. The library is the hinge between knowing what a player needs and doing something about it. It is also why the badminton coaches we work with lean on it most, and you can see how that joins up in our badminton coaching software.

Keep it living, not a dusty document

The biggest mistake is treating the library as a project you finish. You do not. The best libraries grow by a drill or two every week. After a session, add the variation that worked, write down the constraint you stumbled onto, retire the drill that fell flat. A quick note while it is fresh is worth more than a polished write-up you never get around to.

Do that, and a year in you have something no single notebook ever becomes: a shared, searchable, video-backed library that any coach in the programme can run, tied to how you assess and plan, and getting better every week. That is a drill library that gets used.
