Comment Poll: Hardest Stage to Coach?

Coaches, be honest. Is it Red Ball, where you're keeping 5-year-olds focused?
Orange, the awkward bridge?
Green, where tactics and nerves arrive?
Or Yellow, where results start to matter?

Drop A, B, C or D below and tell us why. I'll share the most common answer and how SYSTEM-9 tackles it in a follow-up post.

Most junior programmes are a collection of sessions.

SYSTEM-9 is a pathway. It runs from age 4 to 14 across Red, Orange, Green and Yellow ball, with every stage building on the last, so you always know what comes next and why.

Save this for your next planning session and share it with a coach who's still making it up week to week.

Here’s your review:

Andy’s Find the Hole is a clear, practical guide to developing tactical awareness in tennis. The detective approach gives players a memorable way to read opponents, test weaknesses and build a purposeful game plan. I particularly like the emphasis on observing evidence rather than making assumptions, alongside exercises coaches can apply directly on court. A useful resource for coaches and competitive players looking to make smarter decisions during matches.

A book i hae been working on for my coaching staff and from when i worked in a secondary school for a year and a half with 30 kids on 3 courts is; 'Rotations': "Numerous Kids. 1 Court. Zero Queues."

Every coach has been there: eight kids, one court, and a line of players getting bored behind the baseline.

A queue isn't a session, it's a waiting room.

ROTATIONS shows you how to run any number of players on one court so everyone is hitting, moving and competing the whole time.

What's the most players you've had on one court? Tell me below…

In 2010, I sat down to write my first tennis book that took over 2 years.

I had no plan to write 32 of them.

But every time I stood on court, I saw another gap. A coach with 12 kids and one court. A parent who didn’t know how to help after a tough loss. A junior who wanted to go pro but had no map to get there.

So I kept writing.

16 years later, this is The Complete S9 Library.

Books for coaches, players and parents

Every book came from a real problem on a real court or was written to help my assistant coaches in my team.

Thank you to every coach, player and parent who has used them along the way.

Most players walk onto court knowing everything about their own game and nothing about the person on the other side of the net. They lose, shrug, and say, "They were just better today." But more often than not, that's not true. The opponent had a hole in their game, a backhand that breaks down above shoulder height, a second serve that sits up in the middle of the box, and nobody noticed.

Find the Hole teaches players to see it. Using the SYSTEM-9 Detective Method (Look, Test, Confirm, Exploit), players learn to turn opinions into facts, test an opponent with the right ball, and build a simple three-line game plan they can remember under pressure.

Nine stages, every exercise ready to run on court. Built for coaches, players and parents. Find the Hole is available on the 22nd of October. Stop guessing, start finding.

BRINGING SYSTEM-9 ONLINE TO YOU

Request a bespoke 1-3 hour video on any area of coaching you want to improve.

Every coach has areas they feel less sure about. Maybe it’s coaching the 4-10 age group, building rally tolerance, handling mixed-ability groups, or planning a full season. Generic courses rarely cover the exact thing you need.

So don’t settle for generic.

Tell us what you want to learn, and we’ll create a video just for you.
