Our Mission

What the balance bike is to cycling,
the roller is to tennis.

Whether at the club or at home, the starter roll is perfect for getting the youngest ones started. Many children only play tennis during lessons. We show parents how they can play with their kids themselves. Because the best moments are not created with the coach — but with you.

You've prepared everything. After 10 minutes, nobody wants to play anymore.

Court too big

Ball too fast

Frustration instead of joy

The problem is not your child.

With WHACK!, sessions become unforgettable moments.

Learning Together

First Rallies

Joy instead of frustration

YOUR CHILD WANTS MORE Tennis.

Coach Chris

From an experienced children's tennis teacher – for parents & coaches

For 25 years, I've been helping families teach their children tennis – and time and again, I've seen how frustrated parents are when tennis schools reject their children: "Too young. Come back in 3 years."

 

But these very first years are the most crucial!

 

During preschool age, children learn motor skills the fastest – and that's precisely where one should start.

 

That's why I developed the unique Roller methodology: Just as a balance bike makes cycling possible, Roller makes tennis possible.

 

As a certified coach and a father myself, I know: parents want the best for their child – but they need clear guidance, not a black box. With WHACK! Tennis, parents can give their children the best start themselves – without fear, without being overwhelmed, without detours.

Kids Tennis Training for Ages 3–6:
How to Start Tennis with Your Toddler

Can a 3 Year Old Start Learning Tennis?

Many parents wonder if 3 is too young to start tennis. It's not — but it has to be the right kind of tennis. Children's tennis training for toddlers isn't about hitting a ball over a net. It's about movement, coordination, and making the sport feel like play. The earlier kids start building ball sense, the easier every stage after becomes.

Tennis for 4-Year-Olds – The Right First Step

Teaching a 4 year old tennis works best when there's no pressure and no net yet. At this age, kids learning tennis need one thing above all: early wins. Rolling a ball in the right direction, controlling distance, moving their feet — these are the real building blocks of children's tennis at age 4. Skip this step and frustration follows fast.

How to Teach a 5 Year Old Tennis at Home

You don't need a tennis court to start kids tennis training with a 5 year old. A hallway, a garden, a living room — any flat surface works. The key is repetition through play, not instruction. Kids this age learn by doing, not by listening. Simple toddler tennis drills that feel like games are what actually stick.

Tennis for 6-Year-Olds – First Real Skills

By age 6, children are ready for their first structured tennis training. They can start connecting movement with a racket, learn basic direction control, and begin to understand the idea of a game. Tennis for 6 year olds is where fun turns into skill — if the foundation was built right in the years before.

What Kids Need Before They Can Hit a Tennis Ball

Most kids' tennis programs start too fast. Before a child can swing a racket, they need three things: the ability to move toward a ball, control its direction, and understand space. Kids learning tennis without these basics get overwhelmed quickly — and quit. Start with rolling. Hitting comes naturally after.

The Best Children's Tennis Training Tool for Ages 3–6

The WHACK! Rollo was built for exactly this stage. It gives toddlers and young kids a clear, playful task — roll the ball through, control the direction, repeat. No court needed. No coach needed. Just you, your child, and a system that actually works for kids tennis training from age 3 all the way to 6.

Start Tennis with Your Kids Today — No Experience Needed

You don't need to be a tennis player to start kids tennis training at home. The WHACK! system gives parents a clear roadmap: where to start, what to practice, and what comes next. Whether your child is 3, 4, 5, or 6 — there's a right entry point. And it always begins the same way: rolling before hitting.
