Learning better takes you further than simply playing more
You do not need to play more to improve. You need to learn to train smarter. Many players stay at the same level for years — not because they don't play enough, but because they don't develop with intention.
Tennis is the tool. Development is the goal.
Most players stay stuck at the same level too long. This is where the difference is made.
See below how this programme is structured in practice.

What Our Players Say
Read experiences from players and parents who train at 359.tennis.
This year I started tennis lessons at 359.tennis on Friday evenings from 20:00 to 21:00. Together with a large group of beginning adults, it's extra fun: there's a lot of variety in players, so you always find people you click with. The coach gives clear tips and I notice I'm progressing quickly. According to the instructor, I'll be able to play competition and tournaments this summer — I'm already looking forward to it.

Senior-beginner vrijdagavond
We play tennis together as a couple on Sunday mornings. It's become our quality time. The coach ensures we improve not just technically but also grow tactically as a doubles team.
Sandra & Willem Bakker
Dubbelpartners — zondagochtendgroep
For over 10 years, we've been taking tennis lessons at 359.tennis and playing Friday evening competition at TV De Kegel. We're a fun group of friends, levels 7 and 8, in the 50+ category. It's wonderful to be socially and athletically active together, but we also find it important to keep learning. And we still do: the coach always manages to teach us something new. The combination of lessons and competition makes it extra enjoyable — and truly keeps us together as a team.
