Rooted in movement. Built for tennis.

Find your power.
Not a harder swing.

Your arm isn’t the whole story. Find the link leaking power in your stroke, then build a better connection from the ground to your racket.

For club players, NTRP 3.0–4.5. One link at a time.

The ChainSpark approach

The power starts beneath your feet.

Ground → body → racket. Connect the chain.

Our promise to players

Less noise. More connection.

Clear explanations, not quick-fix claims

Focused drills, not 20 random tips

Made for everyday club players

One framework. Every stroke.

Your stroke is a chain.
Let’s connect it.

Forehand, backhand, serve or volley: power travels through the same six links. We help you understand where the sequence breaks, so your next practice has a purpose.

The six-link chain

01 / FIND THE LEAK

A clearer picture of your stroke.

Film a stroke side-on and work through the free six-question Leak Test. Your Leak Card names the link to focus on, giving you a starting point instead of another guess.

Example Leak Card

“My forehand leaks at Link 3 — Hips.”

The Leak Test is part of our launch plan. Create an account to follow launch updates.

02 / WORK ON ONE LINK

A practice plan, not a tip spiral.

Link Fix drill packs give you a focused 30-day plan for your leaking link. Build the movement, take it to court, then film again to see what changed.

03 / KEEP THE CHAIN MOVING

Practice. Feedback. Repeat.

Chain Club brings the drill library, a monthly live lab and one video review per month together. Come with a question; leave with something specific to work on.

Real feedback for your own stroke.
