I’m Jenni Tristram. I work exclusively with elite ATP, WTA and top junior competitors.

My field is nervous system regulation. More than twenty years working with how people regulate, process and communicate under pressure, now applied to professional tennis.

The coaching, the physio work and the strength work all land on the same nervous system. How well they land depends on what state it's in.

Most of the time nobody knows what state that is. It gets inferred from body language or asked about directly, and a player under pressure is the least reliable witness to their own arousal. I measure it instead.

From there: what happens overnight and the morning of a match, the routine that gets you on court ready, the reset between points when the score turns, the two days after a loss, and underneath all of it, how you read what happens to you and what you believe you can do about it.

Measured, not guessed.
