- A ball hopper + 60–90 balls. The highest-value purchase in tennis: it unlocks every solo drill in our library for the price of one lesson.
- Flat targets — throw-down lines, cones, or honestly a towel. Aimed practice beats volume practice; targets are how sessions get scores.
- A jump rope. The cheapest footwork coach ever made.
- A phone tripod or fence mount. Ten filmed serves tell you what no amount of feel can — see the Phone Check drill.
- Ball machines: a genuine upgrade if you'll use it weekly — portable spinner class (Slinger-style) for convenience, traditional oscillating machines (Lobster / Spinshot class) for programmable drilling. Be honest with yourself first: a wall is a free ball machine, and 25 of our drills run on it.
