How SeamSight trains.
Built by a tennis coach: practice has a job, and the job changes as a tournament gets close.
Strokes, tactics, points.
Foundational
Rally patterns that build the strokes, like forehand cross court for 90 seconds, then backhand cross court. The load steps up as you handle it.
Strategic
Ten-minute games with a tactic, like “cross court until a short ball, then change direction”. They give you ways to make an opponent uncomfortable.
Match Play
Points with a condition that forces a different situation, like finishing the point within five shots, or winning only on the other player’s errors.
The mix shifts as the date gets close.
Far out, most of the week goes to Foundational work and fitness. Closer in, more goes to Strategic games and Match Play. Strategic stays at about a third throughout, and every week keeps some match play, except the recovery week after a tournament.
Keep or change direction. Stand or run.
Every rally drill sits in one of four boxes: whether you send the ball back the way it came or change its direction, and whether you hit it standing or on the run. A good week covers all four, at the load you can handle.
Keep, standing
Cross court from the corner.
Change, standing
Take it down the line.
Keep, on the run
Pulled wide, back cross court.
Change, on the run
Pulled wide, then down the line.
The tools a Strategic game trains.
Each game works on one or more of these. Coaches choose how many minutes go to each.
Consistency
Direction
Depth
Height
Spin
Power
Court position
Time
Not just in or out.
Each level is a share of your shots in the drill, and each one sits inside the last: In, then Direction (the side the drill aims at), then Depth (past the service line), then Target (a 2 × 1 m box in the deep corner). Read with heart rate, they show whether your shots hold up when you’re tired.
