The Mirror Rule. Sixty seconds that decide whether this thing works.
Most bad reviews of rebound trainers describe the same failure. The fix is stance and aim, and it takes a minute to learn.
The rule
The ball returns as a mirror of your strike angle, measured from the base. Hit across the base, it swings away. Hit toward it, it comes back.
Same cord. Same ball. Different stance. Flip the diagram to see it.
Base out in front. You hit across it, the ball mirrors that angle and leaves.
Four things, in order.
Fill the base.
Water or sand. Full. A half-filled base walks.
Flat ground.
Concrete, asphalt, packed dirt, a patio floor. Grass slows the ball.
Run-out space in front.
The cord needs its full length ahead of you, plus a step.
Base at your feet.
Beside your front foot or just behind your heels. Never out ahead.
Seven days, ten minutes each.
First session: ten easy hits to calibrate, then count in a row. Stop at ten minutes.
Days 1–2 · Calibrate
Find the stance. Hit soft, flat, toward the base. Don't count yet.
Days 3–5 · Forehand only
Aim for ten in a row. When you get it twice, stop for the day.
Days 6–7 · Alternate
Forehand, backhand, forehand. Aim for twenty in a row.
If it keeps leaving.
It goes right (or left).
You're hitting across the base. Square up so your swing path points at it.
It goes high.
You're lifting. Hit flat and through, not up.
Cord slack or tangling.
The base is too close to your contact point. Step back half a pace.
