Two Corners
Why this drill
The machine's oscillator does what no partner can: perfect, tireless alternation. This is the drill that turns rallying into playing — hitting on the move, recovering through the middle, arriving balanced.
Setup
Machine on full oscillation, alternating feeds to both corners at an interval you can just barely handle cleanly. Start at the center hash.
The drill
Forehand crosscourt, recover past the center hash, backhand crosscourt, recover — in sets of ten balls. Every ball must land beyond the service line to count. Run six sets with thirty seconds' rest between them, and record your best set out of ten. When you can score eight or better on every set, tighten the interval.
One thought to take on court
Cross-step to sprint out, shuffle to recover — and never backpedal through the middle.
