From a deep split stance, a tennis ball is held out to the side in front of the body with an outstretched arm and dropped straight down vertically. The other hand moves diagonally across the center of the body to the opposite side and catches the ball cross-body, ideally before it touches the ground. The task is then performed in the other direction. The legs maintain the lunge position while the arms and shoulder girdle carry out the diagonal catching movement. If more time is needed, let the ball bounce once on the ground and then catch it cross-body. After several repetitions, switch the front leg.
Training Goal
- Train diagonal movement patterns and crossing the center of the body.
- Improve eye-hand coordination through vertical dropping and diagonal catching.
- Connect the movements of the arms and shoulder girdle with a stable split stance.
- Develop balance and leg axis control in a deep position.
- Build both catching directions and split stances evenly.
Transfer to tennis
Diagonal movement patterns are an important part of many tennis movements. On the forehand and backhand, the arm and racket often move across the center of the body in combination with the rotation of the torso. Even when reaching for wide balls, leg position, trunk movement, and arm action must be coordinated with one another.
The exercise addresses part of these demands: the legs secure the deep split stance while the catching hand is guided diagonally to the opposite side of the body. This trains the coordinated interaction of a stable base with a body-crossing arm movement. The task generally prepares this movement principle; the transfer to the tennis stroke then follows in tennis-specific tasks.
Since the ball is released by hand, the focus is on movement timing, eye-hand coordination, and diagonal movement control.
Load Management
As a starting point, 2–3 rounds with 6–8 catches per split stance are suitable. The catching directions change within a round. Then switch the front leg.
Allow about 20–40 seconds of rest between rounds. Choose the depth of the position so that leg axis, balance, and diagonal catching movement remain controlled. If quality drops, make the task easier or end the round.
Coaching Keys
- Let the ball fall straight down without throwing it to the catching hand.
- Guide the other hand diagonally across the center of the body toward the ball.
- Track the ball with the eyes until it is caught.
- Load the front foot firmly and guide the knee toward the toes.
- Allow the shoulder girdle to move while keeping pelvis and legs controlled.
Progressive adaptation
Start with ground contact:
Let the ball bounce once and then catch it cross-body with the other hand. This creates extra time for the diagonal movement.
Catch before ground contact:
Move the catching hand diagonally toward the ball immediately as it is released. First choose a small lateral distance.
Increase lateral reach:
Gradually position the outstretched arm farther out to the side. This lengthens the diagonal path of the catching hand.
Vary the split stance:
Place both legs forward alternately. Deepen the position when execution is secure, or between catches, straighten up in a controlled way and take the position again.
Easier variation – catch after the bounce:
Let the ball drop straight down and bounce once on the ground. Then the other hand moves diagonally across the center of the body and catches the ball cross-body. The bounce on the ground creates extra time for the catching movement.
Harder variation – catch directly out of the air:
Let the ball drop straight down and catch it cross-body with the other hand before it touches the ground. The shorter available time increases the demands on movement timing and eye-hand coordination.
Possible corrections
The ball is thrown diagonally toward the catching hand:
Simplify the release: the hand opens, the ball falls straight down. The diagonally guided catching hand takes over the path to the ball.
The catching hand does not clearly cross the center of the body:
Hold the ball a little farther to the side and first trace the diagonal movement direction slowly with a handover of the ball. Then let it drop again and catch it.
The catching hand arrives too late:
Shorten the lateral distance or allow a bounce on the ground. Start the catching movement directly with the release.
The body tilts to the side while reaching across:
Choose a slightly wider split stance and reduce the reach. The arm moves toward the ball while the support position remains stable.
The front knee collapses inward:
Choose a less deep position and check the alignment of the knee over the foot.
