Footwork Stances

Footwork stances define how the feet are positioned relative to the baseline and ball at the moment of contact. Each stance loads the body differently and produces different force vectors, rotation paths, and recovery options.

The notebook identifies three stances for forehand and one for backhand, with a unifying principle: the back leg is always the engine, and the front leg is always the "bridge" — absorbing and redirecting, never blocking.

The Three Stances

1. Open Stance (Forehand)

When to use: Ball arrives fast; no time to step through.

Foot position: Both feet parallel to baseline, wide stance. Body faces the net.

Force mechanics: - Push by Back Leg: primary force comes from the rear (right) leg driving outward-upward - Bridge by Straight Front Leg: front (left) leg stays extended but soft — like a bridge pier, not a locked joint. Transmits force without compressing the knee - Tension not overload: use quad and glute engagement to hold position; do NOT compress the knee joint with body weight

Hip/torso action: In modern tennis (Alcaraz, Kecmanović), even open stance includes torso rotation (see Forehand Technique Comparison - Rublev vs Alcaraz vs Sinner). The rotation happens upward, not flat — "back leg → front leg & upward."

Knee protection (52+ coaching note): Hips should be 5–10 cm lower than an upright standing position. Think "sit 5cm" without rounding the back. This protects the joint by putting load on the quad and glute, not the sụn (cartilage).

2. Square / Neutral Stance (Forehand)

When to use: Balanced rally ball; time to prepare; best for controlling direction.

Foot position: Feet roughly parallel to the net (perpendicular to baseline), roughly shoulder-width apart.

Force mechanics: - Back leg: deeply bent (Back Leg Knee Deep Bent) - Front leg: slightly bent (Front Leg Slightly Bent) - Weight transfer: back-to-front along the foot axis - Low center of gravity throughout

Why this works: The most stable stance. Allows both weight transfer and direction control. Front leg slightly bent means the knee never locks, preserving the kinetic chain (see Kinetic Chain).

3. Closed Stance (Backhand)

When to use: When time is available to fully prepare; maximum power situation.

Foot position: Front foot crosses ahead of body toward the ball (closed to net).

Force mechanics: - Back leg: deeply bent (Back Leg Deep Bent) — the primary motor - Front leg: straight bridge (Front Leg Straight Bridge) - Action: Both weight transfer AND rotation of the torso — back leg → front leg → upward. This is the most complete kinetic sequence; it activates Posterior Chain Activation fully.

Why closed generates most power: The body must uncoil through the full range. The sequential weight transfer (back-to-front) combines with torso rotation upward, amplifying the Power Wave Theory propagation.

The Three Universal Principles

Regardless of stance:

  1. Back leg is the engine: All three stances initiate force from the rear leg's deep knee bend. The posterior chain (calf, hamstring, glute, adductor) is the primary driver — visible as the red markings in the notebook sketches.

  2. Front leg is the bridge: Never lock the front knee straight. The "bridge" metaphor means: support without rigidity. The leg accepts load, transmits force, and protects the joint by staying slightly soft.

  3. Tension not overload ("always create a tension in the legs while no over-load on the knees"): Hold muscle tension in the quads and glutes continuously. Do not relax then suddenly absorb — the shock of sudden loading damages the knee. This is particularly critical for players over 50 in cold weather (Surrey context: cold = stiff joints).

The Split-Step Prerequisite

Before any stance is reached, the split-step determines everything:

  • Split-step as the opponent contacts the ball
  • Land with knees already bent (Federer model at 41 years old): never stand upright and then bend. The system should always be in "pre-tension" state.
  • Knee pointing outward along the toe line: prevents medial knee collapse ("no overload" in practice)

Drill: Hold the split-step position in front of a mirror for 10 seconds: wide feet, hips lowered, racket in front. You should feel quad and glute tension, zero knee pain.

Semi-Open Stance

A hybrid between Open and Square — the dominant stance in modern elite tennis (Alcaraz, Rublev, Fonseca). Described in the video analysis sections:

  • Front foot angled ~45° toward net, not square
  • Allows both forward weight transfer (like Square) and rotational freedom (like Open)
  • Transition: load in semi-open → finish in full open (hips rotate through, back foot lifts)

This is the "golden zone": time-efficient enough for fast rallies, loaded enough for power.

Common Errors

Error Consequence
Front knee locked/hyperextended Knee overload; wave transmission interrupted
Hips too high at contact Ground reaction force lost; must compensate with arm
Back foot planted after strike Weight transfer incomplete; arm-dominant shot
Feet flat (not on balls of feet) No split-step reactivity; late to all positions
