Good: weight stays over your feet through the finish. Losing it usually means the split-step landed early or late.

Shots 1, 2, 3 and 4

Balanced: weight stayed over your feet.

Shot to shot Low variance

Shots 1, 2, 3 and 4: avg 97/100. Balance about the same on every shot.

Good: feet about 2¼ shoulder widths apart as you start the swing.

Shots 1, 2 and 3

Wide base (0.41× your height). A solid platform to drive off.

Shot 4

Medium base (0.40× your height). Try this: land the split-step a little wider.

Good: a deep knee bend, near 90°, kept until you hit. Some straightening into the ball is leg drive.

Shot 1

Low and loaded (110° knee bend).

Shots 2, 3 and 4

Some load (117° knee bend). Try this: land the split-step earlier, knees already bending.

Most reliable on a feeding drill. In rallies, different balls make different shots.

Contact pointShown, not scored

Just in front

On the edge of Out in front

Contact slightly ahead of your body. Fine for defence; on attacking balls, meet it a little further forward.

Contact about 19 cm in front of your hips, the middle of 4 shots.

Weight transferShown, not scored

A little forward

Some weight into the shot, from a stable base.

Hips moved about 27 cm forward from the start of your swing until you recovered, the middle of 4 shots.

Front leg at contactShown, not scored

Firm

Front leg fairly straight at contact. Keep a little bend so you stay down through the ball.

Front knee at 161° at contact (180° is straight), the middle of 4 shots.

Strengths and next gains

From your tracked swings, not generic advice.

Working well

  • Balanced on shots 1, 2, 3 and 4: weight stayed over your feet.
  • Wide, athletic base on shots 1, 2 and 3.
  • Knees well bent and loaded on shot 1.
  • Head still through contact on shots 2, 3 and 4: little pull-back or lift.

Biggest opportunities

  • Load & hold is your lowest score this session (62/100). Try this: land the split-step earlier, knees already bending. Stay down until you've hit the ball.

Looking after your body

Patterns the video saw repeatedly this session, each with a fix and a stretch. Joint angles from video, not a medical diagnosis.

Wrist is bent out of line at contact2 of 4 shots

Measured: wrist 132° at contact (180° = hand in line with forearm).

See it on shots 1 and 2

A bent wrist at impact makes the forearm work hardest to hold the face steady. Repeated, that's a common cause of forearm and elbow soreness. (One camera sees the bend, not its direction.)

Try this: Firm the wrist just before contact so the hand stays in line with the forearm. The right grip size often helps more than trying to hold the wrist still.

Stretch for it Two-way wrist stretch. Arm out, palm up: pull the fingers back 30 s. Palm down: pull the hand toward you 30 s. Twice a day.

Your next session

  1. Your goal

    Load & hold: 62 → 80. That’s the step up to Strong.

  2. The drill

    Land the split-step earlier, knees already bending. Stay down until you've hit the ball.

  3. Film it the same way

    Same spot, same angle, same height entered, and a few more shots. Then the change between reports is you, not the camera.
