André Rennes — Driver Full Swing

A frame-by-frame biomechanical review of a filmed driver swing, his first face-on capture. It covers set-up, tempo, head and hip motion and sequencing, with benchmarks against average amateurs, low-handicap amateurs, the LPGA and the PGA Tour, and a comparison with his earlier reports. Includes a diagnosis, drills and a 4-week practice plan.

1 Executive summary

Bottom line: the set-up and the finish are strong. He has a wide, athletic stance, a healthy spine tilt away from the target at address, a one-piece takeaway, a lead leg that posts up at impact and a full, balanced finish facing the target.

The face-on view reveals the piece the down-the-line video couldn't show. From the top to impact his head travels about 5–7 inches toward the target, finishing almost over the ball. The hips move only about 3 inches, so the upper body outruns the lower body and the spine tilt he set at address (~12°) is gone by impact (~0°). Add the ~2:1 tempo, the same ratio as in his 6-iron and his October 7 driver, and it's a clear, coachable pattern.

Strength

Set-up & finish

Wide base, correct tilt at address, a posted lead leg at impact and a held, balanced finish.

Priority 1

Head stays behind the ball

Keep the head on or behind its address line through impact, and let the hips do the moving toward the target.

Priority 2

Tempo 2:1 → 3:1

A slower, complete backswing gives the lower body time to lead, which is what keeps the head back.

2 Timing & tempo — measured from the video

The video runs at 30 frames per second, so each time is accurate to about ±0.03 s. The top is set where the upper body's motion reaches its minimum.

The tour figures come from John Novosel's frame counts in Tour Tempo. The amateur and LPGA ranges are typical values from the same research and coaching literature, not one official table.

What it means: his total time is tour-like, but it's split the wrong way. The backswing is about 0.2 s shorter than a tour player's and the downswing is slightly slower. A rushed backswing leaves the body no time to sequence, so the upper body starts down first. That's the head move in section 4. This is the third report in a row at ~2:1 (6-iron, October 7 driver, now this), so it's a habit, not a one-off.

3 Swing sequence

Nine key positions, filmed face-on from an elevated phone. André is right-handed, so the target is to the right of the image. The top of the club leaves the frame at the top of the swing.

P-numbers follow the standard 10-position swing model. Impact is the frame where the clubhead blurs through the ball and the ball leaves the tee.

4 Position-by-position biomechanics

P1 — Address Good

  • A wide stance, wider than the shoulders, gives a stable base for a driver.
  • The spine tilts about 12° away from the target, with the head behind the belt buckle. That's the right driver set-up.
  • The ball sits about 2–3 inches inside the lead heel. It's close, but moving it 1–2 inches forward, opposite the heel, helps the upward strike.
  • Alignment sticks on the mat are a good habit, so keep them.

P2 — Takeaway Good

  • A wide, one-piece takeaway: arms, hands and club move away together, and the lead arm stays straight.
  • The lower body is quiet, and the head stays on its line.

P3 — Lead arm parallel Good width

  • The lead arm is long and the arc is wide.
  • The trail leg holds its flex, so the hips turn instead of sliding away from the target.

P4 — Top of backswing Short load

  • A good shoulder turn: the back faces the target and the lead shoulder works under the chin.
  • The head moves only about 1.5 inches to the trail side. Tour players commonly load 0–4 inches, so that's fine. The issue is what follows.
  • The lead knee moves in toward the trail foot. That's moderate and acceptable, but keep it pointing at the ball.
  • The club leaves the frame, so its length at the top can't be judged here.

P5 — Lead arm parallel (down) Key issue starts

  • The head is already ahead of its address line before the hands reach the trail hip. The upper body is starting the downswing.
  • In a tour sequence the hips lead and the head stays back. Here the order is reversed.

P6 — Delivery Upper body leads

  • The hands drop to the trail thigh with the arms close to the body.
  • The chest and head keep drifting toward the target, and the spine is close to vertical.

P7 — Impact Key issue

  • The head has moved about 5–7 inches toward the target from address and sits almost over the ball (see the overlay below).
  • The hips have moved only about 3 inches forward. Tour players move the hips about 4–6 inches while the head stays put, so here the head outruns the hips.
  • The result: the spine tilt goes from ~12° at address to ~0° at impact. Tour drivers increase their tilt, to roughly 25–35° away from the target.
  • On the plus side, the lead leg is posted straight and the trail heel releases. Those are good.

P8 — Release Full extension

  • Both arms extend toward the target after impact, with no chicken wing.
  • The trail knee drives toward the lead knee, showing full weight transfer.

P10 — Finish Excellent

  • Tall and balanced on the lead leg, with the belt facing the target, the club wrapped behind the head and the trail foot up on its toe.
  • He holds it, as in his 6-iron and his October 7 driver. That's a reliable strength.

Overlay — head at address, top and impact

Head position at address, top and impact

The white line marks the centre of the head at address. The gold line marks the ball. At the top the head is slightly behind the white line, a normal load. At impact it has moved most of the way to the gold line. The camera didn't move: the alignment stick and the fence stay in place. Distances are estimated from stance width with perspective correction, so treat them as ±1.5 inches.

6 Driver benchmarks — amateurs, LPGA, PGA

This video has no launch-monitor screen, so his numbers come from his October 7 driver session at Mariners Point.

Where it connects: with the head moving forward and the tilt lost, the low point of the swing moves toward the ball. That usually means a less upward strike, more spin and a face that's harder to square. On October 7 the drive curved 38 ft. Keeping the head back is the most direct way to turn his efficient 213-yd carry into straighter, longer drives.

7 Across his reports — one pattern, two views

ReportViewHead movement foundTempo
6-ironDown-the-line—~2:1
Driver, Mariners Point (Oct 7)Down-the-line~5 in down, ~2 in toward the ball~2:1
Driver, Crystal Springs (this)Face-on~5–7 in toward the target~2:1

The connection: the two driver views show the same move from different angles. In the downswing the head goes down, toward the ball and toward the target, so the upper body "covers" the ball instead of staying behind it. One cue fixes all three directions: keep the head where it started until the ball is gone.

8 Diagnosis

  1. The foundations are sound: stance, address tilt, takeaway, lead-leg post and finish are all at a good amateur standard or better.
  2. The upper body starts the downswing: the head is ahead of its address line by P5 and ends 5–7 inches forward at impact.
  3. The hips under-shift: they move only ~3 inches, so the spine tilt collapses from ~12° to ~0° instead of increasing.
  4. The tempo drives it: a 0.6-s backswing (~2:1) gives the lower body no time to lead the downswing.
  5. Ball position is a small extra: 2–3 inches back of the heel, which adds to a less upward strike.

Confidence: high on the head movement and the tempo, which are measured against the fixed alignment stick and fence. Moderate on the exact inches and tilt angles, since this is a single elevated phone view.

9 Fixes & drills (in priority order)

Priority 1 · Head

Phone line check, face-on

Film from this same spot. Put a vertical strip of tape on the phone screen at the target side of the face at address. Hit 5 drivers: the face must stay behind the tape until the ball is gone.

Objective feedback on the exact fault measured here.

Priority 1 · Head

Headcover outside the lead ear

A friend holds a headcover (or a club grip) just outside the lead ear at address. Make half-speed swings without touching it until after impact.

Teaches the feel of the head staying back while the body turns through.

Priority 1 · Tilt

"Bump and tilt" pump drill

Swing to the top. Bump the lead hip 3–4 inches toward the target while the trail shoulder goes down and the head stays back. Pump twice, then swing through.

Makes the hips lead and builds the tour impact tilt (25–35° away).

Priority 2 · Tempo

Tour Tempo 24/8 or 21/7

Rehearse to a 3:1 tempo track: three counts back, one through. Start with practice swings, then hit balls.

A slower, complete backswing gives the lower body time to start down first.

Priority 2 · Set-up

Tee at the lead heel

Use the perpendicular stick already on his mat as a marker, set level with the lead heel, and tee the ball on that line.

Encourages the upward strike: higher ball speed and less spin.

Keep

Hold-the-finish rule

Hold every swing in the finish for a three-count.

Protects his best asset while the downswing changes.
