Drills Index

Putting:

3-foot circle drill — lag putt from 30–50 feet, count how many finish within 3 feet of the hole. Primary lag distance diagnostic. → Putting → Lag Putting
Clock drill — balls at 12, 3, 6, 9 o'clock positions at 30 feet; exposes directional bias in distance control. → Putting → Lag Putting
String line drill — taut string from ball to hole reveals start line, face angle at address, and roll quality. → Putting → Putting Drills
Gate drill (short putts) — two tees flanking the putter head just ahead of the ball; distinguishes path errors from face angle errors. → Putting → Putting Drills
One-hand drill — lead hand only; exposes wrist breakdown and trains shoulder-driven pendulum. → Putting → Putting Drills
Pure roll drill — logo or line on ball confirms end-over-end roll vs. wobble. No equipment needed. → Putting → Putting Drills
100-putt test — 10 balls from 10 positions around hole from 3 feet; counts made out of 100. Most diagnostic short-putt test. Benchmark: 85/100 recreational. → Putting → Putting Drills
Alignment mirror — reveals eye position, putter face angle, and stroke path simultaneously. → Gear → Practice Technology → Other Training Aids
Ridge-from-below practice — find a hole above a slope; lag from below and count how many crest the ridge cleanly. → Putting → Lag Putting

Short game:

Towel drill — small towel under both arms; trains connection and prevents chicken wing through impact. → Short Game → Short Game Drills
Feet together drill — narrow stance for chips and pitches; exposes sway and lateral slide. → Short Game → Short Game Drills
Landing spot drill — towel on green at intended landing spot; trains carry/roll ratio targeting. → Short Game → Short Game Drills
Two-tee gate (chipping) — tees flanking swing path; forces on-path strike through impact. → Short Game → Short Game Drills
Bunker line drill — draw a line in sand; practice entering exactly on it without a ball. Most fundamental bunker drill. → Short Game → Short Game Drills
Circle drill (bunkers) — draw 6-inch circle around ball; splash out the entire circle. Trains entry zone and follow-through commitment. → Short Game → Short Game Drills
Bunker distance calibration — hit five shots each to 10, 20, and 30 feet; calibrate swing length and entry point combinations for each distance. → Bunker Play → Greenside Bunkers

Full swing:

9-to-3 drill — half-swing from 9 o'clock to 3 o'clock isolates impact mechanics. Most efficient swing learning drill. → Iron Ball Striking → Full Swing Drills
Slow-motion swing — 10–20% speed with position stops; connects sensation to position. → Iron Ball Striking → Full Swing Drills
Step-through drill — step trail foot forward after impact; forces weight transfer and hip clearance. → Iron Ball Striking → Full Swing Drills
Headcover under lead arm — headcover between upper arm and chest; trains connection through impact. → Iron Ball Striking → Full Swing Drills
Alignment stick swing plane — stick at shaft angle trains correct downswing plane and slot. → Iron Ball Striking → Full Swing Drills
Tee drill for driver attack angle — forward tee must be clipped after impact; confirms upward attack angle. → Iron Ball Striking → Full Swing Drills
Impact tape / foot spray — contact pattern on clubface reveals strike location. → Iron Ball Striking → Full Swing Drills
Wall/chair hip drill — trail hip against wall prevents early extension; trains rotational clearance. → Iron Ball Striking → Common Faults and Fixes
Lead foot pressure check (backswing) — flare the lead foot and make slow backswings keeping pressure under the instep; a lead knee that dives rolls the foot onto its inside edge. Proprioceptive, no camera needed. → Iron Ball Striking → Common Faults and Fixes
Head height line (face-on video) — mark a horizontal line at the top of the head at address, compare to the impact frame; at or above is fine, below is the fault. → Iron Ball Striking → Swing Sequence
Alignment sticks (setup) — two sticks on ground reveal aim errors and swing path. → Gear → Practice Technology → Other Training Aids

Key Numbers

These are the specific numbers that appear throughout the document, gathered in one place for quick lookup.

Putting:

Optimal putting pace: ball should carry 17 inches past the hole if it misses (Pelz) — keeps the ball online through the final break
Acceptable lag zone from 30 feet: ball within 3 feet of hole (circle); 8/10 from 30 feet, 6–7/10 from 40–50 feet
Short putt benchmark: 85/100 from 3 feet (recreational); 95+/100 (tour)
Putting stroke ratio: follow-through slightly longer than backswing (1:1 to 1:1.5)

Driver:

Optimal launch angle: 12–15 degrees
Optimal spin: 2,000–2,800 rpm (recreational swing speeds)
Tee height standard: equator of ball at top edge of face (half ball above)
Tee height high: three-quarters of ball above face (lower spin, higher launch)
Smash factor: below 1.40 = off-center strikes; 1.48+ = excellent (TrackMan benchmarks)
Weight distribution at address: 55% trail side (promotes upward attack angle)

Irons:

Attack angle: 3–5 degrees downward
Weight distribution at address: 50/50 mid-irons; 55% lead short irons and wedges
Impact weight: 70–80% on lead foot
Hip angle at impact: 30–45 degrees open to target

Bunkers:

Standard entry point: 1.5–2 inches behind ball
Long bunker shots / more spin: enter 1 inch behind
Standard bunker practice: 10 balls, count finishing within 6-foot circle

Course management:

Wind: every 10 mph headwind costs approximately 1 club of distance; downwind benefit is roughly half the headwind penalty
Elevation: every 10 feet of gain/loss = approximately 1 club of effective distance
Altitude: 8–10% more distance at 7,000 feet vs. sea level
Lightning: stop play when thunder is 30 seconds or less after lightning; wait 30 minutes after last thunder before resuming

Tempo:

Tour player backswing-to-downswing ratio: 3:1 (Novosel / Tour Tempo research)

Handicap:

WHS calculation: best 8 of last 20 differentials
Handicap index represents potential (good day score), not average — average score typically runs 3–5 strokes higher

Rules of Thumb

Practical heuristics that hold true across most situations for most players. Not laws — but reliable enough to use as a default before adjusting for specific conditions.

Club selection:

Take one more club than you think on approach shots. Most recreational players consistently underclub — the dominant error is short, not long, and most hazards are in front of greens.
When between two clubs, take the longer one and swing smoothly at 85%. A smooth long-club shot outperforms a forced short-club shot in distance control.
Driver distance × 28 = the total course yardage at which the course plays appropriately for your distance. Below that yardage, consider moving up a tee.
In wind, club up and swing easy — a smooth shot with more club resists wind far better than a hard shot with less. (For the specific yardage adjustments, see Key Numbers above.)

Putting:

Miss putts on the high side (above the hole). A ball that misses high has a chance of catching the break and dropping; a ball that misses low cannot fall in. "Never up, never in" applies to the low side — always.
On any putt from 25+ feet, the goal is two putts, not one. Speed control should consume 80% of your mental energy; read the general quadrant and commit to pace.
The ideal dying pace leaves the ball 17 inches past the hole if it misses — fast enough to hold the line through the break, slow enough that it wouldn't travel far past (Pelz research).
Grain grows toward the setting sun on Bermuda grass greens — a reliable shortcut when reading grain direction in the afternoon.

Course management:

Miss the green on the side that leaves the easiest chip — not the side nearest the flag. Identify the safe miss before selecting the target.
Always leave the ball below the hole. An uphill 20-footer is significantly easier than a downhill 10-footer. Where the slope allows, favor the low side on approach.
The chip-out is not the coward's play — it is the correct play when all forward options carry disproportionate risk. A bogey from the fairway beats a double from the trees.
Never compound a mistake. After a bad shot, the next shot's only goal is to get back into a position from which a good shot is possible. Don't introduce a second risk to rescue the first one.
The most expensive shot is the one after a bad lie played aggressively. An unforced bogey costs one shot; an aggressive recovery that fails costs two or three.
Aim at the fat part of the green, not the flag, unless the flag is easily accessible. The pin is a trap on tight or tucked positions — the center of the green is always safe.
When in doubt about a carry over water or a forced carry: if the carry is at the edge of your comfortable range, lay up. The penalty for being one yard short is the same as thirty yards short.

On the tee:

The driver is the last club a beginner should master, not the first. Mid-irons are the learning clubs; driver technique follows.
Tee height matters: for irons on par 3s, tee the ball barely above the ground — the same as a fairway lie. A high tee with an iron produces thin contact.
If a tee shot may be lost or out of bounds, hit a provisional before searching. Always. It costs nothing if the original is found and saves a walk back to the tee if it isn't.

Equipment:

Regrip annually for players with 20+ rounds per year; every 6 months for high-frequency players. A worn grip is the most under-addressed equipment issue in recreational golf.
Replace primary wedges every 75–100 rounds. Test with the fingernail: drag it across the grooves — sharp ones catch, worn ones slide.
A properly fitted set of mid-range clubs outperforms an unfitted set of premium clubs for most recreational players. Fit first, then consider quality.
For iron shafts: driver swing speed under 85 mph → Regular flex; 85–95 mph → Stiff; 95+ mph → Extra Stiff. These are starting points for a fitting, not substitutes for one.
Free relief = 1 club-length; penalty relief = 2 club-lengths. Not always true under every rule, but a reliable default orientation for the most common situations.

Practice:

65% of all golf strokes occur within 100 yards of the hole (Pelz research). Practice allocation should reflect this — most players spend the majority of practice time on the range hitting full shots, which addresses a minority of actual scoring.
Block practice builds the pattern; random practice makes it transferable. Once a swing change is grooved in block practice, shift to random practice to make it stick under course conditions.
When fatigue brings the old miss back, the focused practice is over. Tired reps of a new move revert to the old pattern and groove the fault — stop the focused work or switch to slow rehearsal rather than emptying the bucket.
The 9-to-3 drill (half swing) is the most efficient drill for diagnosing and correcting impact conditions. When something is wrong, start there before making full swing changes.

Safety and rules:

30-30 lightning rule: if thunder follows lightning by 30 seconds or less, seek shelter immediately and wait 30 minutes after the last thunder before resuming.
3-minute ball search from when the search begins (not when you arrive at the area). Reduced from 5 minutes in 2019.
Never retrieve a ball within 10 feet of a water's edge in alligator country. The ball is not worth it.

Common Faults Quick Reference

Fault	Primary cause	Quick fix
Slice	Out-to-in path, open face relative to path	Fix transition (lower body first); check grip strength
Hook	In-to-out path, closed face relative to path	Check grip (weaken if too strong); fix path if too far inside
Pull	Out-to-in path, square face	Fix transition and casting; same root as slice
Push	In-to-out path, open face; or blocked release	Check hip clearance; allow forearm rotation through impact
Fat shot	Low point too far back; weight hanging on trail side	Fix weight transfer and hip rotation; check for early extension
Thin shot	Standing up through impact (early extension); low point behind ball	Maintain spine angle; wall/chair drill
Chicken wing	Blocked release; steering the shot	Allow forearm rotation through impact; headcover drill
Casting	Shoulders start downswing before hips	Lower body initiates transition; feel lead arm pull rope downward
Lead knee collapse	Lead knee dives in on backswing; pelvis, torso, and head drop with it	Hold knee flex and height; watch for the lead foot rolling onto its inside edge
Early extension	Hips thrust toward ball instead of rotating	Wall/chair drill; hips rotate, don't slide
Hip stall	Hips stop rotating through impact; hands flip to compensate	Rotate to a full finish, not to the ball
Reverse pivot	Weight stays lead-side on backswing, moves trail-side on downswing	Feel weight load into trail heel on backswing; let head move slightly right
Topped shot	Club rises before impact; early extension or weight back	Maintain posture; 9-to-3 drill
Shank	Hosel contact; club path too far inside-out or standing too close	Check distance from ball at address; path drills

Rules Quick Reference

Penalty areas (water hazards):

Stakes	Options	Penalty
Red (lateral)	1. Stroke and distance (re-hit from original spot) 2. Lateral drop — within 2 club-lengths of where ball crossed margin, no closer to hole	1 stroke
Yellow (regular)	1. Stroke and distance 2. Back-on-the-line drop (as far back as desired on the line from hole through crossing point) 3. Play it as it lies if findable and playable	1 stroke

Unplayable lie (anywhere except penalty area; player's call):

Option	Penalty
Stroke and distance — re-hit from original spot	1 stroke
Two club-lengths lateral — drop within 2 club-lengths, no closer to hole	1 stroke
Back on the line — drop behind the ball, as far back as desired on the line to the hole	1 stroke

Out of bounds / lost ball:

Stroke and distance only — re-hit from original spot, +1 stroke
Hit a provisional before searching to save time — provisional is abandoned if original found in bounds

Free relief (no penalty):

Cart path / immovable obstruction → nearest point of complete relief + 1 club-length, no closer to hole
Embedded ball in general area → lift, clean, drop within 1 club-length of reference point
Ground under repair / abnormal conditions → same as cart path

Ball moved by an animal:

Replace ball as near as possible to original position — no penalty

Key reference point for all penalty relief: where the ball last crossed the margin, not where it came to rest inside the area.

Full rules detail: → Rules of Golf

Common On-Course Situations — Quick Decisions

For the situations that come up every round and require an immediate answer:

Ball in water (red stakes): drop within 2 club-lengths of where ball crossed margin, no closer to hole. +1 stroke. Don't go back to the tee unless stroke-and-distance is the only option.

Ball in water (yellow stakes): same options as red, plus back-on-the-line (drop on the line from hole through crossing point, as far back as you like). +1 stroke.

Can't find the ball: you have 3 minutes from when you start searching. After that, stroke and distance. If you hadn't hit a provisional — go back and re-hit. +1 stroke. Use the local drop rule if the course has one.

Ball in trees/unplayable: declare it unplayable. Three options: stroke and distance, 2 club-lengths lateral, or back on the line. All cost +1 stroke. You cannot declare a ball in a penalty area unplayable — penalty area rules apply.

Ball on a cart path: free relief. Find the nearest point of complete relief — where the path doesn't interfere with your stance or swing — and drop within 1 club-length of that point, no closer to the hole. No penalty.

Ball embedded in the fairway: free relief. Lift, clean, drop within 1 club-length of the reference point, no closer to the hole. No penalty. (Does not apply in bunkers without a local rule.)

Accidentally move your ball on the green: replace it. No penalty — since 2019, accidental movement on the putting green incurs no penalty.

Ball moved by wind on the green after address: replace it at the original position if it moved after you began taking your stance. No penalty.

Wrong ball played: in stroke play, you must correct the mistake before playing from the next teeing area. Return to where you played the wrong ball, play the correct one. +2 strokes. If not corrected in time: disqualified.

Flagstick rules: you may leave the flag in when putting from anywhere on the course. No penalty for hitting it. Remove it or leave it — your choice.

Ball in Ground Under Repair (GUR): free relief. Nearest point of complete relief, drop within 1 club-length, no closer to the hole. No penalty. Applies if the ball is in GUR, or if your stance or swing area is in GUR — the ball doesn't have to be inside the marked boundary. Line of sight through GUR is not interference.

Ball on the real green when a temporary green is in use: free relief off the real green to the nearest point of complete relief, 1 club-length, no closer to the hole on the temp green. You cannot drop back onto the real green. No penalty.

Preferred lies / lift, clean, and place in effect: lift the ball, clean it, and place it (not drop) within the distance specified by the local rule — typically one scorecard-length or 6 inches. Ball must remain in the same general area; you cannot move it from rough to fairway unless the rule specifically permits. Does not apply in bunkers unless explicitly stated.

Hole closed during your round: treat it as par for handicap posting. Do not play it. Proceed to the next hole.

Pre-Round Checklist

[ ] Shoulder circles and arm swings
[ ] Progressive swings: wedge at 50%, wedge at 75%, irons, through to driver

On the practice green (after physical warm-up):

[ ] 2–3 long lag putts (30–50 feet) to calibrate the day's green speed
[ ] Several short putts (4–6 feet) from different angles to build confidence
[ ] A few chips from different lies to feel the turf conditions

On the first tee:

[ ] Agree on any casual round conventions with the group (gimmes, mulligans, preferred lies)
[ ] Confirm scoring format and side bets if any
[ ] Take one deep breath after address; begin the routine
