There is a version of the indoor session that almost everybody has had. You book an hour, you warm up for four minutes, you pull the 7 iron because it is the club you like, and you hit it at the same target until something starts to hurt. Somewhere around ball 90 you switch to the driver, hit fifteen, get one that flies, and leave on that one.
The session felt good. By the end of it you were striking the 7 iron better than at the start. That improvement is real, and it is also the problem, because the thing that made it feel good is the same thing that stops it lasting until Saturday.
This is one of the best documented findings in motor learning and one of the least applied in golf. Practice conditions that produce the best performance during a session are frequently not the ones that produce the best learning afterwards. Repeating a shot lets you make small corrections against a fresh memory of the last one, which flatters your strike inside the session and leaves you with very little you can call on when the next shot is a different club at a different number with a different lie.
The order matters more than the content
The mechanism has a name. Contextual interference is what you get when practice makes you keep switching tasks instead of repeating one, and the effect of adding it is consistent enough to plan around. Blocked practice, meaning the same shot over and over, wins during acquisition. Random practice, meaning a different shot every time, wins on the retention and transfer tests that happen days later.
The interesting finding for a practice plan is that neither extreme is the best answer. Porter and Magill tested a third schedule that systematically increased contextual interference across the session, starting blocked, moving to serial, then finishing random, and compared it against traditional blocked and random schedules on a golf putting task. The increasing schedule produced the best retention performance of the three, and beat the random schedule on transfer as well.
That is the whole shape of a good practice hour, stated in one sentence by a study from 2010. Start by repeating. Then stop repeating. Then stop knowing what is coming next.
It is worth stating the size of the effect honestly rather than overselling it, because the plan below is built to respect the caveat. A 2024 systematic review and meta-analysis of 54 studies and 2,068 participants found that high contextual interference had a medium beneficial effect on retention overall, with a pooled effect around 0.63. The same paper reports that the effect was large in laboratory settings and close to negligible in applied ones, and negligible in young participants. In other words, the direction of the finding is well supported, and anyone promising you that random practice is a shortcut is going past what the evidence says.
The sensible response to that is not to ignore the finding. It is to ramp rather than to leap, and to give less experienced golfers more repetition before the interference starts, which is exactly what the planner does.
Session planner
Build the hour before you book it
Four answers, and the planner returns a timed plan for one bay session: what to hit, in what order, how many shots, and the one thing worth writing down in each block. Nothing is sent anywhere, and the reasoning behind the shape of the plan is set out below with the studies it comes from.
Reliable contact most of the time. Variety is where the gain is.
No round booked this week. Practice that feels worse now and holds up later.
60 minutes on approach play, in 4 working blocks after the warm-up, weighted toward repetition early and interference late.
- 9 min
Warm up
about 10 shots
Get the body moving and the strike settled before anything counts. None of these shots are data.
- Start with the shortest club you plan to use and make half swings until the contact sounds the same twice in a row.
- Work up through three or four clubs, a handful of shots each, without changing anything about your technique.
- Turn the screen away or ignore it. Numbers from a cold golfer are noise, and they set the mood for the hour.
- 14 min
Calibrate: one club, one number
about 31 shots
Blocked repetition with a single iron so you know what today's version of it carries.
- Pick one iron you use often and hit it to the same number every shot.
- Record carry, not total. Rollout belongs to the ground, not to your swing.
- Discard your first two and your worst one before you judge the average.
- 16 min
Vary: three clubs, one target
about 24 shots
Serial practice across the middle of the bag, where most approach shots are actually hit from.
- Choose three clubs that sit next to each other and rotate through them in order, one shot each.
- Keep one target for all three so you can see which club stops nearest.
- Do not correct anything mid-rotation. Note it and keep the order.
- 12 min
Pressure: random yardage
about 12 shots
High interference. You never hit the same shot twice, which is what the course does to you.
- Before each shot, generate a yardage between 100 and 190. Any random source will do.
- Choose the club yourself, and commit before you see anything on the screen.
- Score it: inside 30 feet is a point, on the green is half, missing it is nothing.
You have no round this week, so a bad score here costs you nothing. Set the target high enough that you fail sometimes.
- 9 min
Transfer: play the approach shots
about 6 shots
Put the skill in a hole with a number and a consequence attached.
- Play consecutive par 4s from the fairway, one ball, taking the yardage the hole gives you.
- Play the miss. If you are short-sided, that is now the shot you have.
- No re-hits and no second opinions about the club.
Short on purpose. When you are building something, playing holes is the test, not the training.
What each block is for
Five blocks, and each one has a different job. The failure mode of most practice is doing block two for the entire hour.
The warm-up, which is deliberately unmeasured
The first ten or fifteen shots of any session are not data and should not be treated as data. A cold golfer produces a strike pattern that has nothing to do with their swing, and looking at those numbers sets the tone for the next hour in the worst way: you see a bad figure, you go looking for a fix, and you spend the session solving a problem that existed only because your shoulders had not moved yet.
Turn the screen away. Short club, half swings, work up. You are looking for the sound of two clean strikes in a row, not a number.
Calibration, where repetition earns its place
Blocked practice is not a mistake, it is a stage. There is one thing it is genuinely best at, which is telling you what a club does today. If you want a carry number you can trust, you get it by hitting the same club at the same target enough times to average it, and that is a blocked block by definition.
This is also the only part of the session where staring at every number is the right call. If you want the full method for turning those numbers into something useful, the club gapping chart guide covers how many shots per club, which ones to discard, and what to do with the gaps you find.
Variation, where the repeating stops
Serial practice is the middle setting: you still know what is coming, but it is never the same as the last one. Three clubs in a fixed rotation, or one wedge at three swing lengths, or the same club at three different targets.
This block is where most golfers discover that the club they had grooved five minutes earlier does not survive being interrupted. That discovery is the point. A swing that only works in a block of twelve is not a swing you own yet, and finding that out on a Tuesday is much cheaper than finding it out on the first tee.
Pressure, where the shot is unknown and the score is real
Random practice with a score attached is the closest an indoor bay gets to golf. A different yardage every shot, chosen before you step in, with points that you write down and a target you sometimes fail to hit.
Two rules make this block work. First, no repeats, even when you miss badly, because the urge to immediately hit that shot again is exactly the urge the block exists to break. Second, the score has to be written down and kept. A game you can lose is a different activity from hitting balls, and the difference is measurable in how your heart rate behaves on the ninth one.
Transfer, where you play holes
One ball, real holes, no reloads. The tee shot decides the second shot, and a bad one leaves you with the awkward number you would have on a course.
This block is short when you are building something and long when you are playing on Saturday, which is the one difference the planner makes between its two modes. Rehearsing the thing you are about to do is a good use of two days before a round and a poor use of the off season.
Where to look, and how often
A launch monitor is the reason indoor practice works and the reason a lot of indoor practice does not. The screen supplies a number after every single shot, which is far more feedback than golf gives you and more than learning wants.
The 2024 systematic review of 52 randomised controlled trials on motor learning in golf covers this under augmented feedback, and the pattern is that reduced feedback schedules sometimes outperform continuous feedback on retention tests, particularly where knowledge of results is withheld for some trials. The reasoning is straightforward once you see it: a golfer who gets a number after every shot stops estimating for themselves, and estimating is the skill the course requires.
The same review reached a firmer conclusion about attention. An external focus, meaning attention on the target or the ball flight or the point where the club meets the ground, facilitated both performance and learning across putting, chipping, and full swing tasks. An internal focus, meaning attention on your own body parts, did worse. If you take one free thing from this page, take that one. Every block in the planner ships with an external cue, and none of them mention your wrists.
If the numbers themselves are the confusing part, our explainer on what the launch monitor figures actually mean goes through smash factor, spin, launch angle, and which ones you can safely ignore.
How many shots an hour is worth
The planner puts a shot count on every block, and the totals surprise people. A structured hour lands somewhere around 80 to 100 shots. The default unstructured hour is nearer 180.
The arithmetic is worth doing. One hundred and eighty balls in sixty minutes is a shot every twenty seconds, including the time it takes to rake another one over. There is no version of that where you picked a target, went through a routine, watched the flight, and thought about what happened. It is a physical activity that resembles practice, and it will make you better at hitting balls quickly.
This is where an auto-tee bay is a double edged thing. Not having to bend down for every ball is genuinely good for your back and genuinely bad for your pacing, because the friction that used to slow you down is gone. Put the pacing back in deliberately. The routine between shots is not dead time, it is the part you are actually trying to train.
What a bay cannot teach you
Indoor practice is very good at some things and unable to do others, and a plan that pretends otherwise will send you to the first tee with a false picture of your own game.
- Putting.A simulator bay is a full swing room. Shot Scope's tracked data has a 5 handicap going 16.7 holes between three-putts against 9.7 for a 15 handicap and 7.6 for a 25, and the cause they identify is distance control rather than aim. That is a strokes-per-round difference you cannot fix indoors.
- Lies. Every shot indoors is off a perfect surface. A ball sitting down in rough behaves differently and you have to learn that outdoors.
- Wind and slope. A flat mat and a still room remove two of the variables that make club selection hard.
- Consequence. This one you can partly fake, which is the entire purpose of the pressure and transfer blocks, but a scored game in a bay is not a medal on a Sunday and nobody should pretend it is.
What indoors is unbeatable at is measured, repeatable, weatherproof full-swing work with your own ball, which is most of what a golfer needs and almost none of what a driving range bucket provides. We wrote a longer comparison of simulators and driving ranges that goes through where each one genuinely wins.
Keep a log, or the sessions do not compound
Every block in the planner names one thing to write down. That is not decoration. Practice without a record is a series of unrelated hours, and the only evidence you have that it is working is how you feel, which is the least reliable instrument in the bag.
A usable log is four lines long: the date, the carry number for the club you calibrated, your score out of nine in the pressure game, and one sentence about what actually happened. Six weeks of that tells you whether the thing you have been working on is moving. It also tells you the more uncomfortable thing, which is when a swing change has been costing you for a month and you had not noticed because the individual sessions all felt fine.
The scoring games are the part worth protecting. A carry average creeping up is pleasant and does not necessarily mean anything. A pressure score going from four out of nine to six out of nine means you can do a thing under a small amount of stress that you previously could not, and that is what a lower score is made of.
How often to do this
Two sessions a week is the level where most amateurs see something change, and the second session matters more than the length of the first. Retention is a function of how often you come back, which is why an hour on Tuesday and an hour on Friday does more than a single two hour block on Saturday.
If you can only manage one, make it the one before you play, and use the round-prep setting in the planner so most of it is spent playing shots rather than drilling them. If you can manage three, alternate the focus rather than repeating it: the whole point of the schedule is to stop your practice from becoming one long block.
Doing this on the Westside
A plan like this needs a bay you are not being timed out of, your own ball, and a room where a scored game does not require an audience. That is close to a description of why Framegolf is being built the way it is: four private member bays in Culver City, an auto-tee on every bay, and a lounge rather than a queue. Founding member access will begin at the end of August 2026, and public membership opens in September 2026.
If you are weighing the options first, the LA simulator cost guide has the real hourly rates across the city and the membership arithmetic, the complete guide to indoor golf in LA covers every venue type, and the neighborhoods hub has your actual drive time from where you live. If you are considering building a bay at home instead, start with the room size guide, because ceiling height settles that question before the budget does.
And for the parts of the game a bay cannot cover, the Westside practice guide has every public range, short course, and putting green on this side of the city. A practice week with both in it is better than either one twice.

Questions people ask
How should I structure a golf practice session?
Warm up without measuring anything, then work through three stages in order: repeat one shot until the strike settles, rotate between a few clubs or targets so you never repeat the same shot twice in a row, and finish with a scored game where every shot is different. If you have a round coming up, finish by playing actual holes with one ball. That order is not a matter of taste. It follows the contextual interference research, where a schedule that starts blocked, moves to serial, and ends random produced better retention and transfer than either pure blocked or pure random practice.
How long should an indoor golf practice session be?
Between 45 and 90 minutes is the useful range for most golfers, and 60 is the sweet spot. Below about 30 minutes there is not enough time left after a warm-up to build more than one thing. Above 90 minutes, quality falls off well before the clock runs out, and the last 40 balls of a two hour session tend to reinforce a tired swing rather than a good one. Two focused hours a week, split across two sessions, beats one long one.
How many balls should I hit in a practice session?
Fewer than you think. A structured hour comes out around 80 to 100 shots once you include a real pre-shot routine, a scored game, and time spent playing holes. A golfer who hits 200 balls in the same hour is hitting one every 18 seconds, which leaves no room to aim, no room to think, and no room to notice what happened. The shot count is a symptom rather than the problem: if it is high, the session had no structure.
Is blocked or random practice better for golf?
Both, in that order. Blocked practice, meaning the same shot repeated, produces better results during the session itself and worse results later. Random practice feels worse at the time and holds up better afterwards. The 2024 meta-analysis of 54 studies and 2,068 participants found a medium overall benefit for high interference on retention, with the honest caveat that the effect was much smaller in applied settings than in the laboratory. The practical answer is to ramp: start blocked to find your strike, then increase the interference through the session.
What should I think about while practising?
The target, the ball flight, or the point where the club meets the ground, rather than what your body is doing. The 2024 systematic review of 52 randomised golf trials concluded that an external focus of attention facilitates both performance and learning, and the finding held across putting, chipping, and the full swing. This is one of the better supported ideas in the whole field, and it costs nothing to apply. Every block in the planner above carries an external cue for that reason.
Should I look at the launch monitor numbers on every shot?
Not for the whole session. Continuous feedback improves how you perform while it is available and can leave you worse off once it is gone, which is why reduced feedback schedules sometimes beat continuous ones on retention tests. The practical version: read every number while you are calibrating a club, then cut back to roughly every third shot once you are into variable and pressure work. Guessing the carry before you look is a useful drill in itself, because on the course the guess is all you get.
Can you practise your short game in a simulator bay?
Partly, and it is worth being clear about which parts. Full and partial wedge shots work well indoors, because carry distance is exactly what a launch monitor measures and exactly what most golfers cannot tell you about their wedges. Putting and greenside chipping off real turf are a different matter, and no amount of indoor practice replaces them. Shot Scope's tracked data has a 15 handicap going about 9.7 holes between three-putts against 16.7 for a 5 handicap, so the putting green is a genuine place to spend time. It just is not a bay.
