Indoor Swing Drills: All You Need Is a Mirror and Towel

Rain day. Snow day. Just-don't-feel-like-driving-to-the-range day. Whatever the reason, you're stuck at home and itching to work on your game. Good news: some of the most effective swing practice doesn't require a ball, a club, or even a lot of space. A full-length mirror and a towel are enough to make real improvements.

This isn't a consolation prize. Top teaching pros assign mirror work and towel drills to their best students because these exercises isolate the body movements that matter without the distraction of ball flight.

When you hit balls at the range, your brain focuses on the result — where the ball went. This sounds productive but it often isn't, because you'll unconsciously make compensations to get a decent result while ignoring the underlying mechanics.

Remove the ball and your brain shifts to the process. You feel positions. You see angles in the mirror. You can pause at any point in the swing and check. This is how lasting mechanical changes are built.

Stand facing a full-length mirror in your golf posture (no club needed). Check these five things:

Spend 2 minutes checking these positions daily. You're programming your body to return to a solid setup automatically.

This drill builds rotation awareness. Stand in your golf posture facing the mirror with arms crossed over your chest. Make a backswing turn, pause, and check three things: has your weight shifted to your trail foot? Has your lead shoulder turned under your chin? Are your hips turned roughly half as much as your shoulders?

Then turn through to your finish: weight on your lead foot, belt buckle facing the target, trail foot up on the toe. Hold the finish for three seconds.

Do 10 slow repetitions, checking the mirror at the top and at the finish each time. This builds the rotational range and sequencing that generate power.

This is one of the most popular drills in golf instruction and it works beautifully indoors.

Roll a hand towel into a loose cylinder. Hold one end in each hand as if it were a golf club, with your normal grip width. Make a swing. If you cast (release the wrists too early from the top), the towel will flop and feel limp. If you sequence properly — body leads, arms follow, hands release last — the towel will make a satisfying snap through the impact zone.

The towel gives you instant feedback on sequencing without any risk of putting a club through your ceiling fan. Start with half swings and gradually work up to full speed.

Research on motor learning consistently shows that slow practice builds skills faster than fast practice in the early stages of learning a movement. This applies perfectly to golf.

Make a complete swing at roughly 25% speed. Take a full 8-10 seconds from address to finish. Feel every position along the way: the takeaway, the top, the transition, impact, and follow-through. Pause at any position that feels unfamiliar or unstable.

This is harder than it sounds. Your body will want to speed up through the downswing because that's the habitual pattern. Resist it. The slow-motion swing teaches your body the correct path so that when you do swing at full speed, the positions are ingrained.

This one requires a club but no ball. Take your normal grip with any short iron, then bring your feet together so they're touching. Make easy half swings.

With your feet together, you can't use lower body sway or slide to compensate for poor mechanics. Your swing has to be balanced and centered. If you can make smooth contact with the ground (or a door mat) with your feet together, your balance and center of gravity are in good shape.

This is a great drill to do in a garage or any room with enough ceiling height for a half swing.

A complete indoor session takes 10 minutes:

• Minutes 1-2: Address position check in mirror (5 positions, hold each)
• Minutes 3-4: Turn and check drill (10 reps with pause at top and finish)
• Minutes 5-7: Towel drill (20 swings, focusing on the snap through impact)
• Minutes 7-9: Slow-motion swings (5 full swings at 25% speed)
• Minutes 9-10: Feet-together swings if space permits (10 easy half swings)

Do this daily and you'll notice a difference within two weeks. The positions will feel more natural. Your first few swings at the range will feel more connected. And your body will find the correct positions under pressure because you've rehearsed them hundreds of times.

Don't swing full speed with a real club in a small room. This is how ceilings, lamps, and relationships get damaged. If you're going to swing a club indoors, use a short iron and make half swings only, with plenty of clearance.

Don't obsess over one position. Work through the whole swing. Isolating one part without connecting it to the rest creates a disjointed motion.

Don't skip the mirror. Feel is unreliable, especially when making changes. What feels like a massive change is often barely visible. The mirror tells the truth.

Indoor swing practice isn't a substitute for hitting balls — it's a complement that many golfers skip to their detriment. Mirror work builds position awareness, the towel drill fixes sequencing, slow-motion swings encode motor patterns, and feet-together swings develop balance. Ten minutes a day with a mirror and a towel can produce more lasting swing improvement than you'd expect. No range required.
