How to Warm Up Before Swimming: The Best Pre-Swim Warm-Up Routine
/Ever jump into a swim set and feel stiff, slow, or out of sync?
I’ve coached a lot of swimmers who struggle through the first few hundred yards of practice. They’re not out of shape — they’re just not prepared. And more often than not, the issue isn’t the workout.
It’s the warm-up.
Most swimmers don’t give warm-ups the attention they deserve — and that’s a missed opportunity. A proper warm-up before swimming does more than “get you loose.” It prepares your body, your timing, and your technique so you can start swimming well from your very first lap.
Let’s break down what an effective swimming warm-up looks like — and how to use it to improve performance, reduce injury risk, and feel better in the water.
What Is the Best Warm-Up Before Swimming?
If you’ve ever asked yourself “what’s the best warm up before swimming?” — the answer is simple:
A proper swimming warm-up should:
Increase body temperature
Activate key muscle groups
Reinforce stroke mechanics
Prepare your nervous system
The goal isn’t just to loosen up. It’s to swim well from the start — not spend half your session getting there.
Why Static Stretching Before Swimming Can Hurt Performance
It’s still common to see swimmers do a few toe touches or hold long stretches before diving in. But here’s the problem.
Static stretching before swimming can:
Reduce muscle power and coordination
Decrease force production for up to two hours
Lower your core temperature
That’s exactly the opposite of what you want before a hard set or race.
That “stretch-and-go” approach might feel productive, but it doesn’t hold up against current sports science—or what I’ve seen on deck over the years.
In this video, I break down the six core elements of an effective warm-up that prepares your muscles, joints, and mind to train or race at your best.
Why Dynamic Warm-Ups Are Better Before Swimming
Before swimming, your warm-up should be dynamic—not static.
A dynamic warm-up uses controlled, movement-based exercises to:
Raise your body temperature
Improve mobility through swim-specific ranges
Activate shoulders, hips, and core
Prepare your timing and coordination
In simple terms, it helps you swim better, sooner.
If you care about performance, injury prevention, or just feeling strong in the water, this should be non-negotiable.
One of the Best Dynamic Warm-Up Exercises for Swimmers
If you’re looking for a simple way to warm up before swimming, skipping (jump rope) is one of the most effective options.
I’ve used it with swimmers who struggle to get loose early in practice, and within a minute or two you can see the difference. It raises body temperature quickly, sharpens coordination, and gets your timing in sync before you even hit the water.

5 Key Benefits of a Dynamic Swimming Warm-Up
1. Raises Core Body Temperature
Warmer muscles move better and are less prone to strain.
2. Activates Key Muscle Groups
Especially shoulders, hips, and core—the foundation of all four strokes.
3. Improves Stroke Mechanics
Dynamic movement reinforces the rhythm and positions you need in the water.
4. Increases Heart Rate and Blood Flow
Your body is ready for effort before the main set begins.
5. Boosts Focus and Coordination
A good warm-up prepares your brain just as much as your body.
Should You Stretch Before Swimming?
This is one of the most common questions swimmers ask.
Short answer: yes—but not the way most people think.
Static stretching → best after swimming
Dynamic movement → best before swimming
Static stretching before swimming can reduce power and coordination. Instead, focus on movement-based warm-ups that mimic your stroke and prepare your body for real swimming.
Example: 5-Minute Shoulder Warm-Up for Swimmers (On Deck)
Swimmers here’s a 5 minute shoulder warm up you can do on deck before your next swim to improve shoulder healthy and technique. Grab a band and find a bench or bleacher. Prone Scapular Retraction aka move your shoulder blade to improve the rhythm between your arm and shoulder blade 1 set of 20 reps Face Pulls - now load that rhythm,
I’ve used this exact sequence with swimmers who felt tight in the first 300–500 yards of practice.
The goal here isn’t fatigue — it’s activation, rhythm, and getting the shoulders working the way they should before you start pulling water.
Grab a light resistance band and a bench or bleacher.
Prone Scapular Retractions
1 set of 20 reps
Lay face-down on a bench with arms extended. Gently pull your shoulder blades together, then release with control.
This is where good strokes start—if your scapula doesn’t move well, your shoulder ends up doing too much work.
Face Pulls (Band)
1 set of 20 reps
Pull the band toward your face with elbows high and wide. Focus on external rotation at the end.
You’re balancing all the internal rotation from your catch—this is key for shoulder health over a long season.
Prone Trap Raises (Y Raises)
1 set of 20 reps
From the same prone position, raise your arms into a “Y” overhead with thumbs up.
This helps you find a strong overhead position and teaches your shoulder blades to upwardly rotate before your arm moves—exactly what you need in freestyle and backstroke.
Catch Patterning (Band or Bench)
1 set of 20 reps
Use a band or mimic the motion on a bench. Move through the “power diamond” catch position slowly and with control.
Think quality over speed—this is about reminding your body how a clean catch should feel before you get in the water.
If you have access to a Vasa Trainer, this becomes even more effective by directly connecting dryland work to your stroke.
Simple Pre-Swimming Warm-Up Routine (Quick Version)
If you’re short on time, use this structure:
On Deck (3–5 minutes)
Arm circles
Band pull-aparts
Shoulder activation drills
In Water (5–10 minutes)
200 easy swim
4×50 drill/swim
4×25 build
This is a simple, effective swimming warm-up routine you can use before any session.
When to Use This Warm-Up
Before pool workouts or swim meets
After travel or rest days when you feel stiff
Before open water swims, especially in cold conditions
Even 3–5 minutes makes a difference—but consistency is what drives results.
Warm-Up First, Stretch Later
Dynamic movements before swimming. Static stretching after.
Save longer holds and deeper mobility work for after your session, when your body is already warm and ready to adapt.
FAQs About Warming Up Before Swimming
-
Yes. A proper warm-up improves performance, reduces injury risk, and helps you feel better in the water.
-
Typically 5–15 minutes depending on your training session and experience level.
-
A combination of dynamic dryland exercises and easy swimming with drills.
-
It’s not ideal before training. Save static stretching for after your swim.
