Swimming Workout: Muscles Used, Benefits, Getting Started Tips

The Many Benefits of Swimming for Exercise and Health

Swimming is one of the best forms of exercise you can do. It works your entire body, improves cardiovascular fitness, builds strength and endurance, and has numerous other health benefits. Here's a look at why swimming can be an excellent part of your workout routine.

Swimming Provides a Full-Body Workout

Unlike some types of exercise that focus on specific muscle groups, swimming works your entire body all at once. Nearly all of your major muscle groups get activated while swimming. This includes the arms, back, chest, core, glutes and legs. Swimming engages all these muscle groups together in a smooth, flowing motion.

As you propel yourself through the water, you use your arms for stroking, your back and chest to control your body position, your core for balance and stability, and your legs for propulsive kicks. This total-body stimulation provides diverse fitness benefits in one workout.

It Improves Cardiovascular Fitness

Swimming requires endurance and sustained physical exertion. This makes it an excellent cardiovascular exercise. Research shows swimming can help lower blood pressure, reduce inflammation, improve cholesterol levels and boost heart health. The continuous movement involved in swimming makes your heart pump blood throughout your body to deliver oxygen to your working muscles.

Over time, the consistent aerobic stimulation of swimming can strengthen your heart, improve circulation and increase stamina. Swimming just 30-60 minutes 2-3 times per week has been shown to generate these cardiovascular perks.

Swimming Builds Muscle Strength

The resistance provided by the water makes swimming an ideal strength-building exercise too. When combined with sustained aerobic activity, research indicates swimming can help increase lean muscle mass. Although not as directly targeted as weight lifting, swimming engages all your major muscle groups and causes them to work against resistance.

This can strengthen and tone the muscles in your arms, shoulders, chest, back, glutes and legs. The more you swim, the greater potential for building endurance and power in the engaged muscle groups. Interval swimming and utilizing equipment like paddles or kickboards can further maximize muscular benefits.

It's an Efficient Calorie Burner

Swimming burns lots of calories, making it great for controlling weight. A 160-pound person can burn nearly 500 calories by swimming at a low to moderate pace for an hour. Faster swimming for the same duration can burn over 700 calories. This exceeds calorie expenditure for running, biking, or other mainstream cardio workouts.

The resistance of the water requires more energy expenditure for movement. You burn lots of calories while improving muscle tone and cardiovascular endurance. Swimming is also generally easier on joints than high-impact exercises like running. For these reasons, it can be an ideal part of a weight management regimen.

The Muscles Utilized When Swimming

Because swimming works your whole body simultaneously, it utilizes most of the major muscle groups. While techniques and strokes vary, the primary engaged muscles while swimming typically include:

Arms and Shoulders

Your upper body is constantly in motion while swimming. With every stroke, your arms pull your body through the water, generating propulsion. The arm and shoulder muscles recruited during the swimming motion include:

• Latissimus dorsi - broad back muscles
• Pectorals - chest muscles
• Deltoids - shoulder muscles
• Biceps - upper arm muscles
• Triceps - back of the upper arms
• Forearms and wrist - rotate and control hand/arm

These muscles provide powerful propulsion with each stroke and control the movements of your arms and shoulders throughout. Alternating strokes work the arms bilaterally for balanced strength building.

Core

While less directly involved in propulsion, the muscles of your core are constantly active during swimming. Core muscles engaged include:

• Rectus abdominis - central abdominal muscle
• Obliques - side abdominal muscles
• Transverse abdominis - deep core support
• Erector spinae - muscles along the spine

These core muscles stabilize your body position, regulate breathing patterns and enable balance while propelling yourself horizontally through the water.

Legs

Although arm stroking provides most forward propulsion, your legs also play an important role. Leg muscles activated while swimming include:

• Quadriceps - front of thighs
• Hamstrings - back of thighs
• Glutes - buttocks muscles
• Hip flexors - front hip muscles
• Calves - lower legs

Leg kicks provide additional forward thrust, help stabilize body position and contribute to sustained momentum. Alternating flutter, dolphin or frog kicks work the legs through their full range of motion for a great workout.

Back

Postural muscles of the back help control body alignment and stabilize your torso while swimming. Key back muscles engaged during swimming include:

• Trapezius - upper back around shoulders
• Rhomboids - middle back between shoulders
• Latissimus dorsi - broad lower back

These back muscles allow necessary shoulder mobility for comfortable swimming strokes while helping keep good spinal alignment and reduce strain.

How to Get Started With Swimming for Fitness

If you're new to swimming, it's easy to get started. Here are some tips for learning proper swimming technique and integrating it into your routine:

Take a Class or Get Lessons

Start by signing up for an adult swim class at your local pool. Having an instructor teach you proper form and technique can help you pick up swimming more quickly. They will cover basics like breath control, body position, stroke mechanics and turning. A few sessions of lessons can give you the foundation to start swimming laps on your own.

Master Basic Strokes

When first starting out, focus on proper form and coordination for core swimming strokes. The front crawl (freestyle) and backstroke are excellent starter strokes. As you improve, add breaststroke, butterfly and sidestroke. Mastering all the strokes will help you develop full swimming proficiency while working your muscles in diverse ways.

Invest in goggles, cap and swimsuit

Having the proper swim gear will make your time in the water more comfortable and enjoyable. Well-fitted goggles allow clear underwater vision, a swim cap keeps hair contained, and a swimsuit made from nylon/Lycra provides durability and flexibility. Your local swim shop can help find gear that's right for your needs.

Start Slow and Focus on Technique

As with any new exercise routine, gradually ease into swimming to allow your muscles to adjust. Start by swimming 10-15 minutes at an easy, restful pace. Concentrate on your body position and stroke mechanics first before trying to go farther or faster. Proper technique is crucial for efficiency and injury prevention.

Schedule Regular Swim Sessions

To progress in your swimming fitness, aim to work swimming into your weekly schedule 2-3 times. Consistent practice allows muscles adaptation and increased endurance over time. Even 30-45 minutes per session provides excellent cardiovascular benefits. Just remember to start slow and focus on proper technique above all else.

Improving Your Swimming Technique and Endurance

Once you've gotten comfortable with basic swimming, there are ways to take your workouts to the next level. Here are techniques to improve your efficiency and build swimming endurance:

Refine Your Stroke Technique

Proper stroke form helps you swim faster while expending less energy. Elements to focus on include:

• High elbow catch - keeps forearm aligned with body
• Early vertical forearm - enters water sooner
• Anchor point hand entry - keeps hand perpendicular
