Swimming is an incredible full-body workout that engages multiple muscle groups, burns calories, and boosts cardiovascular health, making it an effective activity for weight loss. Whether you’re looking to lose a few pounds or improve your overall fitness, swimming provides a low-impact yet powerful way to achieve your goals. It's a fun summertime activity that is refreshing and has many other health benefits. For those of us who struggle to work out in hot conditions, deal with aching joints, or have sustained injuries to our back, knees, or ankles, swimming is a great way to increase fitness levels.
Why Swimming Helps with Weight Loss
There is a common misconception that swimming is not effective for weight loss. Some even suggest that "you're better off walking around a pool than swimming in it" [1]. However, research paints a different picture. One study compared the effects of swimming and walking for weight loss, both performed at the same intensity and frequency (3 times per week). The swimming group lost an additional 2 pounds and 0.7 inches from their waistline compared to the walking group [2].
Here's a breakdown of why swimming is such an effective tool for shedding those extra pounds:
- Efficient Calorie Burning: Swimming is an efficient calorie-burning exercise. The calories burned during your swimming session depend on the intensity of your workout. If you're swimming intensely 4 times a week, you can expect to lose around 2-4 pounds a month [4]. If you're just starting out with swimming and are gradually increasing from low to high intensity, a moderate-intensity session for half an hour burns around 250 calories. If you do that 4 times a week, you can expect to lose roughly 1 pound a month [4]. It's also important to note that calorie burn varies from person to person. According to Harvard Health, the calories burned are influenced by your current weight and the intensity at which you swim [6].
- Full-Body Engagement: Swimming works nearly every major muscle group, from your core to your legs, arms, and back. Swimming is a full-body workout routine that activates different muscles in your body. Various strokes, such as the butterfly, breaststroke, and backstroke, target specific body parts. The butterfly and breaststroke target your chest, arms, and shoulders, while the backstroke targets your abs, back, and quads [4].
- Metabolic Boost: Swimming can increase your metabolic rate, helping you burn calories even after your workout. A higher metabolism means that you’ll have an increased energy level and burn more calories during periods of rest and activity.
- Joint-Friendly Exercise: Swimming is gentle on the joints, making it suitable for people with arthritis, joint pain, or those recovering from injury. Swimming is also much better for your joints compared to running or walking, reducing the likelihood of injury and increasing the probability of consistent exercise, which aids weight loss [1].
- Lean Muscle Development: Swimming builds lean muscle, which boosts your metabolism and helps your body burn calories more efficiently.
- Cardiovascular Health Improvement: Swimming is an excellent cardio workout, strengthening your heart and lungs. Breaststroke helps to strengthen the heart and lungs [9].
- Stress Reduction: Stress and poor sleep are linked to weight gain. Exercise releases endorphins, which improve mood. A 2014 pilot study involving people with dementia found that those who swam regularly in a 12-week period showed an improvement in mood. The study took place in Queensland, Australia. The participants had a median age of 88.4 years, and the cohort consisted of 10 women and one man. Exercise is a great way to relieve stress and anxiety. Aerobic exercise may elevate and stabilize mood and reduce tension overall. A 2014 study in rats found that swimming could help reduce stress-induced depression.
- Core Strength Enhancement: Your core muscles are constantly engaged during swimming, which helps with balance, stability, and overall strength.
- Adaptable Fitness Levels: Swimming can be tailored to any fitness level, allowing you to progress at your own pace.
- Enjoyable and Sustainable: Swimming is a fun and refreshing way to exercise, making it easier to stay consistent.
Getting Started with Swimming for Weight Loss
If you've never tried swimming for weight loss before, it might be worthwhile to gradually increase your intensity, starting with moderate intensity. You could even enlist the help of a swim coach to ensure your form is optimal.
Aim for 3-5 times per week, with each session lasting 30-60 minutes. To burn calories through swimming, both the duration and intensity of your swimming session matter. An hour of moderate-intensity swimming can burn approximately 500 calories [5]. Additionally, varying your swimming strokes can further increase calorie burn.

Here are some tips to maximize your weight loss efforts in the pool:
- Consistency is Key: The key to losing weight, regardless of the exercise, is consistency and maintaining a calorie deficit. For the best results, it’s important to stay consistent with your swimming routine. With a consistent water workout, you should begin seeing weight loss within 30 days.
- Vary Your Strokes: As with all workout routines, you'll want to switch up your swimming strokes to burn more calories and keep things interesting too. Plus, to ensure you're working your entire body, you need to engage every muscle group, which is quite easy to do with swimming by incorporating different swim strokes. For maximum calorie burn, ensure your workout includes kicking, pulling, and stroke work [10].
- Reduce Rest Periods: Another tip to burn more calories while swimming is to reduce rest periods during your session. Swimming for longer and resting less keeps your heart rate elevated and helps to burn more calories [5].
- Incorporate Training Aids and Weights: Another excellent way to burn more calories in the pool and keep things interesting is to incorporate training aids and weights. Using kickboards and pull buoys helps target specific areas of the body. You can also introduce resistance training into your swimming sessions by using aqua dumbbells, which can help you lose weight by increasing your resting metabolic rate, meaning your body burns more calories even at rest. It's also great for building muscle [8].
- Consider Consulting with Your Doctor First: It is important to have a doctor’s approval before beginning or resuming any exercise program.
- Start with Warming Up: The first part of any swimming workout is the warm-up. The warm-up will get your blood pumping and your muscles ready for action.
- Start Slow and Work Your Way Up:
- Use Pool Accessories Like Noodles and Floats:
- Join a Swim Group or Club: Join a swim group or club for motivation and camaraderie.
Swimming Strokes for Weight Loss
Swimming laps is a vigorous exercise that will increase your heart rate and breathing significantly. The stroke you do when swimming is an important part of losing weight. There are four types of popular swimming strokes that are beneficial for losing weight.
Here's a breakdown of some of the best swimming routines for weight loss:
Intensity is key: A high-intensity workout routine combines intense swimming with rest periods or recovery swims. Even though you might not swim as much in your session, it's great for those who need to fit a workout into their busy days. Plus, you'll burn a significant amount of calories [7]. You could even try high-intensity interval training (HIIT) to burn calories and fat. A swimming HIIT session means you're swimming short bursts at maximum effort, which can increase your overall fitness levels and burn more fat [8]. A simple way to do this is to swim at high intensity for 30 seconds and include a 15-30-second rest period before your next sprint. Aim for as many repetitions as you can manage, but try to hit double-digit figures [8].
The best strokes: For a total body workout, you'll want to incorporate different strokes into your swimming routine. Each stroke targets the body differently and can have significant benefits on posture, toning the body, and building muscle tone and strength.

- Butterfly: The butterfly stroke is the best swimming stroke for weight loss, though it's also the hardest to master. The average calories burned swimming the butterfly stroke is roughly 450 calories in a 30-minute swimming session. The butterfly stroke also increases your flexibility, tones your chest, stomach, and arms, and helps to build upper body strength [9].
- Freestyle: Freestyle is the fastest stroke and can help you burn roughly 300 calories in a 30-minute swimming session. Freestyle also helps to tone your stomach, bum, and shoulders. It's a great stroke to start with as you work your way towards a high-intensity session [9].
- Backstroke: Backstroke is one of the best swimming strokes to help improve posture, though it's not as effective at burning calories. On average, you can burn around 250 calories in a 30-minute swimming session. Backstroke helps to tone various parts of the body, including the stomach, legs, arms, and shoulders [9].
- Breaststroke: For a 30-minute swimming session, breaststroke will help you burn 200 calories but it's great for cardiovascular health, helping to strengthen the heart and lungs [9].
Beyond the Pool: A Holistic Approach to Weight Loss
Diet plays a more significant role in weight loss than physical activity. So, if you're eating poorly and swimming for weight loss, it won't make a huge difference. Instead, a combination of a balanced diet and regular exercise is the key to losing weight.
While swimming offers a range of health benefits from weight loss to muscle toning and even mental health benefits, it's definitely not for everyone. If you've tried swimming for weight loss and just don't enjoy it, or you're not seeing any weight loss results, there are other things you can try. There's a plethora of physical activities you can do to lose weight aside from swimming. At the end of the day, the goal is to find a form of exercise that you genuinely enjoy so that you stay consistent and incorporate it into your lifestyle.
Here are some additional strategies to support your weight loss journey:
- Healthy Balanced Diet: If you're trying to lose weight, the most crucial changes you can make are to your diet. Eating a healthy balanced diet consists of five food groups, which you should be eating every day. These include: Vegetables and legumes, Fruit, Lean meat, chicken, fish, eggs, tofu, nuts and seeds, Dairy products including milk, cheese, yogurt, or alternative dairy products, and Grains and cereals [11]. Incorporating fibre-rich foods into your diet is also beneficial for weight loss. Research suggests that eating 30 grams of fibre a day can aid in weight loss, improve the body's response to insulin, and decrease blood pressure [12].
- Other Forms of Physical Activity: You could try water aerobics, cardio activities like running, walking, going to the gym, strength training, or even going for a beach swim. The most important thing is to improve your fitness level and do it consistently.
- Holistic Weight Loss Programmes: If you've been struggling with weight loss for some time and feel like you've tried all the physical activities out there and changed your diet, but nothing seems to work, consider holistic programme designed for long-term and sustainable weight loss.
