Swimming is one of those sports that has it all: Take care of your joints, improve your heart, strengthen your muscles, and clear your mindFurthermore, you can adapt it to almost any age and fitness level. However, to see real results, it's not enough to just go to the pool and do the same thing haphazardly.
If you want to progress, you need Well-structured swimming training sessions tailored to your level and goalLearn to swim better, build endurance, go faster, prepare for a crossing, a triathlon, or simply get in shape safely. Throughout this guide, you'll find a comprehensive collection of recommendations, sample sessions, and level-specific plans, rewritten and organized so you can create a solid routine without overcomplicating things.
Benefits and ideal frequency of swimming training
A well-planned swimming routine provides cardiovascular, muscular and mental benefitsWater reduces the impact on the joints, making it a very interesting activity if you have discomfort in your knees, hips, ankles, or shoulders, or if you come from other more strenuous sports like running. Furthermore, many athletes choose it low impact exercises to complement their work out of the water.
With scarcely 30 minutes of continuous swimming at moderate intensity you can burn a significant amount of Calories While working almost all the muscles in your body: back, shoulders, arms, glutes, core, and legs. At the same time, lung capacity and circulatory system efficiency are improved, strengthening the heart without subjecting it to extreme stress as in other high-impact sports.
The mental aspect is also significant: the feeling of weightlessness, the rhythmic repetition of the strokes, and the contact with the water create a very relaxing environment that It helps reduce stress and anxiety. (know the neurobenefits of physical exerciseIt's not uncommon to leave the pool with your head much clearer than when you got in.
Regarding how many days a week it is advisable to swim, most experts agree that a good general guideline is between 2 and 3 weekly sessions to startWith this frequency, clear improvements in technique, endurance, and physical fitness are already observed, provided there is continuity over time.
If you already have a foundation and really want to progress, you can increase the frequency to 3-4 days per week for intermediate swimmers and 4-5 days per week for advanced swimmersAdjusting the workload to avoid overtraining. Rather than obsessing over swimming every day, it's preferable to maintain a consistent, well-planned routine with some variety.
How far to swim according to your level and goals
The “perfect distance” in swimming depends a lot on Your starting point, your technique, your available time, and your main objectiveYou don't need to do 3.000 meters on the first day for the training to be effective; it's better to fall short than to overdo it and end up exhausted.
If you're just starting out and still need to get comfortable in the water, a reasonable range might be between 500 and 800 meters per sessionThis distance can be divided into smaller blocks of 25 or 50 meters with breaks, combining simple strokes (generally freestyle and backstroke) and allowing time for technical drills. The priority at the beginning is to find an efficient stroke and controlled breathing, not the number of meters at all costs.
When technique ceases to be a problem and you no longer get winded at the slightest touch, it's common to move on to sessions of 1.000 to 2.000 meters for intermediate swimmersHere you can introduce variations in rhythm, changes of style (freestyle, backstroke, breaststroke and some butterfly if you master it), work with equipment (paddles, fins, board, pull buoy) and more specific technique blocks.
For advanced swimmers, triathletes, or people preparing for long swims, the distance per session typically increases to 2.000-3.000 meters or even morewith training sessions that last around or over an hour. At this point, the focus is on both endurance and speed, including demanding intervals, changes of pace, advanced technique drills, and high-intensity sessions.
The important is increase the volume graduallyAlways listen to your body. You can play with shorter, more intense sessions some days and longer, gentler ones to accumulate distance, but always with a logical structure that combines warm-up, main part, and cool-down.
Types of swimming training: speed, endurance, and power
To make your swimming workouts complete, it's a good idea to mix different types of sessions throughout the week. This way you work on... top speed, aerobic capacity, anaerobic power, and a combination of bothjust like you would in a race or cycling plan.
A simple scheme that is widely used is to divide the plans into four main blocks: speed training, aerobic endurance training, anaerobic power training, and mixed aerobic/anaerobic sessionsYou can also combine them with training at alternating paces to vary stimuli and improve tolerance to changes in pace.
If you mostly run short distances, you'll want to put more weight on the speed and power sessions...without forgetting some endurance training to maintain your stamina. On the other hand, if your goal is long-distance races or you swim many meters per session, you'll need to prioritize... aerobic endurance training and mixed sessions, occasionally introducing very intense blocks so you don't become a "diesel" without spark.
Whatever your situation, one constant in all types of training is dedicating a portion of your time to technique exercisesDog hands, dead stand, pull, bilateral breathing, kicking drills, etc. Improving your technique saves you energy, prevents discomfort, and makes any speed or endurance work much more effective.
Swimming routines for beginners
If you're a beginner or haven't swum in a while, the wisest thing to do is to organize sessions of 30 to 45 minutes, about 2 or 3 times a weekThe goal is not to get wrecked, but to build a solid foundation of technique and gentle stamina.
Before entering the water, a short swim is highly recommended. dry heating for a few minutes. You can do, for example, a series of basic exercises with your own body weight and resistance bands to activate your body and pay special attention to your shoulders and core.
- 10 squats.
- 10 repetitions of arms forward with elastic band.
- 15 seconds of abdominal plank.
- 10 scapular raises while lying face down.
- 10 strides per leg.
- 10 push-ups (you can do them on your knees if you need to).
- Dynamic stretches for shoulders, hips and ankles.
Once in the water, you can start with a simple aquatic warm-up of about 200 meters Freestyle at a gentle pace, or alternating between freestyle and backstroke if that's more comfortable for you. The important thing at this stage is to find enjoyable sensations, without feeling like you're going crazy.
For the main training for beginners, a technical routine like the one used by some sports schools works very well: 4 sets of 50 meters combining crawl and backstrokeresting for a few seconds between each 50. You can do, for example, 25 meters crawl + 25 meters backstroke and repeat the block, concentrating one day on body alignment, another on breathing, and another on the kick.
After finishing the main part, set aside a few minutes for the coolingSwim 100 meters in your preferred style, relaxing your stroke and lengthening each movement. Get out of the water and spend at least 5 minutes gently stretching the muscle groups you used most, especially your shoulders, chest, back, and hip flexors.
Intermediate training: improving technique and endurance
If you're already comfortable in the pool and can complete several sets without running out of breath, you can take it a step further with training sessions of 45 to 60 minutes, 3 or 4 times a weekAt this level, the key is to combine styles and play with medium distances to gradually accumulate meters without losing technical quality. increase physical endurance.
A typical session for intermediate swimmers might range between 1.000 and 2.000 metersIntegrating freestyle, backstroke, breaststroke, and, if you're proficient, some butterfly. It's also a good idea to start working with equipment like paddles, fins, a kickboard, or a pull buoy to emphasize different parts of the body.
Example of an intermediate session focused on endurance and technique:
- Warm-up – 300 m: mixture of gentle styles (e.g., 100 crawl + 100 backstroke + 100 breaststroke).
- Main series – 800 to 1.200 m:
- 8 x 100 m alternating styles (freestyle, backstroke and breaststroke), resting 15-20 seconds between repetitions.
- 200-300 m of specific technique (recovery exercises, board kick, dead point, bilateral breathing…).
- Cool-down – 200 mSwim very gently in the style that relaxes you the most.
Another way to make the most of 30 minutes in the pool, if you're short on time, is to divide the session into timed blocksFor example, training sessions of 850 to 1.000 meters in half an hour, where you experiment with different strokes and paces, maintaining short rest periods between repetitions. This way, in addition to swimming, you get used to timing yourself, which is very useful for open water swims or triathlons.
At this level you can now enter somewhat longer series (for example, 4 x 200m at a constant pace with 20-30 second breaks) that will help you maintain a good pace over medium and long distances without falling into the classic "I start strong and end up exhausted".
Advanced plans: speed, power, and long sets
Once your technique is established and you can comfortably handle training sessions of an hour or more, you can start playing with demanding sessions of speed, anaerobic power and thresholdHere, high total meters (2.000-3.000 m or more) are combined with intense blocks where you really have to push yourself.
A very widespread scheme for speed work is the series of 50 and 100 meters with moderate rest periods, alternating easy and very fast intervals. For example, you can do 4 sets of 100 meters with a one-minute rest between rounds, where the intensity is progressively increased:
- First set: 75m comfortable pace + 25m hard.
- Second set: 50m easy + 50m hard.
- Third set: 25m easy + 75m hard.
- Fourth set: 100m as fast as possible.
This type of proposal forces us to change rhythm within the same repetitionThis is very useful in real-life situations, such as overtaking a group or navigating a swell in open water. In all cases, it's essential to have a sufficiently refined technique so as not to lose it as soon as the intensity increases.
It is also common to work on the anaerobic power Training sessions consist of distances between 1.250 and 4.000 meters, divided into numerous short, demanding sets, combining periods of intense swimming with relatively generous rest periods. This simulates explosive efforts that may later appear in competition, both in the pool and in open water.
On the other hand, mixed aerobic/anaerobic sessions focus on maintain high pace during medium distances (for example, sets of 200 or 300 meters at high intensity with somewhat longer recoveries), something key to tolerating long periods of fast swimming when the situation requires it, such as in a triathlon with rough seas or in the final stretch of a crossing.
Examples of complete workouts by objective
Beyond the level, it is useful to see concrete examples of swimming training according to the main objective: gain speed, increase aerobic endurance, improve power or mix both capacities in the same session.
A plan of speed training It usually ranges between 1.000 and 3.000 meters in total, always with a clear structure: warm-up, technical block, a section of fast intervals, and cool-down. You can start with 1.000 meters total and, as you progress, increase to 2.000 or 3.000, maintaining the same concept but increasing the volume.
aerobic endurance routines These workouts are designed to prepare you for long distances, typical of open water swimming or triathlons where the swim segment exceeds 10-15 continuous minutes. Here, distances can range from 1.500 to 7.000 meters in a single session, with moderate intensity but maintaining the same pace for as long as possible.
In the block of anaerobic power Relatively short series are combined with very high intensities, something that is reflected in plans of 1.250, 2.500 or even 4.000 meters in which the strong parts are executed almost at the limit, followed by rests that allow the effort to be repeated without the technique collapsing.
Finally, the mixed aerobic/anaerobic sessions They include both intense sections and medium-to-long efforts at a good pace. They usually range between 1.250 and 3.500 total meters, with sets that combine high intensity and relatively generous recovery periods, making them tough but very complete workouts for athletes already accustomed to swimming.
Structured sessions of 30 to 45 minutes
If you don't have much time to train, you can make the most of the pool with very well organized 30-minute sessionsThe key is to think in terms of "series" instead of just jumping into the water and swimming aimlessly.
For example, a 30-minute session to improve endurance and strength could add up to around 850 to 1.000 metersThe workout is divided as follows: a 200-meter warm-up, a main block with repetitions of 50 and 100 meters combining freestyle and breaststroke, and a final 200-meter cool-down. Rest periods and pace are monitored to ensure the total time doesn't exceed a certain limit.
Another interesting option is to focus the session on the leg and core workoutIn this case, after a 200-meter warm-up, you can complete a main set of 500 meters based on kicking (front crawl and backstroke) and finish with a 200-meter cool-down. This is about strengthening propulsion and core stability, something you'll notice a big difference in your stroke.
You can also dedicate a 30-minute session to rhythm controlFor example, do 8 repetitions of 100 meters with very short rests (less than 10 seconds), trying to maintain the same time for each 100. This not only improves endurance, but also teaches you to swim at a steady pace without pushing yourself too hard at the beginning.
To get even more out of short training sessions, it is recommended do a dry warm-up about 10 minutes before entering the water (joint mobility, resistance bands, gentle activation exercises), so that you can dedicate almost all of your pool time to real swimming.
High-performance 45-minute sessions
When the goal is to fine-tune performance in a short time, a good strategy is to use training sessions of about 45 minutes, very focusedas some triathlon programs suggest. The idea is to arrive at the pool having already warmed up on land to make the most of every minute in the water.
An example of a session focused on rhythm control It could add up to 2.000 meters: a first part of 100 meters freestyle swimming, 100 meters kicking, 100 meters with a pull buoy and another 100 meters freestyle swimming, followed by two blocks in which the pace is increased every 50 and every 100 meters, to finish with 100 meters of cool-down.
To work the pure speedAnother 2.000-meter session would include a 200-meter warm-up, followed by 200 meters playing with intense and easy kicks, and another 200-meter block alternating fast and easy sections. This is followed by several short repetitions (for example, 6 blocks with alternating sets of 50 meters of easy and hard sprints) and concludes with a kick and easy swim.
If you are interested in boosting the aerobic performanceA typical session can reach 2.200 meters, including 800 meters at race pace, followed by blocks with pull buoys, paddles, and fins to accumulate distance at a steady pace. The session ends with sections of kicking and an easy swim to cool down.
The sessions are also very useful. threshold workThis involves alternating 100-meter intervals at the best sustainable pace with slightly faster 50-meter blocks. Incorporating pulling and kicking exercises allows for a redistribution of the load between arms and legs, maintaining intensity without overworking any single muscle group.
Warm-up, technique and cool-down
At all levels, it is advisable to respect a minimum structure of heating – main part – coolingMany shoulder and neck injuries and discomforts come from skipping the warm-up or going from zero to one hundred in the first set.
The warm-up can be mixed, combining a few minutes on dry land and a few minutes in the waterOn land, 5-10 minutes of joint mobility exercises for the shoulders, elbows, wrists, hips, and ankles are sufficient, along with some resistance band exercises to activate the muscles involved in the arm stroke. In the water, the usual distance is between 200 and 400 meters at a very easy pace, varying your strokes as long as you feel comfortable.
During the main part, don't forget to dedicate a certain percentage of time to specific technical workExercises to improve hand entry, arm extension, stroke-kick coordination, bilateral breathing, and body position. Incorporating these exercises into well-defined blocks within your training accelerates the improvement of your stroke.
The return to calm, although many are curtailing it, is fundamental for lower heart rate and facilitate recovery100 to 200 meters of very gentle swimming is sufficient, preferably with a style that is comfortable for you (many people choose breaststroke or backstroke to "loosen" the shoulder area), followed by a few minutes of light stretching.
Equipment used: paddles, fins, board and pull buoy
Auxiliary equipment can be a great ally if used wisely. Incorporate fins, paddles, board or pull buoy In certain blocks of your training, it helps you improve technique, gain localized strength, and vary stimuli so that the body doesn't always get used to the same thing.
fins They are very useful for strengthening the kick and focusing the work on legs and core. By offering more surface area for propulsion, they allow you to gain speed with less arm effort, which is ideal for technical blocks or when you want to improve your sense of horizontal position in the water.
swimming shovels They increase the surface area of the hands and, therefore, the resistance in each stroke. They are excellent for developing strength in the shoulders, back, and triceps, but they must be introduced gradually and carefully to avoid overloading the joints, especially if you are still refining your technique.
La table It's primarily used for kicking drills, allowing you to isolate leg work while focusing on propulsion with your feet. It's often combined with fins in specific kick-to-freestyle or backstroke blocks, very common for both beginners and advanced swimmers.
El pullboy It's placed between the legs to keep them afloat and shift the effort more to the upper body. It's especially useful in long sets of freestyle to work on arm pull and body alignment without the legs sinking due to fatigue.
Open water swimming training
The transition from the pool to the sea or lake requires certain adaptations, as in open water There are no lane lines, the water tends to move, and there are no walls every 25 meters.Orientation control and the ability to remain calm in a changing environment become as important as the swimming technique itself.
A good way to start is to plan short training sessions about 10 continuous minutes From there, you can gradually increase the duration until you reach or exceed an hour, depending on your goal. Before you start, it's a good idea to warm up for a few minutes on dry land and then swim gently in the water to acclimatize to the temperature.
To work the orientationThe trick is to choose a fixed reference point (a buoy, a large rock, a building visible from the water) and practice the technique of slightly lifting your head every few strokes to check your trajectory. You can position yourself about 400 or 500 meters from that point and design specific sets.
A practical example would be to perform three sets of about 500 meters each, changing the frequency with which you look at the reference point: in the first set, lift your head every 4 strokes; in the second, every 6; in the third, every 8. Then, complete a single set of 800 meters using the frequency that you found most comfortable and accurate.
During these types of sessions you can also play with different swimming speeds to check if your orientation holds up when you pick up the pace. The final part should include a few minutes of very easy swimming, alternating breaststroke and backstroke if possible, especially if you've been swimming in a wetsuit and want to finish by giving your shoulders a bit of a break.
Swimming and triathlon: specific training
If your goal is triathlon, your swimming sessions should address Typical mistakes of triathletes: poor orientation, too rapid starts, problems swimming in a group, uncontrolled breathing, or difficulties dealing with the waves.
Triathlon-specific swimming plans are usually mixed with the other running and cycling sessions, so they tend to be very efficient in terms of timeThey include blocks of technique applied to open water swimming (side breathing while looking forward, turns around imaginary buoys, swimming "inside" and "outside" other swimmers) and sets at paces similar to those of competition.
In this context, it is essential not to abandon the classic work of aerobic resistance (long sets and continuous swimming) nor the one of speed and power (short, very intense sets with measured rest periods). A solid combination of both will make the triathlon swimming segment less strenuous and more strategic.
To complete the preparation, it is very useful to regularly introduce strength exercises out of the waterThese exercises focus primarily on the upper body, core, and shoulder stability. This helps swimmers better withstand the load of long distances and prevents common swimmer discomforts such as shoulder tendinopathies.
Swimming, when well-structured and combined with strength training and, where applicable, with the other disciplines in triathlon, becomes a very powerful tool for Improve overall fitness, control weight, and take care of joint healthWith consistent planning, 2-3 weekly sessions can already make a big difference, and from there it's just a matter of adjusting distances, intensities and types of sessions depending on how you progress.
