Why swimming leaves you puffing, even if you’re fit
You can walk five kilometres, thrive in a reformer Pilates class, regularly go to the gym and still find yourself puffed after swimming one lap of a pool.
A lot of women assume this means they are unfit. In most cases, not true.
Swimming challenges the body differently to almost any other form of exercise because it combines breath control, resistance, coordination and cardiovascular fitness all at once.
On land, breathing is automatic. In water, breathing suddenly becomes something you have to think about. Even relaxed swimming requires controlled breathing patterns, timing and rhythm. If breathing becomes rushed or shallow, the body starts working harder very quickly.
Water itself also creates constant resistance. Every movement through water requires more effort than moving through air, even if it feels gentle. That is why swimming can feel surprisingly tiring despite being low impact.
Then there is the psychological side.
Many people unconsciously hold tension in water, especially in the ocean. Tight shoulders, clenched hands and shallow breathing all increase fatigue. Ironically, the harder people try to “push through”, the harder swimming often feels.
Different types of fitness also do not always transfer across neatly.
Walking and running primarily build cardiovascular endurance on land. Pilates and yoga improve strength, mobility and body awareness. Gym training builds muscular strength and stability.
Swimming uses elements of all of those things simultaneously while also requiring the body to regulate breathing under physical effort.
Ocean swimming adds another layer again. Waves, currents, salt water and changing conditions mean the body and brain are constantly adapting. That is why even strong pool swimmers can initially feel challenged in the ocean.
The good news is swimming fitness improves surprisingly quickly.
The key is to stop treating swimming like punishment or performance.
Float between laps. Slow your breathing. Mix swimming with floating, gentle kicking or simply standing waist deep in the ocean. Build confidence before intensity.
