I enjoy swimming, it is a great form of exercise.
I've actually gotten into it myself. It's how I got into decent shape a couple of years ago. I loved how it made me feel
Yeah, one benefit is that it is "low-impact" compared to things like running. Better for your joints.
Yeah, I liked to mix it in with running, to give my body a rest for the pouding on the pavement. What's something more intricate about swimming I may not know?
One thing is that saltier water increases buoyancy, so swimming in the ocean may be easier.
I used to be able to do that when I lived on the coast. I had to move away for school the past couple years, so I don't get to do that anymore. Never realized salt water would make you float more, but I guess that makes sense.
Yup the body has a density of 0.98 compared to water which is why floating is not too hard usually.
