Its been so hot here in Minnesota; everyone has been swimming lots lately, which is a low impact work out
Here in Atlanta is really hot also.That is why it's called Hotlanta.
Do ya'll like swimming? Since the human body is only slightly less dense than water, water supports the weight of the body during swimmin'
In the summer yes.I could spend all day long in a pool.

Science.
Swimming relies on the nearly neutral buoyancy of the human body. On average, the body has a relative density of 0.98 compared to water, which causes the body to float. However, buoyancy varies on the basis of body composition, lung inflation, and the salinity of the water. Higher levels of body fat and saltier water both lower the relative density of the body and increase its buoyancy.
Since the human body is
only slightly less dense than water, water supports the weight of the body during swimming. As a result, swimming is “low-impact” compared to land activities such as running. The density and viscosity of water also create resistance for objects moving through the water. Swimming strokes use this resistance to create propulsion, but this same resistance also generates drag on the body.
Hydrodynamics is important to stroke technique for swimming faster, and swimmers who want to swim faster or exhaust less try to reduce the drag of the
