Soo-prise, suprise, suprise! So you study up, practice, and improve. Swimming is where it's at.
Just don't think about the urine.
In the true spirit and intent of this thread, I'll poo poo on your swimming suggestion.
I've tried swimming for cardio fitness in the pool at various times over the years.
On a serious note, it makes sense and seems like the perfect fitness activity.
BUT, for me, I loathe doing it ...go figure.
Treadmill incline walking, stair climber, elliptical and hiking are all enjoyable and "fun" for me.
Cycling should work but it ends up giving me hemorhoids
