I am looking for alternatives to doing effective cardio running in the water. Big plus if there are ways to get all of the same muscles to fire, to scale workouts easily, to be able to have an ultra intense workout, for options that someone with foot or knee issues could do, and a plus if it can be done in most "larger" pools.
I would like an answer that does not rely on the runners feet ever touching something. I would like some workout plan examples, equipment needed, progressions, and good insight in the answer!
