I used to conduct an aquatic cardio kickboxing class when I had better access to a pool. It ran for a while but I no longer work at that facility since starting my own business. It was real popular though, and to a wide variety of people. Seeing as how I can no longer offer it, I would love to see someone passionately reignite this one.
I have taught at CC’s for 13 years. Deep in larger out-door pools always goes over well~ provided equipment is available and the class participants are able. I also enjoy teaching aqua KB: multi direction kick, step, lunge w/jack choreography and punching w/aquabells. Besides what is listed, check out Karen Westfall (water works) and Craig Stuart. ESP noodle video is intervals of strength, cardio, and suspension w/some aqua plyos mixed in. Simple choreography w/speed changing and interval work always seems to fly well since this challenges fit pp and seniors. If hot pool ie: MS or Arthritis: check out Ai Chi (AEA) or Aqua Tai chi. Pilates can also be done deep or shallow. Dance in the water is also popular some places for seniors. Hope that helps.
