When using buoys or noodles in an aqua class, are the standards the same for training as on land? For example, 3 sets of 10-12 reps, to fatigue. Is it “normal” to do 40+ “abdominal shoot throughs or crunches” with a noodle? My concern is lack of good form and/or injury. Also are any good articles or information regarding this that I can read and share?
