GET A PAIR OF Moving Free® Water-Fill Plastic WEIGHTS with Mirabai Holland's  Moving Free Mind-Body Workout DVD. The water-fill plastic dumbbells fill up to 3 lbs. each for workouts on land and are used empty, filled with air, for resistance for working out in the water.  Mirabai uses the weights partially filled on land for a unique Cardio interval that features the rhythmic movement, feel and sound of flowing water in the weights. 

Then she fills up the weights for a light strength workout. She follows up with some Abdominal Toning exercises and stretching for the muscles you just worked and ends with a stress reduction meditation. Next, Mirabai demonstrates how to use the water-filled weights in the water for a full body Aqua Exercise Routine.
