United States: A research paper in BMJ Open documents that water aerobics delivers valuable weight reduction advantages and waist-size decreases to overweight and obese populations.
Water-Based Workouts Aid Weight Loss
The study team at Pukyong National University in South Korea under the leadership of senior investigator Jong-Chul Park investigated 10 clinical trials that included 286 participants. Individuals who practiced water aerobics for longer than 10 weeks achieved an average weight loss of 6 pounds together with more than one inch reduction to their waist, as reported by HealthDay.
Why Water Aerobics Works

The supportive features of water buoyancy make it a suitable exercise for overweight individuals because it protects their joints. Participants achieved noteworthy weight reductions and waistline decreases yet the studies failed to establish changes in BMI together with body fat percentages.
A Variety of Water Exercises
The reviewed studies tested different water-based workouts, including:
✅ Water aerobics
✅ Zumba dance
✅ Yoga
✅ Jogging in water
Participants exercised for one hour per session, two to three times per week, over six to 12 weeks (a total of 36 to 84 sessions).
Stronger Effects in Women, Limited Data on Men
The study found greater weight loss effects in women, though limited male participation restricted the ability to assess benefits specifically for men.
A Promising Tool for Weight Management
The study showed that water aerobics provides effective workout benefits for overweight and obese people regarding both their physical composition and their health status.
While acknowledging the benefits they proposed extended research on extensive participant samples and a direct comparison between water aerobics and alternative workout options.
