How Long Does It Take to Lose Weight Doing Water Aerobics?

Water aerobics, also known as water exercise, is a type of exercise performed in shallow water such as a swimming pool. It involves doing various aerobic movements and exercises in water, using the resistance of water to provide an intense workout to increase fitness and health. 

Water aerobics can be an effective method for weight loss in seniors, typically burning as much as 423 calories per hour with vigorous exercises and incorporating continuous movement. With sessions of 30-45 minutes held 4-5 days per week, most seniors can expect to lose around 0.5 to 1 pound per week, however this can vary based on factors such as individual metabolism and diet. For maximum results, water aerobics should be combined with a healthy, low-calorie diet and regular participation is key to experience long-term benefits and sustained weight loss.

Some key benefits of water aerobics for seniors include:

  • Low Impact: The buoyancy of water reduces stress and impact on the joints, making water aerobics an ideal form of exercise for seniors. Water provides natural resistance on the body, working the muscles without putting pressure on joints.
  • Increased Mobility: Water aerobics improves flexibility and range of motion in seniors. Doing exercises in water makes the movements easier and reduces risk of strains and sprains.
  • Fall Prevention: Water provides a stable environment for performing exercises, reducing risk of falls or injuries. The water provides support and balance for seniors as they move.
  • Strength Training: Water resistance helps strengthen muscles and bones without putting strain on the joints. Water aerobics can slow down bone density loss in seniors.
  • Cardiovascular Exercise: Water aerobics elevates the heart rate, improving cardiovascular health. The resistance helps seniors get an efficient cardiovascular workout.
  • Weight Loss: Water aerobics burns substantial calories, helping seniors manage weight as they get older. The resistance helps tone muscles while burning fat.

Is Water Aerobics Good for Weight Loss?

Water aerobics can be highly effective for weight loss, especially among seniors and those needing low-impact exercise. The workouts burn significant calories — up to 423 per hour in vigorous sessions — and help build lean muscle mass, which boosts the basal metabolic rate, leading to more calories burned throughout the day. When combined with a healthy diet, frequent water aerobic sessions of 30-60 minutes can typically result in a weight loss of 0.5 to 1 pound per week.

How Much Weight Can You Lose With Water Aerobics?

Below is a table summarizing the information on how much weight you can lose with water aerobics based on the calorie burn and hours worked.

Frequency (Days/Week)Duration per Session (Minutes)Estimated Calorie Burn per SessionEstimated Weight Loss per Week (lbs)
330-45300-4230.25 – 0.5
4-530-60400-7050.5 – 1
630-45300-4231 – 1.5

Note: The estimated calorie burn per session may vary based on individual factors such as weight, intensity of exercises, and metabolism. The weight loss values are approximate and can be influenced by other factors like diet and overall physical activity.

What is the Role of Water Aerobics in Weight Loss?

Water aerobics can be an excellent and realistic option for senior citizens looking to lose weight. Here’s how it contributes to weight loss:

  • Calorie Burn: Water aerobics burns significant calories – as much as 423 calories per hour with vigorous exercises. The water resistance requires muscles to work harder.
  • Continuous Movement: There are no breaks in water aerobics. Seniors keep moving throughout the session for maximum calorie burn.
  • Muscle Building: Building lean muscle mass results in higher basal metabolic rate so more calories are burned daily.
  • Fun Workouts: Water aerobics is enjoyable and seniors are likely to sustain an exercise program they like for a long time.
  • Appetite Control: Regular exercise suppresses appetite hormones resulting in lower calorie intake.

For effective weight loss, water aerobics should be combined with healthy low-calorie diet. Most seniors can lose 0.5 to 1 pound per week if exercising for 30-45 minutes, 4-5 days per week. Greater frequency and longer sessions lead to faster weight loss.

How Does Water Aerobics Benefit Joint and Bone Health in Seniors?

The low-impact quality of water aerobics makes it ideal for seniors to improve joint and bone health. Here are some key benefits:

The water’s buoyancy means that the body weighs only about 10% of its actual weight during the workout. This reduces stress on the joints significantly.

The water resistance provides an excellent muscle workout without jarring movements, high impact, or heavy loads on the joints, bones, and ligaments. 

Water aerobics improves strength and endurance which supports the joints and bones. The muscles around the joints get a workout which provides more stability.

The range of motion improves as seniors stretch and reach in the water, increasing mobility and flexibility of the joints.

It helps increase bone density and prevent bone loss especially in elderly women after menopause. The resistance applied by water strengthens bones.

Water reduces inflammation in joints and muscles allowing greater mobility. It eases the symptoms of arthritis or back pain.

It does not damage joints or bones like conventional impact exercises. Water cushions the body and provides cushioning during the workout.

How Can Water Aerobics Improve Cardio, Strength, and Endurance in Seniors?

Water aerobics provides an all-round workout to improve cardiovascular health, strength, and endurance in seniors:

Cardio Workout

  • Gets heart rate into target zone for sustained periods to improve heart health.
  • Water resistance makes heart and lungs work harder improving cardio endurance. 
  • Different moves like jogging, kicks, jumps, etc. keep heart rate elevated throughout workout.
  • Better circulation and blood flow occurs from continuous body movements.

Strength Training

  • Water resistance and buoyancy provides full body strength training.
  • Various exercises like leg lifts, arm curls, presses, etc. target all major muscle groups.
  • Muscles work harder due to continuous resistance applied by water.
  • Improved strength makes daily activities like climbing stairs, carrying groceries easier.


  • Keeping body moving throughout the session improves aerobic endurance.
  • Constant motion with no breaks boosts stamina, energy and lung capacity.
  • Water aerobics classes are usually 30-45 minutes long to build endurance.
  • Coordination and range of motion improves allowing longer training periods.

How Frequently Should Seniors Engage in Water Aerobics?

The American Heart Association recommends seniors and older adults engage in water aerobics at least 2 and a half hours per week.

For general fitness, seniors can do water aerobics 30-45 minutes a day, 3 days a week. For weight loss, aim for water aerobics 4-5 days a week for 30-60 minutes per session.

For maximum benefits, some seniors do water aerobics daily or 6 days a week. Avoid doing strenuous water aerobics 2 days in a row. Have a rest day in between for recovery.

Have proper warm up, cool down stretches before and after each session. Stay well hydrated before, during and after water aerobics. Listen to your body. Take breaks or reduce frequency if feeling fatigued or joint pain.

Maintaining a regular water aerobic exercise regimen is key for seniors seeing sustained benefits on bone and joint health, weight loss, cardiovascular endurance.
