Swimming and Water Exercise: Gentle, Joint-Friendly Fitness at Any Age

There is something uniquely restorative about water. The moment you slip into a pool or the sea, your body feels lighter, joints feel freer, and movement becomes easier. For many women over fifty, swimming and water-based exercise become a favourite way to stay active: kind to joints, refreshing, sociable and adaptable to every fitness level.

Whether you are a confident swimmer, a nervous beginner or someone who has not been in a pool for decades, this guide explains the benefits of water exercise, how to get started, simple exercises to try, and practical tips on kit, safety and aftercare.

This is general information, not medical advice. If you have a heart or lung condition, high blood pressure, epilepsy, skin conditions, open wounds, recent surgery, or are unsure whether water exercise suits you, ask your doctor or physiotherapist first.

Why water exercise is so beneficial

Kind to joints

Water supports much of your body weight, reducing the load on hips, knees and the spine. This makes it a popular choice for people with joint pain, arthritis or extra weight, and for those returning to activity after a break. Many physiotherapists use water-based exercise (hydrotherapy) in rehabilitation.

Resistance in every direction

Water provides gentle resistance to movement in every direction, so even simple movements work muscles. The faster you move, the greater the resistance.

Heart and lung fitness

Swimming and brisk water exercise can count towards the moderate aerobic activity that health guidelines recommend — around 150 minutes a week for adults.

Flexibility and balance

The support of the water allows a greater range of movement for many people, and moving in water challenges balance in a safe environment where a stumble is cushioned.

Wellbeing

Many people find water exercise relaxing and mood-lifting, and pool sessions and classes offer a sociable atmosphere. Open-water swimming has also become popular for the sense of wellbeing many people describe, although it comes with additional safety considerations (see below).

A note on bones

Because water supports body weight, swimming is less "weight-bearing" than walking or strength training. If bone health is a priority, combine water exercise with weight-bearing activities and strength training (see our guides to walking and strength training).

Types of water exercise

Swimming

Different strokes work the body in different ways:

• Breaststroke: popular and sociable. Some people find the head-up style strains the neck and lower back; putting your face in the water and breathing rhythmically can help. Swimmers with knee problems may find the kick uncomfortable.
• Front crawl (freestyle): efficient and good for fitness; learning to breathe to the side takes practice.
• Backstroke: good for posture and the upper back, and the face stays out of the water.
• Gentle sidestroke or elementary backstroke: relaxed options for less confident swimmers.

Water walking and jogging

Walking or jogging in chest- or waist-deep water is a simple, effective workout, suitable for non-swimmers and those who prefer to keep their feet on the floor.

Aqua aerobics (aquafit)

Group classes set to music, combining aerobic movements, strength exercises and stretches in shallow water. They are sociable and suitable for many fitness levels, as you can adjust the intensity.

Aqua jogging

Running movements in deep water, using a flotation belt. Intense but joint-friendly.

Hydrotherapy

Warm-water exercise, often supervised by a physiotherapist, for rehabilitation and conditions such as arthritis.

Getting started

Find the right pool and session

• Check local pools for adult-only, quiet or women-only sessions, lane swimming by speed, and aqua aerobics classes.
• Ask about water temperature. Warmer pools are more comfortable for gentle exercise and for people with joint pain; cooler pools suit vigorous swimming.
• Look for accessibility features such as steps, handrails, hoists and accessible changing rooms, if needed.

Build up gradually

• Start with short sessions — perhaps fifteen to twenty minutes — and build up.
• Mix swimming and water walking, or alternate lengths of different strokes.
• Rest at the wall whenever you need to.
• Aim for regular sessions, perhaps two or three times a week.

Swimming lessons for adults

It is never too late to learn to swim or improve your technique. Many pools offer adult lessons, from complete beginners to improvers. Lessons can help with breathing, confidence and efficient technique, making swimming more enjoyable and less tiring.

A simple water workout

This routine is designed for chest- or waist-deep water, holding the side for support if needed.

Warm-up (five minutes)

• Water walking forwards, backwards and sideways.
• Shoulder rolls under the water.
• Gentle arm sweeps, moving arms forwards and backwards through the water.

Main set (fifteen to twenty minutes)

1. Brisk water walking: walk briskly across the pool, swinging your arms.
2. Knee lifts: march on the spot, lifting knees high.
3. Leg swings: holding the side, swing one leg forwards and backwards, then out to the side. Switch legs.
4. Calf raises: holding the side, rise onto your toes and lower.
5. Wall push-ups: facing the side, place hands on the edge, lean in and push back.
6. Arm curls: with elbows at your sides, bend and straighten your arms against the water's resistance, palms facing up then down.
7. Jumping jacks: jump, moving legs apart and together, with arms sweeping under the water. Reduce impact by stepping instead of jumping.
8. Cross-country ski: alternate stepping one leg forward and one back, swinging opposite arms.
9. Swimming lengths at a comfortable pace, if you swim.

Cool-down (five minutes)

• Slow water walking.
• Gentle stretches holding the side: calf stretch, hamstring stretch, chest stretch.

Kit

• A comfortable swimsuit with good support. Many brands offer swimsuits designed for mature figures, with built-in support, tummy control panels, adjustable straps or chlorine-resistant fabrics that last longer.
• Swim shorts or leggings if you prefer more coverage.
• Goggles that fit well and do not leak; prescription goggles are available.
• A swimming cap to protect hair and keep it out of your face.
• Pool shoes or flip-flops for poolside and changing rooms, to reduce the risk of slipping and verrucas.
• Optional equipment: woggles (foam noodles), kickboards, pull buoys, aqua dumbbells, gloves and flotation belts. Many pools provide some of these.
• A towel, warm layers and a snack for after your swim.

Staying safe

• Know your limits, and swim in areas appropriate to your ability.
• Swim where there is a lifeguard if you are a less confident swimmer.
• Enter the water slowly, particularly in cold water, to let your body adjust.
• Take care on wet surfaces around the pool and in changing rooms.
• Stay hydrated; you can become dehydrated while swimming even though you are in water.
• Avoid swimming after a large meal or alcohol.
• Stop if you feel unwell, dizzy, short of breath or have chest pain, and seek help.

Open-water swimming

Swimming in lakes, rivers and the sea can be invigorating, but it carries extra risks: cold water shock, currents, tides, changing weather and water quality. If you are interested:

• Join an organised group or club with safety cover.
• Never swim alone.
• Wear a brightly coloured cap and use a tow float to be visible.
• Acclimatise gradually to cold water, and get out before you become too cold.
• Check local conditions and water quality reports.
• Speak to your doctor first if you have heart or circulation problems, as cold water places stress on the heart.

Caring for skin and hair afterwards

Chlorinated pool water can dry the skin and hair.

• Shower before and after swimming.
• Wet your hair with clean water before putting on a cap; hair absorbs less pool water when it is already wet.
• Use a gentle shampoo and conditioner after swimming. Clarifying shampoos designed for swimmers can remove chlorine build-up; grey and blonde hair can sometimes take on a greenish tinge from pool chemicals, which these shampoos help prevent (see our guide to going grey with style).
• Moisturise your skin after drying.
• Rinse swimsuits in cool water after each use to extend their life.

Overcoming nerves and self-consciousness

Many women avoid the pool because they feel self-conscious about their bodies, worry about being slow, or have had a frightening experience in water. These feelings are very common, and there are gentle ways to ease them:

• Choose quieter times or adult-only sessions, often early morning or mid-afternoon.
• Wear what makes you comfortable: a supportive swimsuit with a matching wrap or swim dress, swim leggings or a rash vest.
• Start in the shallow end with water walking, and stay close to the side until your confidence grows.
• Remember that everyone is focused on their own swim. Lane swimmers are usually counting lengths, not looking at others.
• Book lessons if fear of water is holding you back; adult lessons are patient and private or in small groups.
• Go with a friend for moral support and company.

Water exercise on holiday

Hotel pools, lakes and the sea are lovely places to keep active while travelling. Check depth and conditions before entering unfamiliar water, swim where lifeguards are present, use sunscreen and a hat between swims, and take extra care with currents and waves at the beach. A morning swim before breakfast can be one of the most peaceful moments of a holiday.

Making it a habit

• Schedule your sessions at regular times.
• Go with a friend or join a class.
• Track your progress: lengths swum, time spent, or how you feel.
• Set goals: learning a new stroke, swimming a mile over a session, or taking part in a charity swim.
• Reward yourself: a post-swim coffee or a warm sauna, where available and suitable for you.

The bottom line

Swimming and water exercise offer gentle, joint-friendly fitness that suits almost everyone, whatever their age or ability. Start gradually, choose sessions and classes that suit you, invest in comfortable kit, stay safe, and care for your skin and hair afterwards. Combined with walking, strength and balance work, regular time in the water can help you feel stronger, more flexible and wonderfully refreshed.
