Fancy getting active gently this summer? Good news: no need to sweat it out at the gym. Aqua aerobics is the perfect ally for anyone who wants to work their muscles, engage their core and stay active on a regular basis, all while enjoying the pool or the sea.
Thanks to the natural resistance of water, every movement makes your muscles work that bit harder, without putting stress on your joints. And it’s fun, accessible to everyone and easy to fit into an ordinary swim!
Here are 10 simple aqua aerobics exercises with no equipment to try at your next swim. Ready to turn your time in the water into a real fitness session?
1. High knees
Standing in the water, lift your knees alternately towards your chest as high as possible, keeping your back straight and your core engaged. This aqua aerobics exercise is perfect for targeting the core while boosting cardio. It also gets your thighs working. Ideal for starting your session with energy!
Duration: 3 sets of 30 seconds.
2. Jumping jacks in the water
Aquatic jumping jacks are a gentle yet energising take on the classic floor exercise. By jumping to spread your arms and legs in the water, you engage the whole body: legs, glutes, arms, abs… The water provides natural resistance that intensifies muscle work while staying gentle on your joints. This dynamic movement works the whole body and gets your heart rate up, with zero impact.
Duration: 3 x 1 minute
3. Flutter kicks

Floating or holding the pool edge, perform rapid kicks with straight legs, moving up and down. This aqua aerobics exercise works the thighs while engaging the glutes and deep abdominals. Perfect at the end of a session or as a complement to a more cardio-focused exercise.
Duration: 3 sets of 20
4. Vertical scissors
Perform scissor movements with your legs, alternating up and down while keeping your torso stable. The core work is intense, the leg muscles are engaged with every movement, and the deep abdominals naturally contract to maintain balance. This exercise is perfect for working your muscles without straining your back or knees.
Reps: 3 sets of 20
5. Running on the spot
Run on the spot in the water, lifting your knees dynamically and swinging your arms in sync. This simple movement turns your session into a mini cardio workout, ideal for working your tummy and the whole body. Thanks to the water, you get moving while engaging your deep muscles without even realising it. A true aqua aerobics classic, not to be overlooked.

Duration: 3 x 30 seconds in each direction
9. Rear leg kick

Reps: 3 x 15 per leg
10. Floating leg hold
Floating gently or holding onto the pool wall, extend both legs in front of you horizontally and hold the position.

Duration: 3 x 30 seconds
