Why open water swimming is especially good

Open water swimming can help ease joint and muscle pain, especially for people with conditions like osteoarthritis. It also strengthens muscles, keeps your joints flexible, and supports a healthy heart.
What makes it extra special is being out in nature. Fresh air, peaceful surroundings, and moving water can help reduce stress, lift your spirits, and even ease feelings of loneliness. Many venues offer support and safety measures to help you build confidence.

type of movement

Cardio
★★★★☆

Cardio

Open water swimming is great for cardio because moving through the water makes your heart work harder.

  • Always get into the water slowly to allow your body to adjust
  • Get out when you start feeling cold, there’s no shame in a wetsuit…
  • Breathe calmly focussing on the out breath
Strength
★★★☆☆

Strength

Open water swimming builds strength because the water pushes against you as you move.

  • This makes your muscles work harder without hurting your joints
  • You could try some squats, lunges and upper body exercises in shallow water.
Balance
★★☆☆☆

Balance

Open water swimming helps balance because the water moves gently around you, making your body work to stay steady.

  • This helps strengthen your core and improve control
  • Try closing your eyes and counting to 10 and allow your body to adjust with the water
  • If you struggle with balance, you might want to wear a life vest to start with.
