All those people around and you have that whole section to yourself?????????

Keep the arm movements slow and smooth rather than jerky as you are training for water so try flow like water.

Next is your knees need to compress and extend to move you rather than thinking that your arms do this.

Looking good 👍

I'd suggest trying to keep your elbows up through the turns to keep your back straight and use your arms to bank like an aeroplane so you can get your head lower.

All I can say is you’re very good Well done
